Ever since I installed 22.04 (Lenovo Thinkpad T480, Nvidia GeForce MX150, Linux kernel 5.15) in April I've been having episodes of my laptop display becoming garbled seemingly at random, every 1-2 days or so on average. It starts at the bottom of the screen and sweeps upwards until most of the screen is covered, then after a few seconds everything goes black. There may have been a faint buzzing sound once as well but hopefully I misheard.
Overall the system stays responsive, logging out with Ctrl+Alt+Delete or locking the screen works and restores the screen to normal. When the corruption starts while an external monitor is plugged in, only the laptop display is affected. I was lucky enough to get a photo of it as it happened last week: Laptop display mid-corruption
So far I've tried:
- Moving from nouveau NVIDIA drivers to proprietary (nvidia-driver-510)
- Switching between the Xorg and Wayland version on the login screen
I used to run Mint on this laptop a few years ago and I remember having had screen issues related to modesetting but wasn't able to find anything about it related to my current problems.
Thanks in advance and if any more info is needed I'd be glad to give it :)
Edit: I've ruled out hardware issues as I'm dual-booting Windows and haven't had any issues since the glitches started.
Edit 2: Going to list other things I've tried since posting here:
- running "sudo nvidia-xconfig"
Edit 3: I've asked the same question on Ubuntu Launchpad with some promising results, link here.
