I installed driver version 460.39 and encountered what I assume is the same bug, the only usable scaling was 100% and 200% with the other fractional scaling options 'zoomed' in slightly so the right-hand side of the desktop was cut-off.
I did however find a workaround on AU https://askubuntu.com/a/1321851/8570 that might help identify the problem. Open nvidia settings with root privileges: sudo nvidia-settings In PRIME profiles change *Performance* to *On-Demand* Restart system Verify that fractional scaling is working again Reopen nvidia-settings as above and change *On-Demand* back to *Performance* Restart system Verify that fractional scaling is still working -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
