Same issue here with Thinkpad P13s Gen 2 (AMD) with 23.10 installed just moments ago
I'm also unable to install the fixes on a fresh installation: sudo apt install -t mantic-proposed mutter Reading package lists... Done E: The value 'mantic-proposed' is invalid for APT::Default-Release as such a release is not available in the sources sudo apt install mutter/mantic-proposed Reading package lists... Done Building dependency tree... Done Reading state information... Done Package mutter is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: mutter-common-bin E: Release 'mantic-proposed' for 'mutter' was not found Did I miss something? => mutter-common-bin is already the newest version (45.0-3ubuntu3). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2034619 Title: [amdgpu] gnome-shell gets SIGKILL'd when lock screen or under heavy load in Wayland Status in Linux: New Status in Mutter: Fix Released Status in X.Org X server: Fix Released Status in linux package in Ubuntu: Triaged Status in mutter package in Ubuntu: Fix Released Status in linux source package in Mantic: Triaged Status in mutter source package in Mantic: Fix Committed Bug description: [ Impact ] gnome-shell gets unceremoniously SIGKILLed on some Ryzen systems, sometimes when the screen locks, sometimes when launching particular apps. [ Workaround ] Add this to /etc/environment: MUTTER_DEBUG_KMS_THREAD_TYPE=user and then reboot. [ Test Plan ] Not all Ryzen systems (including one I just purchased) are able to reproduce the bug. We have no choice but to leave final verification to the community. Anyone affected should try locking their screen and verify they are not instantly returned to the login screen. [ Where problems could occur ] Anywhere in frame scheduling and particularly for mouse cursor movement since that's what the real-time thread exists to optimize. [ Original Description ] I have this issue on Ubuntu 23.10. Lock screen works only with an external monitor connected. Otherwise the session is ended and the user is logged out and brought to the gdm screen. All works in xorg.
