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.
  Description:  Ubuntu 24.04.1 LTS
  Release:      24.04
