** Description changed: Hello I have a very peculiar situation. I have a PC with RTX3060Ti and Ubuntu 21.10 (dual-boot). Once I log-in to Ubuntu, only one of my 2 monitors is working properly, the other turns itself on, but has a black screen and goes to sleep mode after couple of seconds. Both monitors are detected by the Nvidia Settings. Furthermore I can drag apps to/from the blacked- out monitor as if it worked correctly. The weird thing is that if I switch to a different source on the blacked-out monitor and then return to the original source (the one connected to the PC), the monitor is detected and works as it should: 1) Switching the source to a different one - Ubuntu detects that there is only one monitor, all apps that were 'displayed' on a blacked-out monitor go to the other, single monitor 2) Switching back to the original source - Ubuntu detects both monitors and they both work correctly. - I'm using Nvidia 510 Drivers. Tried older ones and Xorg drivers but no - luck. Changing the outputs on GPU doesn't work either. I'm ready to - provide any diagnostic information, just tell me what you need. It's - really annoying. + I'm using Nvidia 510 Drivers. Tried older ones and Xorg drivers but no luck. Changing the outputs on GPU doesn't work either.
