apport information
** Description changed:
I’m using a laptop with NVIDIA GPU and only external screen. The laptop
screen is disabled. When I try to enable the laptop screen with xrandr, I get:
$ xrandr --output eDP-1-1 --auto --left-of DP-2
xrandr: Configure crtc 4 failed
Reproduction steps:
* Connect an external display to a laptop
* Disable laptop display
* Reboot
* Enable laptop display with `xrandr` command
Expected behavior:
Laptop display is enabled
Actual behavior:
Laptop display is not enabled
Additional information:
Problem is not appearing on kernel version `5.4.0-66-generic`
