KDE freezes randomly + graphical glitches

[Akezhar]

I've been having this issue lately where the desktop locks up but the PC keeps functioning, I can keep listening to whatever audio was playing and friends on voip can hear me, another strange thing is that sometimes it's not a full freeze, in some instances I can keep scrolling through chats and browser windows but trying to open new windows or pulling up the menu doesn't work, other times it's a complete freeze and nothing works.
The only way I can get the desktop back is by CTRL+ALT+BACKSPACE and logging back in.

Another, perhaps unrelated, problem is that I'm having random glitches in the UI like in the following image:

These glitches don't happen all the time and rebooting can fix it.

I have no clue on how to fix this so any suggestion is welcome.

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

and post some more information so we can see what's really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies...

P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you're using, which CPU/GPU you have, ...

[Fabby]

That's a good start, thanks. When it happens again, REISUB your machine and do a:

sudo journalctl --system --boot=-1 > /tmp/Journal.txt

and upload /tmp/Journal.txt here so we can have an in-depth look of what's happening.

[Akezhar]

After a couple days without problems I got the graphical glitch again this morning, I have a txt file as instructed but I can only upload images on the forum, where should I upload the file?

In the mean time I was scrolling through the journal in the terminal and saw a bunch of red messages towards the end of the file

As you have an AMD dGPU, their drivers are built into the kernel, so:

• Log off

• Switch to TTY2 by pressing Ctrl+Alt+F2

• Log in there

• Execute:

  sudo mhwd-kernel --install linux419
  sudo mhwd-kernel --install linux56-rt
  

• to ensure grub is showing, execute:

   sudo nano --backup /etc/default/grub
  

• Change (or add?) the following 3 lines:

  GRUB_TIMEOUT=3
  #GRUB_HIDDEN_TIMEOUT=0
  #GRUB_TIMEOUT_STYLE=hidden
  

  (3 or higher is fine, add the # before the lines above if those lines are present)

• Ctrl+X Y Enter to save if there is anything to save

• If you did save, execute:

   sudo update-grub 
  

• Reboot

• Go to grub's Advanced options

• Choose these kernels one by one and try them out one by one and see if that helps.

If it doesn't, these are the available kernels:

• linux316
• linux414
• linux419
• linux44
• linux49
• linux54
• linux55
• linux56
• linux57
• linux54-rt
• linux56-rt

[Akezhar]

After trying a bunch of different kernels without success I've decided to make a new install of the OS, and the problems seem to be gone.

[Fabby]

You should have mentioned that this didn't help as it could also have been a user artefact instead of a system artefact and then creating a new user would have been sufficient instead of a full re-install.

Next time!
