GPU, drivers, and screen setup

I have a laptop with an integrated and discrete GPU:

# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-HX GT1 [UHD Graphics 770] (rev 0c)
01:00.0 VGA compatible controller: NVIDIA Corporation GA107GLM [RTX A1000 Laptop GPU] (rev a1)

• Running a 3840x1600 monitor on DP over thunderbolt connected to the discrete GPU using nvidia driver
• on startup i disable the laptop screen and configure my monitor:

   xrandr --output eDP-1-1 --off
   xrandr --output DP-0 --auto
   xrandr --setprovideroutputsource modesetting NVIDIA-0
   nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}"

# Set the log level. Possible values are:
#  "trace", "debug", "info", "warn", "error"

# Set the log file.
# If *--log-file* is never specified, logs will be written to stderr.

Steps of reproduction

It seem to happen quite consistently, my suspicion is that it crases right before my system goes into sleep mode, or X decides to go to sleep mode and turns off the display.

Expected behavior

No crashes

Current Behavior

picom crashes present in coredump list

[yshui]

can you xtrace the compositor as it crashes? and post the logs here.

[svenrademakers]

Yes! I will be back behind my pc next week. I will see if i can get a trace of it
