Atomic Coffee Maker Adventures Part 2

I mentioned that I considered Andrew and I were lucky to acquire our Atomic coffee makers for $250 plus postage and $178 plus post.  In both cases the postage from Interstate came to $30.  Here is what they are selling for on ebay.



By the time the postage is added even the cheap one is over $400 and the others are just under and just over $600.




Following my initial cleaning of the old Atomic coffee maker, I managed to get some pretty nice looking coffee out of it.  But even after a number of shots it still tasted a bit off.

As a matter of interest, when my son Andrew got his at Christmas, I designed a water level gauge that allows us to consistently fill the Atomic with the right amount of water, so that the stream stops and sputters just as the level reaches an ounce.

We also solved the problem of Atomic coffee tasting burnt by simply placing a glass in the aluminium bowl.  The glass is marked so we can always be sure if we get one or two actual shots.  We can of course vary the amount to taste.

In the last post I wrote about freeing up the filler knob without damaging it, but I still could not get the 'shower screen' loose to clean behind it, so I back flushed.  I was pretty sure there would be a little residual gunk up behind it, because there had been in Andrew's Atomic.  Today I finally managed to get the aluminium screen free, although one of the screws broke in the process.  It isn't a big problem, as the screen is held in place in the head by a silicone gasket.


Above is what it looked like up in the head, behind the screen.  You can just see the broken screw at the top, and the hole at the bottom where one came out ok.  You can also see where I scraped some of the scale and dead coffee grounds off the water pipe.
I spent ages scraping with a screwdriver and then using various Dremel tools in there cleaning it up, but it ended up pretty clean.


And this is what was behind the screen.  No wonder the coffee had a hard time getting through and only came out in drips.  And also probably the reason it tasted really bad.

The filler knob is also the safety pressure valve.  It had been venting too easily, so while I was messing with things I took that apart and cleaned the seat where it seals, cleaned the rust off the shaft of the screw with a Dremel wire wheel, and cleaned the actual hard rubber seal material.  I also gave the spring a clean and cleaned the threads, then put the whole thing back together.  I'm almost sorry I ordered a new one, because it now works perfectly despite the main filler neck seal being hard as a rock.

So where are we now?
For a start, I have it on good authority that the Atomic coffee maker does not produce proper espresso because it operates at too low a pressure.  That's ok.  It makes a delicious short black that tastes very, very close to the real espresso I get if I order one from The Coffee Club or Gloria Jeans.  So I am happy enough with that.  
And that makes a rather nice Atomic Cappuccino!

I also have it on good authority that the Atomic coffee maker cannot make a shot of whatever we call it (if we are not going to call it 'Espresso') with crema.  Now, it is true, you don't get the foamy crema mixed through the shot and settling to the top after the shot is put aside.  But you do get a layer of fine gold a few millimetres thick across the top. 

As for foaming milk.  I like fine microfoam and the Atomic has two holes in the nozzle that point downwards and outwards at an angle.  That makes it almost impossible to get a swirl going in the jug.  It is designed to make froth rather than fine foam and it is excellent at that - if you like a 'meringue peak' on your coffee.
But it isn't all bad and I'm slowly discovering some tricks that make a fairly fine foam.

It will take a while to get a brew that is close to the Krups 871 sweet syrupy and really strong coffee from the same amount of ground beans, and I'll be working on adapting to the milk technique for a while.  But for now, it is working nicely and the coffee is pretty close to what I get in a cafe.  Except I do NOT do Latte Art.

As a matter of interest, here's the bowl with one of the water gauges in place.  We fill the bowl until the water just reaches the flat turned in piece on the aluminium strip  That way we get the same amount of water every time.  
As mentioned earlier, by using a glass in the bowl, the coffee doesn't get burnt.  If I am making a 'long black' style using more water, so I can just have an ordinary black coffee or a coffee with milk, I can skip using the gauge and just have the coffee flow into the bowl. To do that, I just pour a full bowl of water into the Atomic.

Above is the cappuccino from the coffee in the previous photo.  The foam is not perfect, but it is about as fine as I can get out of the Atomic so far, and getting close to the texture I get from the Krups 871, finer than I get out of the Breville pump machines.

The coffee tastes better than either of the Brevilles, but still not as perfect as the Krups, either as an espresso style or as a cappuccino, but that's probably because I mastered the Krups over many years.  

Something else that is handy to know.  Because of the bulk of the Atomic's aluminium body it takes forever to heat that, then heat the water in it.  
Water will boil much more quickly in an ordinary kettle or pot, so to save gas, we usually boil a small amount of water and pour that into the Atomic.  That pre-heats the Atomic and once it is on the stove it takes a fraction of the time it normally would to make a coffee.

Conversely, once the Atomic is hot, pouring in sufficient water for a second coffee takes little time because the Atomic is already hot.

There's a trick to this too.  If you empty residual water in the Atomic into the bowl, you only need to top it up to the level you want in the bowl and pour it back in.  That way you get the exact amount you are after.

BUT !!!!!   

NEVER touch the Atomic body, steam wand or any other parts with your bare hands until it is cold or cool.

If you need to empty it to refill it, use a wet towel to hold it.

You will probably only grab a hot part of an Atomic once.  The lesson is very sudden and very painful...

Coffee O'clock? Atomic Coffee Maker Adventures

I've been posting about Linux stuff for so long that I sometimes forget this blog is also about The Whitsundays and Me!

So here's my first coffee post in probably 2 or 3 years.  :-)

A friend introduced me to the Atomic coffee maker many years ago, and before that I rarely drank coffee because I hate instant coffee.  He and his wife gave me the first coffee maker I ever owned, an electric model that works on the same principle as the Atomic.


You put water in the coffee maker, put ground coffee in a filter basket, put the basket in the holder and put the holder in the top part of the coffee maker.

The water boils, the steam pressure forces some of the water up to the top of the machine where it is forced through the ground coffee under pressure.  Then the residual steam is used to foam milk if you want a cappuccino or latte.

I have had several of these electric boiler/steam machines since then, but never had the urge to spend an exorbitant amount of money for an Atomic.  Second hand 40 to 50 year old ones are going for over $500 and even crappy looking ones with some broken bits are going for $300 plus.

But when my son wanted one to use in Japan, because the electric appliances there are a pain in the neck, we began looking around.  We got what we thought was the buy of the year.  An Atomic in pretty good condition and nice looking for $250.  With delivery it was $280.  A nice deal.  And he has been learning how to drive it since.

But I was interested in a cheap one if it ever came up to take to Isla Verde, where we don't have a reliable source of power for electric appliances.  the resort runs on a couple of small solar panels, some batteries runing a small inverter, and a generator for more or less emergency use.  So when one of us saw one that had been advertised on ebay for some time and had only a few bids, we got interested.  It looked horrible.  There were a few made with an enamel paint over them.  Orange, red and brown seem to be the colours and not all that many were made.

This one had obviously been used in camp fires and was horribly burnt.  Also, the steam wand looked all corroded and so did the screen and screws up inside the top.  The advert said the filler knob was seized too.  So I placed a low bid, knowing they always go crazy in the last half hour.

This one did, and I won it by about a dollar!  And when it arrived it looked just as bad as it had in the description.  But it was ridiculously cheap even if I had to spend the planned $100 or so for a new knob and some seals.  When the filler knob becomes seized in the neck, it is almost always broken by the person trying to free it.  All the advice I found on Google and videos on Youtube had people using various kinds of multi grip pliers on their knob or putting their knob in a vise.

I thought abo tit for a while.  The knob gets seized in the hole because people leave it in the hole after they finish.  The aluminium body of the Atomic gets really, really hot, but the bakelite knob stays cool.  So when the aluminium cools down, the hole is dry and your knob can get stuck in the hole.

I wondered whether anybody had ever tried reversing the process.  So I heated the Atomic in boiling water.  Then I was about to look for some decent multi-grips when I had one of those sideways thoughts I am infamous for.  I wanted to put steady, gentle pressure and grip on a round fragile surface.

So instead fo pliers I grabbed a webbing oil filter wrench and a socket ratchet handle.  And nothing happened.  So I got a half inch breaker bar instead.  And my knob moved.  A little bit more pressure and my knob was free of the evil hole.


The threads were in good condition and the knob was undamaged.  But when I turned the Atomic over some grains of sand textured whitish powder fell out.  I hit it with the palm of my hand and got more, so I went around it with a hammer.  This is part of the result!

There was more, but I had washed it away before I realised I should be documenting the experience.  Once I had loosened and emptied as much as I could I washed the inside out with vinegar over and over, then with soap and boiling water to try to wash out any residual acid (vinegar) because I have no idea what leaving that stuff in there would do to the aluminium.

The screws in the top still can;t be removed, so I reverse flushed that part and got lots more horrible gunk out.


 Then I stuck it on the gas stove with enough water to make a single shot of coffee.


It tasted horrible with the residual taste of WD40 (I forgot to mention trying to loosed those screws) and vinegar and soap, but it was definitely coffee and about the right strength.

So on my $178 Atomic, everything works like new.  Next post I will have put a few lots of coffee and water through the thing so after I get one really good tasting coffee, I'll post the steps for my next brew.

Gigabyte BRiX BACE-3150 OS Choice PLUS Micro SD is working in Mint 17.3 and 18.1

Wow!  it has been an interesting week with the BRiX BACE-3150.

I changed operating systems several times and came to the conclusion that in Mint 18.1,  Plasma 5.x is useless on the BRiX, XFCE is not much better and Cinnamon works well, but without my 'different wallpapers on each workspace'.



The best performer in Mint 18.1 was defintely Cinnamon although once I found and enabled an extension to allow me to change workspaces by scrolling the mousewheel on the desktop, I started to get the off mouse cursor artefact left on the screen for a few bried moments.

Because I always have two root partitions on my drive, I am able to install a new Linux distribution without using VirtualBox and without messing up my original distro.

(Mint 17.3 KDE with kernel 4.8)

That meant it was easy to drop back into Mint 17.3 and look seriously at any advantages I saw in Mint 18.1, and honestly, there was only one.

The BRiX has a built in Micro SD card reader that didn;t work in Mint 17.1 or 17.3, but it was working in Mint 18.1.  So I checked the Kernel.


So just out of curiosity I installed a later kernel in Mint 17.3 using the following commands in Terminal.


cd /tmp; wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-headers-4.8.0-040800_4.8.0-040800.201610022031_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-headers-4.8.0-040800-generic_4.8.0-040800.201610022031_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-image-4.8.0-040800-generic_4.8.0-040800.201610022031_amd64.deb; sudo dpkg -i *.deb
sudo update-grub
After a reboot, this is the kernel I now have in Mint 17.3 KDE.
And a quick check of Dolphin shows the Micro SD card mounting, opening and unmounting perfectly
The next task, once it was tested was to use Grub Customizer to rearrange the menu entries.
The last to steps are to Save, and then Write the image to
the Master Boot Record, in my case on /dev/sda
So these few days have achieved something. I know not to waste my time
on Mint 18.1 KDE or indeed any KDE with the New Plasma 5.x.
I found that XFCE has serious screen tearing issues, but only with text.
I found a workable alternative in Mint 18.1 Cinnamon although it still leaves
a lot to be desired.
My overall decision is that the best Linux to run on a Gigabyte BRiX BACE-3150
is Mint 17.3 KDE with the 4.8 kernel, which works great (so far) with the BRiX built in hardware.

BRiX BACE-3150, Mint 18.1 XFCE and Screen Tearing




I have written about this problem of horizontal tearing in text in several of the last few posts and it deserves a section on its own where I can mess with ideas.  This is the problem I am talking about.


At Feb 28 2017 this is where I am,

While trying various settings I found 'Synchronise drawing to the vertical blank'.  Now I'm not sure what this means and I will need to do some searching, but there seems to be some improvement.  Below is a screen shot.  It is in Settings, Window Manager Tweaks, and is the third item in the dialog below.


There is still some tearing in text initially, but seems to be disappearing on its own after half a second without my having to move the mouse.

One more setting to play with is under System Settings > Appearance.

There are a few things here like Subpixel Rendering that can improve the display of fonts on LCD displays.



UDDATE a couple of days later.  My Mint 18.1 XFCE is now Mint 18.1 Cinnamon for the moment.

Installing Cinnamon into XFCE and logging into Cinnamon, there is so far none of the text tearing that was plaguing XFCE, so it might just be a window manger problem or something to do with compositing, since as far as I know Cinnamon won;t work with Compiz or Compton.

I'm adding this update logged into Cinnamon and the text is still fine.  However, that doesn't solve all my problems.  I'm back to:

*     No mouswheel scrolling to change workspaces
*     No separate wallpaper for each desktop

So a little hunting around for something else and I found a setting that adds a desktop scroll area to the left and right edges of the screen.  I had just installed Docky so I could use its workspace swithcer applet, but now I can use the green area on the left and right.

That green shaded marker area can be adjusted for width or hidden.  It also works even if a window is under it, which means Docky will be staying in place to reserve space.  That way the scroll bar will still be accessible in a full screen window.


It lives in   System Settings > Extensions



And here's where you set it up.  There will be a warning about it not being compatible with Cinnamon.  I suppose now I will have to copy this into a new post about the Gigabyte BRiX and Mint 18.1 Cinnamon.








Mint 18.1 XFCE Single Click to open desktop icons

One of my last little annoyances about Mint with XFCE has been solved.

I like to use a single click to open files or activate icons.  In most Linux distributions this function is enabled and disabled in the file manager, and because the primary file manager also controls the desktop, changing to single click to open files in the file manager, makes that available on the desktop.

But not in XFCE.  So I was messing around planning to change the default icons that are displayed on the desktop.

I right clicked the desktop, chose the Desktop Settings Option, then Icons -  and there it was staring at me.

[]   Single click to activate items.

So now I have one more little thing sorted out.  Searching the net suggested that double clicking to open a folder or file on the desktop is just something we just have to learn to live with.  but it is not - now I know where to find it.

Gigabyte BRiX BACE-3150 Revisited Micro SD now works



NOTE !!  UPDATED  2017 March 2nd
Micro SD is now also working in Mint 17.3  See special post.

In July 2016 I wrote about the little Gigabyte BRiX  BACE-3150.  At the time it was brand new to me and I was running Linux Mint 17.3 KDE.  Yesterday I wrote about changing the operating system to Mint 18.1 and how I had to give up KDE because the latest version of KDE is loaded with flaws.


Today I would like to go over a few of my likes and dislikes about living with the BRiX because several people have asked me whether such a low powered computer is able to do any 'real' work.

So, first things first.  The BRiX BACE-3150 is really only a higher end intel Atom processor.  A Celeron.  But it happens to have a quad core and 64 bit architecture.  Considering that my 'desktop' computer experience goes back to Z80 processors running cp/m, and I remember just how much work we could do with those, I'm pretty impressed with the BRiX for general purpose computing.

What I am not impressed with is the lack of graphics support in Linux.  But the CPU?  With Mint 18.1 offering an intel microcode driver, the BRiX does most work really well.  I do a lot of work with graphics and a fair bit of video work.  It handles video editing nicely, although it could be faster.  But of course, if you want more power in a small package, there are other BRiX models with full blown i7 or AMD processors.

The graphics problem is rather petty.  It has to do with screen redraw when scrolling a page.  And it did not happen in Mint 17.3.  I first noticed it when I tested Mint 18.1 KDE and now it is in Mint 18.1 XFCE.



For example in Blogger as I type this, every now and then a line of text has little horizontal lines through it.  But the moment I scroll at all, it is crystal clear again.  I couldn't even take a screen shot of the problem because that also clears it,so here's a photo from my phone.   You can see on the line where it says BRiX.  As soon as the mouse takes focus or if I do anything that involves the screen - it goes away.  Again, this is only in Mint 18.1, it doesn't happen in 17.3.

UPDATE:
I'm not sure if this fixes the problem above, but so far it seems to reduce it.

While trying various settings I found 'Synchronise drawing to the vertical blank'.  Now I'm not sure what this means and I will need to do some searching, but there seems to be some improvement.  Below is a screen shot.  It is in Settings, Window Manager Tweaks, and is the third item in the dialog below.



As far as playing video goes, there's no problem.  No tearing, nothing.  It is just screen redraws and it doesn't matter if compositing is on or off, or if it is using Compiz or Compton, it works fine except for the little horizontal lines in the page.  It appears it could also be something to do with rendering for mouse focus and I'm still playing with settings.

Booting back into the Mint 17.3 partition, and that problem is gone.  But there are other reasons to put up with the graphics glitch that outweigh the small annoyance.

I am beginning to wonder if it is related to my use of HDMI output.  This model BRiX has only HDMI and VGA, where later models seem to have HDMI and Mini DP.

So, back in Mint 18.1 XFCE and the biggest change is that the BRiX Micro SD reader which had not worked before now works great.  That, along with the 4 USB 3.0 ports gave the BRiX the lead over every other PC I looked at when I needed a replacement work horse.  A trip to Harvey Norman and JB HiFi recently showed almost every computer and notebook still only had one USB 3.0 and the rest USB 2.0.

With cheap Micro SD cards up to 128GB and also 2TB USB hard drives under $100, the Brix is open to lots of storage and fast file transfers.  So the huge number of USB 3.0 ports and the fast Micro Sd are handy, but what is WRONG with the BRiX?

The fan is noisy.  I have heard that and it is partly true if you live in a hot climate as I do.  I set the fan to its high setting because the temperature in the room where the BRiX operates is over 30 degrees Celsius and I work it hard.  But it is far less intrusive than the other computers I use.

It sometimes goes to a weird greenish yellow screen for no apparent reason when running the HDMI output and refuses to come back to the desktop.

I found that plugging in the VGA cable (connected to the same monitor or TV) then switching to that display would let me log out.  And sometimes it wouldn't.  It was more noticeable when coming back to HDMI after using the TV/Monitor as a TV for a while.  Often the only way to get it working again was to kill the power and boot from scratch.

Since moving to Mint 18.1 I find a CTRL ALT DEL will bring up the log in screen and I can simply log in again.  I just realised that at present I have the VGA and HDMI cables both plugged into the BRiX, so I have to test the idea without the VGA plugged in tomorrow.

There's really not much else to complain about.  Just that funny lines thing on some screens / pages and the losing output on HDMI.

I get more work done in the BRiX than on any of my other devices and I am probably happier with it than with any single computer I remember buying, bearing in mind that I always buy simple low end computers with a view to working them hard then replacing them after three years.

Linux Mint 18.1 XFCE and Gigabyte BRIX BACE-3150


Well, after discovering that Linux running KDE Plasma 5 is definitely and apparently permanently crippled, even on my more powerful systems, I decided that I will have to move the little Celeron powered BRIX away from KDE if I want to begin using mint 18.x.  So here I am back in Linux Mint XFCE after many years.  Because  the BACE-3150 is really not much more than a later version of a notebook Atom, it seemed like a good idea.

XFCE used to be good.  It was fast, clean and although it limited me in some things I wanted to do, it worked.  These days it works even better.  But it still limits some of the little things I like and simply doesn't have some of the polish of KDE.  but it also doesn't have the things I dislike about Gnome, Mate, Cinnamon etc.  And, typical of Clem and his dilligent hard working team - it is very stable.  Which reminds me - it is time for another donation.

Over the years when I have changed my computers to a new operating system, and once I establish that it is working nicely, I donate to support the effort.  It is no different than paying the licence fee for Windows or Mac when you buy a computer with those operating systems on it anyway.  I have also donated to the developers of the software I use most on these computers.

So I spent a few days messing with XFCE and I still can't get past the file manager limitations.  I tweaked Thunar but that was no good, so I installed Nautilus, PCFM, Double commander.  Now as I type this I have Dolphin installing so at least I might get my KIM system back again.  

Ok, Installing Dolphin was a lost cause.  So I am still left without a decent File Manager.  So far there's nothing I can do about that, but there are other things I really do love about XFCE that almost make up for the lousy file managers.  Honestly, Dolphin once it it tweaked with KIM is the main reason I use KDE.

One of my favourite XFCE things is that I can still customise the panel and menus easily.  Another is being able to scroll through my desktops using the mousewheel (mentioned in a previous post), and of course it is easier to see what desktop I am on since I can have a different wallpaper on each desktop.

Now, something I never used for a long time in KDE, and consequently never thought I would miss, is 'Activities.  But it will not be too hard to get used to doing without them again.  My short time trying to use Plasma 5 forced me to use Activities INSTEAD of work spaces, so I suppose I'm not giving up much.

Another interesting thing is that after I loaded the intel CPU driver microcode that showed up as an option in the repositories I suddenly had even better performance.  Unfortunately there's still no onboard graphics driver fix, but the CPU stuff flies.

And I'm not sure if it was just in the Mint 18.1 kernel, or if it was something to do with the microcode also, but the BRIX micro SD card reader now works.  Yet another good reason to upgrade from Mint 17.3 KDE.

I do miss some of the little tweaks I had made to KDE.  I am used to double clicking the tittie bar to roll up or roll down the window, and scrolling the mousewheel on the title bar to change the opacity of a window.

In XFCE, I have the scroll on the title bar rolling the window up or down instead.  And the reality is, while it was 'cute' to be able to change the opacity of a window, I rarely used it.  I do however roll windows up and down (sometimes called shade/unshade) frequently if I wad to tidy up a desktop or access an open file manager window.

UDDATE:
I have discovered that I can in fact double click on the title bar to shade a window.  So while I can't change opacity of the window with the mousewheel, I have two methods to shade/roll up a window to see or access what is behind it.

LibreOffice suddenly very slow in Linux Mint 17 and 18

I have been having serious problems with LibreOffice taking forever to scroll pages and move or resize graphics recently.  I checked Google and found other people have been having this problem for a long time.

Suggestions to fix it range from making sure Hardware Acceleration is ENABLED or DISABLED, Enabling or Disabling GL, messing with memory and anti-aliasing.

None of that worked for me.  So I wondered if it was something to do with the version.  Had some update messed with things?

I downloaded the last version 4.x.x  but when I checked in Synaptic to remove version 5.3, I saw another version 1:5.1.4-0ubuntu1.  So once I removed version 5.3 I simply installed the other version in the repository.

Problem solved for now.  Everything is running smoothly again.  Now, I'm running what is apparently version 1:5.1.4-0ubuntu1, but help calls it Version: 5.1.4.2
Build ID: 1:5.1.4-0ubuntu1

Whatever it is, it seems to be working fine.  So there must be some sort of drama with Libre 5.3.

Now I have ot fixed in Mint 18.1 XFCE the next step will be to see if the same thing works in my old faithful Mint 17.3  KDE.


Mint 18 XFCE change desktops with mouse scroll wheel

Recently Mint 18.1 was released, so I decided it might be time to try KDE with Plasma 5 again.

It didn't take long to discover that this latest Plasma workspace is still almost useless on Linux with certain hardware.  It leaves mouse trails all over the screen when certain programs are open, especially the Dolphin file manager, and has a number of other annoyances.  As mentioned in a previous post, I like to use different wallpapers on my workspaces and this is still absent from the latest Plasma.  So while I was being frustrated I decided to visit an old friend.

XFCE has been around for a long time, and I used to use it on things like low powered computer and netbooks.  Since the current multimedia computer is a Gigabyte BRiX BACE3150, I thought I might have a look at Mint 18.1 XFCE edition, just for fun.

Now the BRiX has some shortcomings, and one of them is the Intel HD Graphics on board.  I'm not impressed that in some operations in one of my most frequently used programs, Libreoffice Draw, I cannot work with graphics.  Almost every other program works fine.  GIMP and Darktable, even Openshot for video editing.  But LibreOffice cannot resize a simple 150kb PNG logo.

So now we come to the subject of this post.  With XFCE I can have my different wallpaper on each desktop.  But with that I am so used to simply scrolling my mouse wheel on a blank area of the desktop to switch desktops.

Now installing a pager in the panel allows mousewheel switching, but that doesn;t solve the problem.

Luckily there is something called 'Window Manager Tweaks' built into Mint 18.1 XFCE.


And under the 'Workspaces' tab, right at the top is what we are looking for.

Now something else I discovered years ago is that I hate having to change the size of an open window to give myself a spot to scroll on.  That sort of defeats the purpose.

So I got into the habit of creating a little panel on the right (if you are left handed you'd probably do it on the other side) and when a window is maximized, it leaves a little strip down that side for me to scroll on.

When I am in KDE I have a few odd launchers on that panel, but this install of XFCE only has the bare panel.  Here's how it looks.  The small vertical grey rectangle to the right of 'bookmarks'.


Before I found the 'Tweak' settings I had a Workplace Switcher'  in that little side panel, and had the panel positioned about half way down the right hands side where I could conveniently scroll on it with the mouse.
That would still work for anyone with a desktop that doesn'e allow desktop scrolling to change workspaces.

Fix GTK fonts in KDE - A Better Way

Recently I managed to setup KDE to make fonts in a few of my non-KDE programs at least readable.  But it was a hit and miss approach.  Since then I have found a much cleaner solution that is in the Linux Mint repository and might be in most other repos.  Unlike my previous effort, this method is pretty consistent across my various GTK programs.

If you are running KDE4.x Plasma, either search in Synaptic for kde-gtk-config, and install it, or open a terminal and:

sudo apt-get install kde-gtk-config

Open:
System Settings > Application Appearance.

In the left pane choose GTK.

Among other things you can adjust the font.
Mine was some weird Ubutu font with a size of 14.  Changing it to the font and same size I use in my KDE-qt Programs worked perfectly and seems to stick across things like Synaptic, Chrome, GIMP  and Geeqie among others.

If you modified things according to my previous post you might also have to go to Fonts while you are in System Settings and drop Force Fonts DPI back to 96 or turn it off.

If you did sudo systemsettings and made the changes as root you will have to go back there and turn off Force fonts DPI or at least reduce it to the default (96).

no public key available for the following key IDs: 1397BC53640DB551 Mint 17.3 2016 December 16

 I have had a problem trying to refresh Mint Update and finally some searching has shown that apparently it was caused by some stupidity by Google.  Stupidity seems to be a regular feature of both Google and Facebook these days, but luckily people manage to find ways to fix their stuff ups from time to time.

In this case the refresh was throwing up an error message:
no public key available for the following key IDs:
1397BC53640DB551.

The fix appears to be to open a terminal and run the following command:

wget -qO- https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

Then do a refresh.

KDE - Easily FIX tiny fonts in Synaptic Package Manager

NOTE  This post has been updated with a better method on 11th January 2017.  The new method will work with KDE4.x, but requires installing a package that might not be in your repositories.  If it is, it makes life much simpler.

KDE is a lovely desktop to work with.  Correction, KDE 4.x is a lovely desktop to work with.  Plasma 5.x is so screwed up that all we can hope for is that someone decides to fork Plasma 4.x and maintain it.

In the mean time, for users of Mint 17.x KDE, one frustration is that as soon as we go into a non KDE program we end up with tiny little fonts on the screen.  In the image above, Synaptic Package Manager is showing with a Font Size of 9, and no amount of fiddling with font settings in KDE System Settigns, > Application Settings > Appearance > Fonts, will fix it.  Likewise, changing the settings in preferences in Synaptic makes no difference at all.

There are lots of posts from frustrated KDE users wanting a way to get Synaptic to have fonts consistent with the rest of their KDE desktop.  And despite all the weird and wonderful config file suggestions and deleting and reinstalling components, on my system one thing worked perfectly.  changing the fonts as ROOT.

Open a Terminal and use the command:     kdesudo  systemsettings

That will open the settings dialog.  In my case, as ROOT, the fonts were all Size 9.  My normal system fonts are about size 14 or 16 on my large LED monitors.



Find 'Fonts' in the left pane and choose Adjust All Fonts, and select a suitable size.  I chose Size 16 to be compatible with the screen I am using.



Choose Apply, and check the difference in Synaptic.
If Synaptic displays lines overlapping each other vertically, go back and put a tick in 'Force Fonts DPI', then Apply and restart Synaptic.  That should fix it.

Here's the Before and After - Font Size 9 as default, and Font Size 16 after.  Much nicer to work with.



Since posting this I have found a partial solution to some font problems in a few other non-KDE programs.

if you have a hidden file in yoiur home folder called        .gtkrc-2.0      you can edit it.  If it is not there. create it and make sure the settings below are in it.  Adjust the font size from 12 to whatever works for you.  Reboot the system then open some non KDE programs and see if it works.
