Thanks. I can see the variable was honoured this time: Aug 23 12:42:32 stella gnome-shell[1104]: Added device '/dev/dri/card1' (i915) using non-atomic mode setting. Aug 23 12:42:33 stella kernel: intel ips 0000:00:1f.6: i915 driver attached, reenabling gpu turbo
Strange that kernel message always seems to be present around the same time. I think the next step is to add: MUTTER_DEBUG=kms so we can maybe see why the screen is freezing. Also try MUTTER_DEBUG=kms without MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0. ** Summary changed: - Gnome desktop freeze after kernel update + Screen freezes with kernel 6.8 (also "i915 driver attached, reenabling gpu turbo"), while kernel 6.5 still works -- 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.
