I had a similar problem and my workaround using the CLI to configure the secondary screen position might work for you too. The issue is https://bugs.kde.org/show_bug.cgi?id=507702 The relevant part for you: The two commands that enabled and correctly positioned the secondary screen were ``` kscreen-doctor output.HDMI-A-1.enable kscreen-doctor output.HDMI-A-1.position.1920,0 ``` The position should be corrected depending on the primary screen resolution and the `HDMI-A-1` should be changed to whatever the port for the secondary screen is.
Thanks for the bug report. This looks to be the same as bug 507702. I'm going to merge this report into the other once. *** This bug has been marked as a duplicate of bug 507702 ***
