Issues with GNOME Display Settings in Ubuntu 24.04 beta

[Kostya Vasilyev]

Two issues with GNOME Display Settings since upgrading to Ubuntu 24.04 beta

1 - I am unable to select Fractional Scaling and set it to 150%.

The Fractional Scaling checkbox appears to do nothing - 1) selecting it does not enable the Apply button 2) does not update the list of supported scaling factors to include fractional values.

2 - There is a ghost display

I have one display plugged into a NVDIA 4080, using proprietary driver. There is a ghost "Unknown Display" in Display Settings at resolution 1024x768.

Expectations:

1 - I should be able to enable Fractional Scaling and set it to 150%

2 - There should be no ghost "Unknown Display"
