Thanks, Daniel for the answer. 1. I think I was mistaken, when I set the resolution of the external monitor to 2560 ⨉ 1440 while the lid is closed, it persists after opening and closing the lid, both in X11 and Wayland. So I think the behaviour is like that and there is no bug after all.
2. I don't use fractional scaling because the performance is degraded in X11, and fractional scaling doesn't even work in Wayland. In Wayland, scaling values stay 100%, 200%, 300% and so on, nothing changes whether fractional scaling is on or off. I attached a screenshot that shows fractional scaling in Wayland. It shows the scaling values, and that gnome-control-center is scaled to 200% but Firefox and Goldendict (Qt) are not. ** Attachment added: "Wayland_fractional_scaling.png" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1888800/+attachment/5395526/+files/Wayland_fractional_scaling.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1888800 Title: Resolution of external monitor goes back to its default resolution when laptop lid is closed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1888800/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
