I set up and save the two configurations separately in gnome-control- center, but they are not applied when switching modes with Super+P (or with the dedicated key) or when switching modes in gnome-control-center, the settings don't persist.
The settings are saved in ~/.config/monitors.xml when setting up and saving the configuration in gnome-control-center, but they are not applied when switching with Super+P or when switching modes in gnome- control-center, the settings don't persist. Another way to see the bug is to save a mode configuration in gnome- control-center then switch to the same mode using Super+P by pressing Super+P many times without selecting a different mode, the settings will be lost. See the attached screencast. ** Attachment added: "Monitor-conf.webm" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1905084/+attachment/5437640/+files/Monitor-conf.webm -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1905084 Title: Fractional scaling of external monitor and monitor positioning are lost when switching between single- and extended-display modes using the keyboard Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: Steps to reproduce: 0. Attach an external monitor to the laptop 1. Set the external monitor as the primary monitor 2. Change the fractional scaling of the external monitor to 150% and change the positioning of the built-in monitor to the desired positioning 3. Switch to the single-display mode using the keyboard → 4. The fractional scaling of the external monitor changes to 100% (this could be the intended behaviour and not a bug) 5. Change again the fractional scaling of the external monitor to 150% 6. Switch to the extended-display mode using the keyboard → 7. The fractional scaling of the external monitor changes to 100% (this is a bug, it should persist) → 8. The positioning of the built-in monitor changes to the default (this is a bug, it should persist) ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: mutter 3.36.6-1ubuntu0.20.04.2 ProcVersionSignature: Ubuntu 5.4.0-54.60-generic 5.4.65 Uname: Linux 5.4.0-54-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.12 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Fri Nov 20 20:04:26 2020 InstallationDate: Installed on 2020-04-26 (208 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash SourcePackage: mutter UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1905084/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
