When an external display is connected to my laptop, running Ubuntu
22.04, the display is detected and I am sent to the login screen. After
logging in again, the display is not running, although the primary
laptop display works fine. The external monitor is looking for
connection in that moment, which it never founds.
The bug is tested on two Samsung monitors: S24R350FHUXEN and S22F350FHU.
