Title:
[nvidia] Screen turns off when trying to set some fractional scaling
values
Status in mutter package in Ubuntu:

Status in nvidia-graphics-drivers package in Ubuntu:

Status in mutter source package in Focal:

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.
