Comment 7 for bug 1841826

I have this problem as well on ubuntu 20.10 on a Thinkpad T14 with integrated Geforce MX330 graphics. My laptop is closed and docked via a thunderbolt 3 dock to a single external monitor.

I have tried the fix proposed here: https://askubuntu.com/questions/1083720/ubuntu-goes-suspended-after-login-if-lid-is-closed/1239573#1239573 to no avail.
