Package: gdm3 Version: 3.22.3-2 Severity: important Dear Maintainer,
I'm using a laptop (Dell XPS 15 9550) connected to a docking station (Dell WD15). The docking station is connected to a Monitor with multiple inputs through a DisplayPort cable. I also have a second computer connected to the same monitor on a different DisplayPort input. When I suspend the laptop and the other computer is running, the monitor automatically switches input to the one of the running computer. When I later resume the laptop and switch the monitor input port to the one connected to the laptop all I can see is a blank screen. Opening the laptop lid and trying to use the internal display doesn't work either. The only thing that I can do is reboot the machine the hard way, through the power button. I would expect the session being able to rediscover the external monitor or at least switch to the internal display.
