Title:
[nvidia] GUI Scaling does not work with multiple monitors
Status in mutter package in Ubuntu:
New
Status in nvidia-graphics-drivers-440 package in Ubuntu:
New
Bug description:
When changing the GUI scaling factor on a multiple monitor setup the
monitors all just go blank and then revert to the previous values.
Changing the scaling factor manually in the config file does not work
either, it causes all monitors to go blank as well.
I observed that it is trying to set a mode "null", here is the line from the
Xorg log:
`NVIDIA(0): Setting mode "NULL"`
I have initially noticed this after upgrading from Ubuntu 19.10 to
20.04 and my screens would all be just blank after the system has
booted up. I had to delete the monitor configuration files manually
via SSH to get a screen output in xorg again.
