Random logout in Buster/KDE

Postby NFT5 » 2019-08-05 10:52

I recently installed a clean Buster and chose the Plasma desktop.

I've been experiencing random logouts, usually when I click something with the mouse. That it's logging out, not restarting, leads me to think that it's display server related, but I'm not sure and can't find any consistent errors that would point to a single problem.

Google returns a few instances of similar problems, usually on Mint (not that that's relevant, I think) but no consistent answers.

So, I'm looking for some ideas on where to look to solve the problem.

Code: Select all
chris@BOSSDESK:~$ inxi
CPU: 6-Core AMD FX-6300 (-MCP-) speed/min/max: 1405/1400/3500 MHz Kernel: 4.19.0-5-amd64 x86_64 Up: N/A
Mem: 929.4/7945.1 MiB (11.7%) Storage: 1.58 TiB (43.5% used) Procs: 242 Shell: bash 5.0.3 inxi: 3.0.32


These CPUs do run hot but I have a big cooler fitted and it usually sits around 59C. Weather is cool here and other sensor temperatures range 18-26C. System gets cleaned every few months. Pretty sure it isn't a hardware problem anyway. No problem on this machine running Debian 8 or 9, MATE and XFCE respectively.

I am afraid, that you would find help in e.g. forum.KDE.org: Workspace with higher probability than in this forum, because it seems to be KDE specific to me...

Thanks ruwolf. I was hoping to avoid joining yet another forum, but we'll see what responses I get here. There are quite a few using the KDE desktop.

Check the systemd journal for errors and perhaps install the systemd-coredump package and see if coredumpctl(1) can find anything left by the killed X server — the output probably won't be useful to you (or me) but the developers may be able to get something from it.
