Xorg crash log
Hello there,
I have a Razer Blade 14" (2016), which has an integrated Intel graphics and a
dedicated NVIDIA GTX 1060M GPU to which the HDMI port is physically routed.
I am using the Intel and Nouveau driver to drive 3 screens: the integrated
3200x1800 panel on eDP1, an AOC 25" 2560x1600 screen through a USB-C to HDMI
adapter on DP1, and another AOC 25" 2560x1600 screen through the dedicated HDMI
port on HDMI-1-2.
I manage to randomly get them to work: most of the time, as soon as I plug in
the HDMI cable, the X server crashes in loop. I attached the log, I suspect the
total resolution is bigger than what is accepted by the Intel GPU or something,
even though in Ubuntu I forced the integrated panel resolution to 2560x1600 to
get below 8192x8192, it tries to assign a total surface of 8320x1800.
Is there some way to force the integrated panel to a lower resolution? I am
using my laptop primarily at work, and attached to external screens, so I
couldn't care less if it was running at 3200x1800 or 2560x1600.
Regardless, there's a crash that needs to be fixed I guess :)
Here's my Xorg.conf (required so that xrandr lists the Nvidia adapter and
detects the HDMI screen):
Section "ServerFlags"
Option "IgnoreABI" "1"
EndSection
Section "Device"
Identifier "Nvidia card"
Driver "nouveau"
EndSection
I attached the Xorg.0.log of the crash.
