Bug description:
  Hi,

  i try to use external monitor on my dell G5 2019 (5590). works on
  ubuntu 18.4 (after reboot) using prime-select nvidia.

  did this on 20.4 (prime-select + reboot because logoff/login again
  still don't work) and it hang on boot while showing ubuntu bootscreen
  with animation (not stopped, but also response to esc-key to show
  terminal-output) on the monitor (need to switch off). booted again
  where monitor is configured to other input, boot works, i see it in
  preferences dialog as second monitor, but if i configure input on
  monitor i have no signal..

  
  anything i can try?

  regards Frank
