I stand corrected: fractional scaling on/off persists. The scale (100%) does not, it jumps back to 200% and my Chrome windows that were on the external screens are back on the internal display.
The latter was already reported as https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1927948 I am using Wayland yes, which I guess is default in 21.04. Sorry for this off-topic comment, but I'm a bit frustrated: What I'm also missing is instructions how to get things working nicely in 21.04 with Wayland, this still looks like a massive WIP / construction site. Don't get me wrong, ppl with external monitors and HiDPI internal screen are probably a minority, so I appreciate not everything can be fully tested by devs/QA before release. I've tried to follow instructions here: https://wiki.archlinux.org/title/HiDPI#Multiple_external_monitors ...but only some of them help. I would appreciate Ubuntu documentation on how to get Chrome, Thunderbird, Skype, Signal Desktop, Telegram, ... working nicely with this setup. I will take some time to dig deeper and report appropriate bugs against respective packages, if appropriate. -- 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.
