Thanks for the bug report. I can see bug 1968040 in the log, but that also shows that atomic KMS is in use whereas this bug should be about non-atomic KMS failing (MUTTER_DEBUG_FORCE_KMS_MODE=simple).
Please check for any crashes using https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment Please also collect a system log from when MUTTER_DEBUG_FORCE_KMS_MODE=simple was in use. If it was the previous boot then run: journalctl -b-1 > prevboot.txt and attach the resulting text file here. ** Summary changed: - Laptop screen can't be turned on after suspension or locking + Can't log in anymore after setting MUTTER_DEBUG_FORCE_KMS_MODE=simple ** Tags added: hybrid i915 multigpu nvidia ** Package changed: gnome-shell (Ubuntu) => mutter (Ubuntu) ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell 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.
