Title:
  Update of libpciaccess causes switched-off monitor after boot

Status in libpciaccess package in Ubuntu:
  Confirmed

Bug description:
  Hello,
  the update of version 0.17-3ubuntu0.24.04.1 of libpciaccess causes that the screen is switched-off/disconnected while the login screen is show.
  I'm using Linux Mint 22.1 Cinnamon. If this update gets installed, the next time booting the system looks like this:

  1. The Linux boot screen gets shown
  2. The screen gets black and switches off. "blind" login still is possible.
  3. If logged in the screen switches on again and I can use my system as always

  I did reset my system multiple times with timeshift and now I'm sure it is the update of libpciaccess that causes this problem.
  Other people have the same problem: https://forums.linuxmint.com/viewtopic.php?t=448655
  I already did report the bug at https://gitlab.freedesktop.org/xorg/lib/libpciaccess/-/issues/24 but there they said I should report it here because the patch from Ubuntu causes the problem.

  Some details to my system:

  Kernel: 6.8.0-62-generic arch: x86_64 bits: 64 compiler: gcc v: 13.3.0 clocksource: tsc
  Desktop: Cinnamon v: 6.4.8 tk: GTK v: 3.24.41 wm: Muffin v: 6.4.1 vt: 7 dm: LightDM v: 1.30.0
  Distro: Linux Mint 22.1 Xia base: Ubuntu 24.04 noble
  Graphics:
  Device-2: AMD Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] vendor: Tul / PowerColor

  I hope this is the right place for the issue. Please let me know if more information is needed.
  Unfortunately "ubuntu-bug libpciaccess" does not work at Linux Mint.

  Best Regards
  Christian
