Title:
  [nvidia] Screen turns off when trying to set some fractional scaling
  values

Status in mutter package in Ubuntu:
  Fix Released
Status in nvidia-graphics-drivers package in Ubuntu:
  Won't Fix
Status in mutter source package in Focal:
  Fix Committed
Status in nvidia-graphics-drivers source package in Focal:
  Won't Fix

Bug description:
  [ Impact ]

  When the nvidia driver is installed, the screen turns off when trying
  to set some fractional scaling values like 150%. And it stays off even
  after rebooting and logging in again.

  And from ssh I can see there's no current mode set anymore (just like
  in bug 1869750):

  $ xrandr
  Screen 0: minimum 8 x 8, current 960 x 600, maximum 16384 x 16384
  DVI-I-0 disconnected (normal left inverted right x axis y axis)
  DVI-I-1 disconnected (normal left inverted right x axis y axis)
  DP-0 disconnected (normal left inverted right x axis y axis)
  DP-1 connected primary (normal left inverted right x axis y axis)
     1920x1200     59.95 +  59.88

  [ Test case ]

  In a Nvidia system:
  - From g-c-c enable fractional scaling
  - Set all the available fractional scaling values and ensure they work
    + In any case the screen should be turned off

  [ Regression potential ]

  Wrong screen size is set and panning might be enabled.
