The problem is, that the GUI freezes (sometimes already in GDM, sometimes later in the desktop, for instance when I navigate in the settings app). Once the freeze happened, I'm unable to switch to a text console, because mouse input and keyboard input are no longer accepted. How can I find "the frozen process" if I'm locked out from the computer? The only way out of the freeze is power cycle. And no, it is not my hardware - kernel vmlinuz-6.5.0-45-generic works seamlessly.
The freeze doesn't happen when I manage to switch to a text console in the very early stages of the desktop start. But if I switch back to the GUI in order to provoke the freeze, the freeze happens after some seconds and I'm locked out. I cannot investigate anything after the freeze. I will try to connect to the box via ssh after the freeze. -- 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.
