Contents of /sys/class/drm/card0/error file associated with GPU HANG
1) Unlike when I encountered the bug, this time I did not see the following
messages when I reproduced the bug (and captured error log) on
4.13.0-21-generic.
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
2) When I collected the above error, all of the following were true.
a) GRUB_GFXPAYLOAD_LINUX was not specified
b) No external monitor cable were plugged into the laptop
c) "Intel" GPU was selected in Nvidia X Server Settings
3) There was no GPU HANG message at boot time in configurations !a && b, !a &&
b, and !a && !b. IIRC, content was displayed on the integrated display when
GRUB_GFXPAYLOAD_LINUX=1920*1080.
4) System76 mentioned that the HDMI port is not connected to iGPU on my Oryx
Pro laptop. [xrandr does not list HDMI port if "Intel" GPU was selected.] (I
am interested in a software based solution to verify HDMI-GPU connectivity.]</pre>
