Screen freezes randomly, but can access tty

The past few weeks, I’ve had the screen freeze randomly. During this time:

  • The mouse pointer + trackpad works, it even changes from pointer to cursor, etc. based on where it is
  • Nothing is clickable/draggable
  • Not sure what causes it because sometimes it happens when Alt+Tabing, sometimes when opening new windows of apps
  • I can access tty with ctrl+alt+F2 when it freezes and use it normally
  • killall plasmashell and DISPLAY=:0 kstart5 plasmashell works in the sense that there aren’t any errors, but there is no change at all on the first screen. The open applications are still frozen, like a picture.
  • The only way to get out of this (without a restart) is systemctl restart sddm which kills the session.

So I’m curious what’s the middle ground between restarting plasmashell and sddm? Or how do you find out what the problem is?

journalctl logs don’t seem helpful (the freeze happened ~10:43, I switched to tty2 as soon as it froze):

❯ journalctl --no-hostname -b -1 --priority=7 --no-pager --since "10:40:00" --until "10:50:00"

Can you check to run that if it causes the issue?

$ sudo btrfs qgroup show /
❯ sudo btrfs qgroup show /
ERROR: can't list qgroups: quotas not enabled

(exit code 1)

And no, it doesn’t freeze screen.

That is ok, You have disabled quota. It has nothing to do with your issue.
Something is wrong in your KDE environment.

I had a similar issue before, moving the window to the edge of the screen (scaling the window to half the screen) the screen froze. Later, I found that there was no such problem with creating a new user, so I created a new user and transferred the data to solve this problem.

I have a lot of things in this user and would prefer not to move everything. There’s no specific trigger afaik, since I’m doing different things when it freezes.

Hi, i had this issue for some time, always some seconds after starting plasma.

I replaced the .cache folder in my user folder by a link to /tmp (tmpfs folder) i renamed .cache, then the cache is flushed everytime i stop computer (for now i didn’t see any problem doing that…, just using much more memory with cache).

I have no more freeze (may be just delete .cache content may work, but when i checked i had very old things from software i don’t use anymore in that folder that’s why i decided to go with a volatile cache ^_^b).

I hope it may help…

I’ll try clearing cache and see if it freezes. Since it’s irregular (more than once a day to once a week), it’ll be difficult to tell if it’s fixed. Will report back if it repeats.
