I have 2 monitors, a 1920x1080 monitor and a 3840x2160 monitor.
They are both connected to the on-board graphics (Intel HD Graphics 530).
For a while I've been trying to get scaling to work properly on only the 4k monitor.
While the solution I found works for the scaling, it seems to have introduced a new problem.
After a while when using Chromium, when nothing special seems to be happening, ie. not navigating away, no notifications, etc., the X server crashes.
The DM I'm using is GDM and the shell gnome-shell (GNOME on Xorg, not wayland).
After running these commands, the crash seems to happen after a random amount of time:
Note: The first one may not be relevant, but it's one of the commands i used for the scaling.
# luna @ Luna in ~ [22:55:50]
$ gsettings set org.gnome.desktop.interface scaling-factor 2
# luna @ Luna in ~ [22:56:50]
$ xrandr --output HDMI3 --scale 2x2 --pos 0x0 --panning 3840x2160 --output DP1 --pos 3840x0I also noticed that if I don't use `--panning 3840x2160 `, the X server crashes as soon as I start Chromium.
In the output of `sudo journalctl -x` I found the following messages:
