[Dell XPS 13 9340] [i915] After recent update, screen is corrupted level with mouse pointer

[John Sturdy]

I accepted a "restart to install changes" request box yesterday, and my screen immediately started to show corruption on the scan lines which the mouse pointer has recently been on.

The corruption only happens on the built-in laptop display; external monitors are not affected.

I have tried a reboot, and an "apt-get update; apt-get dist-upgrade" followed by a reboot, and neither of these had any effect.

The machine is a Dell XPS13, running Ubuntu 24.04 LTS.

Thanks for the bug report. Please add kernel parameter i915.enable_psr=0 to avoid such problems. You can do so in /etc/default/grub by changing:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

Then run:

  sudo update-grub

and reboot.

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

Many thanks for the quick reply --- that worked fine :-)

@John,

Could you try mainline kernel to check if it's reproduced:
https://kernel.ubuntu.com/mainline/v6.10-rc4/

I think it's a regression from commit:
1d395ab43e6bf drm/i915/display: Increase number of fast wake precharge pulses
e6b076d508d48 drm/i915/psr: Calculate IO wake and fast wake lines for DISPLAY_VER < 12
307476565ef6e drm/i915/psr: Improve fast and IO wake lines calculation

If mainline kernel can reproduce it, we should let Intel know.
