Thanks. You can remove MUTTER_DEBUG=kms now. Those logs look perfectly well behaved, as in my suspicion that page flips might be getting lost was wrong and nothing is getting lost. This means something else is freezing. So I can only suggest killing the frozen process like:
sudo killall -USR1 gnome-shell and then reporting it as a crash via ubuntu-bug for the robots to process. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.8 in Ubuntu. https://bugs.launchpad.net/bugs/2077265 Title: Screen freezes with kernel 6.8 (also "i915 driver attached, reenabling gpu turbo"), while kernel 6.5 still works Status in linux-hwe-6.8 package in Ubuntu: Incomplete Bug description: After a kernel update (on 2024-08-14, if I remember correctly), the Gnome desktop freezes, always. This happens sometimes already on the login screen (mouse pointer frozen, no keyboard input accepted). Sometimes it happens a few seconds or a few minutes after login. No further input possible. No change to a text console possible. When I disconnect the USB-mouse and reconnect it, the mouse LED remains dark. Seems that USB is frozen too. This happens with kernel: vmlinuz-6.8.0-40-generic When I boot the previous kernel: vmlinuz-6.5.0-45-generic, no freezes occur and all works well. I managed to switch to a text console before the freeze happened. The attached files were created in a text console as root and then transferred to a different computer in order to report the bug.
