-> I'm using 2 monitors (1 internal and 1 external). -> The nvidia GPU is enabled, monitor is plugged to it through HDMI. -> The CPU usage of GNOME Shell spikes. There is no writed at the same time (the led doesn't blink) and no other process seems to run for it. The memory usages seems stable though. See log attachement which is a snapshot of CPU and MEM usage every second (you can see at the end a freeze for multiple seconds corresponding to GNOME Shell CPU spike). CPU spike can go up to 200%. -> I've run a wayland session for a period of time and didn't notice any issues. So seems Xorg specific.
Note that this is a regression as I'm running Xorg + drm modeset for a year or so without experiencing that previously. ** Changed in: mutter (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1823301 Title: [nvidia] Shell hangs up at random times when using nvidia- drm.modeset=1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1823301/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
