Hello, i have Lenovo machine with Quadro P1000 Mobile video card running on Ubuntu 20.04 with lowlatency kernel. There are random problems happening with OS login - the system occasionally (50% of cases) ends up with black screen after login. What should i try to solve this? nvidia-bug-report.log.…

FIXED it by setting HandleLidSwitchDocked=ignore in /etc/systemd/logind.conf

Did you create the log right after running into the black screen?

nvidia-bug-report.log.gz (379.3 KB) Here is the log i did just now after boot happened on 5 or 6 attempt

It’s a bit odd, the second the Xserver is stopping after login, the system is going into suspend. Do you have the lid closed and your users’s energy settings set to do so?

https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1897185 Please check if setting kernel parameter nvidia-drm.modeset=1 helps with that.

Exactly, I need to boot Thinkpad P52 docked with closed lid Best regards Ilya Shadrin

Unfortunately it doesn’t help :(

Then use gnome-tweaks to disable the suspend on lid close.

gnome-tweaks doesn’t helped as well. Seems like there should be a lower level fix over multiple places to make it really work 22 release might be a hope :( Best regards Ilya Shadrin
