Flickering windows


I installed KDE Plasma a week ago, tried it and left.  Then yesterday I decided to play more seriously with it. I updated it to 5.9 and tried to use it.

It had a lot of problems and took me hours to solve them all.  Just to find another issue that wasn’t critical but certainly annoying.  But it was too late at night, so I cleaned the computer using Bleachbit and turned it off.

Today I turned it on and everything was working fine, so I assumed that some temporary file, cache or whatever was the cause.  I used my computer normally and turned it off when I had to go out.  So far so good.

And then it happened again.


The Problem

Windows seemed to flicker and twinkle, often refusing to disappear when one would close them.  Also minimise/maximise caused them to tremble and leave a ghost of window over the desktop.  Often I had to click twice or more on the  “Show desktop”  button to get them to disappear.  It was driving me insane when someone from the Fedora Telegram group sent a suggestion to fix it.


The Solution

The solution to this weird and apparently random problem was quite simple.  If you go to System Settings => Display & Monitor => Compositor  you’ll find some options including the rendering backend.  Set it to OpenGL 3.1  and apply.  That should be enough to fix the  “bug”.  If the problem seems to come back, change the rendering from Accurate to Smooth  (or any other that works for you).


Technical details

Laptop: Dell Latitude E6500, with Nvidia video card, 500GB hard disk, 4GB RAM and Dual Core processor.  System:  Fedora 25 Workstation with KDE Plasma 5.9.


Hope this is useful, thanks for reading!

Problems with USB ports


If you’re experiencing problems with USB ports, ABRT is throwing system error messages or you something odd related to USB during the boot, here you have two ways to find out what’s going on.  Once you know there are two possible ways to sort it out. Let’s see.



If the error, or at least the error message, just happened, you can run this command:

journalctl -xe

and this will show you what just happened.

If you only notice the problem time later, you can run this another command:


and search for errors related to USB ports.


Looking for a solution

Now you know what happened you can search for it Google with a simple search, or in wiki pages or books, or in forums, groups and mailing lists.  If it’s not urgent, always try the Google Search first.



Write down the solutions that worked in a note and keep it handy.  That will save you time and headache in the next opportunity an error occurs.


Hope this is useful for you, thanks for reading!

Fedora is in Telegram


Fedora is everywhere and its community has many ways to stay in touch.  But there’s one that has been growing at a fast pace in the last months:  Telegram.

For those who already have this service, just check the Fedora wiki to see the groups and channels available.  The international group is now over 800 members.

For those who haven’t this service yet, can download Telegram from here and start using it just with a phone number and a username.  There are versions for iOS, Android, Windows and Linux.

If you need anything else, just send me a message!  I’m Kohane  🙂

Now Windows is Linux friendly


Before switching discs in my laptop I prepared two DVD  (I have no spare USB sticks or SD memories),  one with Windows 8.1 and one with Fedora 25 Workstation.  Much to my dismay I later come to learn that Fedora doesn’t boot from optical devices like CD & DVD, so I used the only Linux I had, an OpenSuSe USB stick I’ve got from OpenRheinRuhr.

Now… for years we were all told  “Install Windows first because Linux recognises Win partitions but the viceversa doesn’t apply”.  So I installed Windows first.  And it did recognised the existing partitioning including, yes, Linux volumes.  I wanted to start over so I just deleted everything and assign it to Windows.

But it’s not just that.  With a small app, you can use your Linux partitions from Windows as if they were… well, other partitions.  Office recognises ODT formats and opens them without errors or complains  (it used to make a fuss years ago).  And… oh, this is my favourite!  Windows doesn’t label Linux/Open Source stuff as virus as it always did.  And visiting Linux pages doesn’t trigger a lot of alarms in your system saying it’s dangerous and evil and you should leave that site to never come back.

So if you’re planning to make a dual boot of your computer, go ahead, Windows won’t get in your way anymore.

Mysterious Evolution


I’m a Fedora Workstation user for some months now.  Never an issue, so much that despite I’m no friend of mail clients I adopted this one for my Fedora stuff.  But some days ago my calendar/email app Evolution started to show a big warning.



And now it started to show yet another even bigger warning.

Right, right.


I’m puzzled about the sudden change.  Any thoughts?
