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_

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.
