Bug Description
Hi, I have recently swapped out an NV card for AMD one and with no other changes this has started appearing.
After I leave my PC idle for +- 5-10 minutes I come back to a blank screen, and if I switch to VT/tty and back then it just opens lightdm/
When I switch to VT/tty, I can see my old session/
If I switch to VT/tty and back without leaving my machine idle, then it's working as expected.
