I'm still not seeing any other crash reports like this. These log messages might be related to the issue:
Window manager warning: Impossible to resize screen at size 3840x2160, error id 8: BadMatch (invalid parameter attributes) Window manager warning: Impossible to resize screen at size 7680x2160, error id 8: BadMatch (invalid parameter attributes) and they seem to originate from an Ubuntu patch 'x11-Add-support-for- fractional-scaling-using-Randr.patch'. But since you're apparently not using scaling on any displays, there's nothing I can suggest turning off there... Looking at monitors.xml.txt shows some things that might need fixing though: 1. The HDMI connected monitor is sometimes detected at 50Hz instead of 60Hz. If you didn't do this on purpose then it suggests you need a higher grade HDMI cable for more reliable behaviour. 2. There is an old "Unknown" monitor config. That was likely from bug 2060268. My suggestions: 1. Delete ~/.config/monitors.xml and log in again. Then reconfigure your displays. 2. If the problem still isn't fixed then upgrade the HDMI cable and repeat step 1. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2081199 Title: [nvidia] 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: New 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.
