Public bug reported: 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1965611 Title: Ubuntu 21.10 + RTX3060Ti - second display black after login, works again after toggling the sources Status in linux package in Ubuntu: New Bug description: Hello I have a very peculiar situation.
