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-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
