I have the same problem. I can set my laptop display to FHD down from 4K to match my external monitor, but as soon as I click on "scale 100%" button the apply button disappears and I get "Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Logical monitor scales must be identical" on the console.
A workaround that works in the meantime is to use arandr, arrange your screens, and apply any changes - this will reset scale back to 1 and gnome display control panel works again. Arandr bottom snap can make both displays overlap, bear that in mind if you get the gnome panel repeated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
