Hello, In my case, the person upgraded GDM and linux-firmware, then turned off his computer. At the next boot, he had a black screen.
When I checked the kernel logs, I saw issues with "amdgpu" and suspected a link with bug 2128883: I installed the previous version of linux-firmware and rebooted, but the black screen was still there. I then tried to downgrade GDM3 and its lib, but the previous version was no longer in the repo. Because I was in command line, I didn't try to download the previous version from LP, and instead, I removed the "Automatic Login" entries from "/etc/gdm3/custom.conf" and rebooted. This fixed the issue. The laptop owner never used the terminal, I don't see why MUTTER_DEBUG_FORCE_EGL_STREAM would be set to 1. If you think it is needed, I can ask to get access to the laptop again to reproduce the issue and get more logs. Hopefully the issue is a combination of "auto login" + specific HW or custom config, so it doesn't affect too many people. (Also, if I was not there, I'm sure this person would not have been able to report the issue here → what I mean is that maybe it affects more people that we think.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2128840 Title: Automatic Login with gdm3 amd64 46.2-1ubuntu1~24.04.3 [335 kB] is broken.
