Ubuntu – Display settings not saved across sessions when using fractional scaling


I have a pc with:

  • Nvidia gtx1080
  • two 4k monitors
  • Ubuntu 19.10
  • nvidia xserver installed

I changed the scaling and order of monitors in Ubuntu Display settings.

However when I reboot or logout/login the display settings reset and i have to set them all over again each time.

How to fix this?


I have narrowed down the bug further.

The settings are not persisted when fractional scaling is used and set.

So with fractional scaling enabled:

If I change the scaling, none of the display settings are persisted across sessions and 100% of settings are reset upon reboot.

If I dont change the scaling (leaving it at 100%), but change other display settings, like the position of monitors, they are indeed persisted.
