gnome-shell 42.9 Wayland sessions fail to start on Intel 12th gen or later if running 5.15/5.17 kernels (Failed to lock front buffer on /dev/dri/cardN: drmModeAddFB2WithModifiers failed: Invalid argument)

Thanks for the bug report. It appears the kernel '5.15.0-1034-intel-iotg' is too old for the integrated GPU of 'i7-1260P'.

Did you install that kernel manually? Or perhaps install some IOT image instead of Ubuntu Desktop? I would have expected a fresh install of Ubuntu Desktop 22.04.2 to come with a newer kernel:

  https://ubuntu.com/download/desktop

so please install that instead.

Status changed to 'Confirmed' because the bug affects multiple users.

Nevermind. This bug is affecting regular Ubuntu Desktop too, for those running the original 22.04 release. It shouldn't happen if you're using 22.04.2 though because that has a new enough kernel to support the hardware, in theory.

Suggested workarounds:

* Add MUTTER_DEBUG_USE_KMS_MODIFIERS=0 to /etc/environment

* sudo apt install linux-generic-hwe-22.04

It's a regression introduced in mutter 42.9 by Intel:

https://gitlab.gnome.org/GNOME/mutter/-/commit/1fd96e30f5f8a61d70d51f9012112e01818161a7

Although they would probably argue it's not a regression so long as you have a new enough kernel. Since we don't always have a new enough kernel in jammy we probably need to revert that commit.

Fix proposed: https://salsa.debian.org/gnome-team/mutter/-/merge_requests/100

I'm setting the importance to Critical per #6 at https://wiki.ubuntu.com/StableReleaseUpdates#Procedure

In the test plan, can you also please confirm it keeps working with the current and upcoming HWE kernels for jammy?

Hi Daniel,

I reinstalled today my ADL-P PC with Ubuntu Desktop 22.04.02.
And this is not reproduced with -generic kernel.

Hi Andreas,

Will try to check new packages in next days.
Thanks for all.

I think "This was a regression introduced by Intel in 42.9!" should be removed from the changelog. It's not something I wrote in the patch or in the merge proposal.

Hello Andreas,

I saw the same error on a 13th Gen Intel(R) Core(TM) i7-1370PE using the IOT release of jammy desktop.

I can confirm that installing mutter from jammy-proposed fixed the issue on my system.

Hi Andreas,

I reinstalled today my PC with Ubuntu Desktop IOT.
And i use latest packages from proposed repository.

This issue is now resolved.

My PC now running this:

ii mutter-common 42.9-0ubuntu3 all shared files for the Mutter window manager

Thank you Daniel for your support.

A good day.

Jammy verification done in comment #14.

But I'm blocking proposed because the changelog needs fixing per comment #12, and agreed within the desktop team.

Status changed to 'Confirmed' because the bug affects multiple users.
