I just switched to the non-atomic KMS (MUTTER_DEBUG_FORCE_KMS_MODE=simple). My computer turned to black and turned unusable. I wasn't able to Crtl+Alt+F3 and switch to the terminal at all. Hopefully, I was able to change the /etc/environment to the default with a live CD and was able to boot again to my computer normally.
I can't see any crashes related to this (the last crash was yesterday, and this was a few minutes ago) in /var/crash. I can upload, though, the system log from the previous boot. ** Attachment added: "prevboot.txt" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1994000/+attachment/5626377/+files/prevboot.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1994000 Title: Can't log in anymore after setting MUTTER_DEBUG_FORCE_KMS_MODE=simple To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1994000/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
