With a fresh install of Ubuntu 20.04 (downloaded ISO and installed one day after release of 20.04) fractional scaling with the Nvidia driver was working fine. It was still working fine after several updates, however, I think with the update to version 440 of the driver, fractional scaling stopped working correctly. I have configured the system to use another graphics adapter just to get the fractional scaling I need, but the performance difference is quite evident and I would prefer to use the Nvidia adapter.
I am searching on the internet for ways to revert to a previous version of the Nvidia driver. If anyone has done this successfully then I would really appreciate the steps required for this. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% Status in gnome-control-center package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: Procedure used: 1.
