[Bug 1878421] Re: (If external monitor connected) Hang on boot while showing ubuntu boot screen with animation

[frank]

hi, hang seems to be fixed with nosplash-option, but i still cannot use
external monitor in Xorg...it looks now like its basicly working (see
cursor), but i cannot see any windows...they are opened on external
screen (i use internal screen as primary right to my external, so this
is also wrong) and they are not shown...i see only cursor...no
background-image, no windows (dragging them to external shows cursor,
but not the window).

also noticed bug in login-screen (my external monitor is 4k and fullhd
internal)...if my workstation is locked, i see upper left quarter of my
background-image on internal display and no login-window...so it's hard
to login

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
