Yes fractional scaling is a "construction site" in that it's still an experimental feature. Only Ubuntu exposes the GUI to enable it. Everyone else has to:
gsettings set org.gnome.mutter experimental-features ... As for this bug, it's probably, usually, caused by some part of the detected displays changing and so the system reverts to defaults as if you've just plugged in a new monitor. To prove that we will need to compare the output of 'xrandr' before and after the bug happens. Please also do a comparison in 'Ubuntu on Xorg' and tell us if the bug occurs there too. -- 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/1928073 Title: Display settings don't persist across reboot / sleep Status in gnome-control-center package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: My setup: Dell XPS 13 7390 2-in-1, internal display (3840x2400) First external monitor: Dell 24" running at 2560x1440 connected via USB-C/Thunderbolt Second external monitor: same, connected to the first monitor via DP Scale of the internal display set to 200%, fractional scaling on Scale of the external displays set to 100%, fractional scaling on What I expect: Settings persist across reboot / sleep / resume. What I observe: Settings for external monitors are back to 200% scale, fractional scaling off. Looks like there's a problem detecting the external monitors/resolutions in time.
