@yukine8 @vinegere Sorry for corrupting your system.
If it is possible, could you help to test a different approach proposed by [1]? Here is the test package: https://launchpad.net/~kchsieh/+archive/ubuntu/verification libpciaccess 0.17-3ubuntu0.24.04.3~oem1 Thanks, [1] https://gitlab.freedesktop.org/xorg/lib/libpciaccess/-/merge_requests/38 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libpciaccess in Ubuntu. https://bugs.launchpad.net/bugs/2115574 Title: Upgrade of libpciaccess0 to 0.17-3ubuntu0.25.04.1 causes black screen on boot with AMD Radeon GPU Status in libpciaccess package in Ubuntu: Invalid Status in libpciaccess source package in Noble: Fix Committed Status in libpciaccess source package in Plucky: Fix Committed Status in libpciaccess source package in Questing: Invalid Bug description: [ Impact ] This is fixing a regression introduced by LP: #2111684. After the upgrade, the system fails to boot into the graphical user interface. This was reported here, and LP: #2115605 and LP: #2115598, and also in forums like https://forums.linuxmint.com/viewtopic.php?t=448655. One report says that the login prompt (gdm) is there, and it's just the monitor that is off. Blindly typing the credentials seems to work and get into the GUI, provided the credentials are correct. In all the reported cases, reverting to the previous version of this package fixed the problem. [ Test Plan ] Update to the proposed package. Reboot, and confirm that the GUI login prompt shows up as normal, and allows login to the system. [ Where problems could occur ] This update is an exact revert of LP: #2111684. It's not expected for the revert to introduce new problems, since it doesn't involve any postinst actions or something else that would not be idempotent. One obvious regression, though, is that bug LP: #2111684 will be reintroduced to those systems that were affected by it. [ Original Description ] 1) The release of Ubuntu you are using: Kubuntu 25.04 "Plucky Puffin" 2) The version of the package you are using: The issue is caused by upgrading libpciaccess0. Working version: 0.17-3build1 Problematic version: 0.17-3ubuntu0.25.04.1 3) What you expected to happen: After a standard system upgrade via sudo apt upgrade and a reboot, I expected the system to boot normally into the Kubuntu Plasma desktop environment, just as it did before the upgrade. 4. What happened instead: After the upgrade, the system fails to boot into the graphical user interface. The boot process shows the Kubuntu logo, but immediately after, the screen turns black. My primary monitor shows a black screen, and my secondary monitor loses its signal entirely. Troubleshooting and Workaround: Booting into Recovery Mode works. Restoring a system snapshot (via Timeshift) to the state before the apt upgrade resolves the issue, and the system boots normally again. By isolating the packages, I have confirmed that the problem is specifically caused by the upgrade of the libpciaccess0 package. The issue is consistently reproducible by upgrading only this package. The current workaround is to prevent the package from being upgraded by using the command: sudo apt-mark hold libpciaccess0. With this package held back, all other system updates can be installed without causing the boot issue. This issue seems to be related to how the new version of libpciaccess0 interacts with the AMD Radeon graphics driver during the system's startup sequence. My hardware includes an AMD Radeon GPU. My GPU is an AMD Radeon RX 7700 XT.
