Bug Description

Since updating into 23.10, when I change my build-in display from 2880x1800 (16:10) at 90Hz to any other resolution, it turns the screen black and unable to use.

The only resolution that works is the predefined one.

This bug wasn't present on the previous release, 23.04.

Changing the resolution on the external screen works fine. The problem is with the build-in display.

This issue is fixed in 6.6-rc3: 2de19022c5d7 ("drm/amd/display: fix the ability to use lower resolution modes on eDP")

It's backported to stable 6.5.6 as 79aec38ba852 ("drm/amd/display: fix the ability to use lower resolution modes on eDP").

Canonical needs to pull the fix into their kernel.

Is the release expected soon please? (The bug does not affect only those who proactively modified resolution and so know what got wrong, but also those who had it modified and upgraded from Lunar to Mantic – these people have no clue what the issue is. I almost left Ubuntu because the blank screen was not something I could live with and I could not find a solution. Early release might help other people. Edit: No intent to push on you, just trying to bring some motivation. :-D Thanks for your hard work.)
