Hello, I have run into problems with my display. Problem appeared with my upgrading to Ubuntu 24.04 (Previous 23.10 run without this problem). I have AMD based PC with nVidia 3060 and one display connected via DisplayPort. Problem is that if I manually turn off display (physically by display power button) every time if I try to get back to PC my session is logged off. I didnt hear any beeping that could be PC self-reseting. I have also tried pulling DP cable while running and plugging it back and I find out that it takes couple of seconds to recognize but if fails, shows "something went wrong" and logs off session. Also in Ubuntu display setting it show two displays which one is unknown and I have not second display.
In BIOS i have disabled any iGPU and I would like to mention that in 23.10 I have no problems.
I have tried drivers 535 and 550 with secure boot off and on without any different behavior.
Thanks for any suggestions
Jan
