Title: On high resolution modes, after screen resume from power saving, the display configuration gets lost, and sometimes Gnome crashes Status in gnome-shell package in Ubuntu: Incomplete Bug description: This is a follow-up issue from https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers- common/+bug/2075525, and some of the information from the earlier issue may apply here. I have configured the host screen with two monitors extending the desktop. They are both configured at 3840x2160 @ 60Hz, scale 200%, fractional scaling: no. I'm using a HDMI 2.1 cable on the one monitor, and a DisplayPort cable on the other monitor. My graphics card lacks a second display port connector, so I can not try if the problem would persist with two DisplayPort cables. After a period of inactivity, the screens get blanked as configured. When I move the mouse and the screens unblank, the display configuration is changed. I have observed different behavior of the changed display configuration: - most commonly, the displays change into mirror mode instead of joined mode. - sometimes, a third, small display appears on one of the sides. - sometimes, the second monitor stays blank - sometimes, Gnome crashes I confirm that I have ubuntu-drivers-common:amd64/noble-updates 1:0.9.7.6ubuntu3.1, so this should have the issue fixed? Attached is an excerpt from syslog, from around the time then I unlocked the display coming back from suspend, until the Gnome crash. System information: No LSB modules are available.
