Do you have a better solution? If I change the HDMI display to -2560x-360 it doesn't work either. Now there is space to the bottom and right of the laptop display (captured in screenshot) and the external monitor is not actually at that position either, it's more like -2560x-180 (not sure if negative values are even supported.) I've attached a screenshot with no external display connected.
Like I said, this is a new problem. ** Attachment added: "Screenshot from 2019-03-07 07-56-35.png" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1818829/+attachment/5244436/+files/Screenshot%20from%202019-03-07%2007-56-35.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1818829 Title: Disconnected monitors act as present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1818829/+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
