Starting sddm works fine, starting my normal session crashes or freezes
FreeBSD.
I can find no error messages after a reboot.
I found out, that I can start xterm or emacs (exwm) without problems,
xrandr works with external screen, but once I start anything more
demanding (I guess demanding of the GPU) everything freezes or FreeBSD
even reboots.
âDemandingâ means even simple things like qterminal. I tried firefox an
d
blender and then I had it with the reboots and didnât try anything else.
xedit works fine :)
I have nothing in the logs, I have no idea where to look or how to debug
this.
Any ideas, tipps, help greatly apreciated.
FreeBSD Developers Handbook Chapter 10: Kernel Debugging
https://docs.freebsd.org/en/books/developers-handbook/kerneldebug/
Running stable, kernel dumps may already be enabled, look in /var/crash
By enabling a kernel dump when it panics (dumpdev="AUTO" in rc.conf) the
kernel core is saved to swap space, then on reboot gets copied to
dumpdir (/var/crash) where you can then use kgdb (from devel/gdb) to get
a stack trace to find where the panic happened.
drm-*-kmod probably needs a rebuild. Likely a data structure changed. In my
experience a simple rebuild of the port solves 90% of drm-*-kmod crash
problems.
Hi Cy,
sorry I didn't mention that, but I did rebuild drm-kmod, I actually do it after
every new kernel build, just to be on the safe side.
I switched my swap to non-encrypted and will look if I can get any information
from the kernel dump tomorrow.
Oh, and it's on a Thinkpad X1 Yoga 3rd gen, I just noticed I didn't mention
this.
It may be worth trying drm-515-kmod as some MFC that works with 515 and
not 510 may have been committed. Linux-KPI commits are the usual
suspects.
I use drm-515 with 14-CURRENT.
drm-515 with 14-CURRENT works fine, but there is a breakage in drm-510 on
stable/13. I built it after kernel update today, but it doesn't load:
linker_load_file: /boot/modules/radeonkms.ko - unsupported file type. Loading
old module of course leads to immediate panic. I am investigating it.
