Please try these two kernels separately: https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/2022-07-08/amd64/ https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.18.11/amd64/ When testing each you need to download all the .deb files and install them together: sudo dpkg -i *.deb ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1981559 Title: [amdgpu] Gnome Freezes When Second Display is Turned Off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1981559/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
