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 Desktop Packages, 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 Status in mutter package in Ubuntu: Incomplete Bug description: My laptop is running a Hybrid Nvidia RTX3060 + Intel i5 11400h graphics. After installing the Nvidia drivers and with Wayland (this doesn't happen with Xorg), once the screen is turned off (for example, by locking the screen or suspending the computer, it cannot be turned on. This is a behavior similarish to the one in bug 1968040 (IDK if that one was also triggered by a screen lock, this one gets triggered inmediately after turning off the screen for whatever reason). In 22.04, I solved it quite easily by setting MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0. As suggested in that ticket, I set this time MUTTER_DEBUG_FORCE_KMS_MODE=simple. I unfortunately cannot tell whether this would solve my issues because, when I reboot my computer with that variable, I simply cannot log in into my account. I type my password as usual (the login screen works perfectly, though) and then, once submited, the output is a black screen (LCD is on, though) and nothing shows up after.
