Encountered two system freezes this afternoon within about 10 minutes. One time the screen froze but the sound kept playing.
Keyboard, mouse all not functioning. Had to hard reset with power button.
Could be graphics related as I was using VLC media player and was resizing the window.
Unfortunately, I only have the log file from the last reboot for some reason (when I do: journalctl --since=today)
Log file starts from 13:07 today.
When I do: last|grep boot
I can see the following boot's:
reboot system boot 5.7.7-arch1-1 Sat Jul 25 13:07 still running
reboot system boot 5.7.7-arch1-1 Sat Jul 25 13:01 still running
reboot system boot 5.7.7-arch1-1 Sat Jul 25 12:59 still running
I read here and here that the /etc/systemd/journald.conf setting Storage= needs to be set to persistent in order for logs to be kept longer term.
Mine was set to volatile. I've changed this now and restarted service, so hopefully there will be some 'Critical' errors in the journalctl next time it freezes.
BTW, I'm using:
Namib Linux Version: 19.01
Arch version: 1.4
KDE Plasma version: 5.19.3
KDE Framewords version: 5.71.0
Qt version: 5.15.0
Kernel: 5.7.7.arch1-1
I think there is a newer kernel than this (5.7.10.arch1-1). I should update to the latest kernel and see if the issue comes up again.
It's a known bug in Kernel 5.7.2-arch1-1.
Don't know if it was fixed with Kernel 5.7.10.arch1-1.
But some have reported that they had to switch to 'Linux archlinux 5.4.53-1-lts' to resolve it.
