A laptop's internal screen counts as one of the monitors. 1. Connected monitors to system which don't have same resolution. 2. Open the GNOME Settings app (gnome-control-center) 3. On the left sidebar, click Displays to switch to the Display panel 4. Switch to mirror mode 3. gnome-control-center won't crash [Where problems could occur] It only modified the code related to mirror mode in Displays panel. For KK and LL check variable (best_mode) before using it. For Jammy, modified the way to find cloning mode and check the variable (best_mode) . The second patch already included in gnome-42. The risk will be low. [Other info] Two Merge Request are related 1. Check best_mode exist before adding flag (https://gitlab.gnome.org/GNOME/gnome-control-center/-/merge_requests/1835) 2. Use virtual clone modes when mirroring (https://gitlab.gnome.org/GNOME/gnome-control-center/-/merge_requests/1376) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/2026228/+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
