Not quite; with X the screens flicker a couple of times, somehow change resolution temporarily, but then come back with the original settings.
With the X case (don't remember checking the wayland one), when I start the resolution modification, I see things like this when starting gnome- control-center from the console: (gnome-control-center:15810): display-cc-panel-WARNING **: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Logical monitor scales must be identical ...and the Apply button does not show up. When I change the external monitor to 100% scaling, the Apply button appears and is enabled, then clicking on it gives this stuff on console while the flickering etc occurs: (gnome-control-center:15810): display-cc-panel-WARNING **: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying (gnome-control-center:15810): display-cc-panel-WARNING **: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "org.gnome.Mutter.DisplayConfig" does not exist ...and then, after that, finally this on the console: (gnome-control-center:15810): display-cc-panel-WARNING **: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: The requested configuration is based on stale information -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1722708 Title: Crash when setting laptop display resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1722708/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
