Hi, I've been running with this since it hit the tree and it has fixed a major issue for me: an external HDMI output was marked 'disconnected' only a few minutes after being connected. The output worked fine, but I presume X was notified that something changed and my window manager would restrict the area for popups and drop down menus to the main screen, as in they would only appear on the panel of the laptop, regardless of where the actual window was. So huge thanks for that! In the meantime (somewhere around Mesa update and a backout), another issue got fixed. If a test 60fps video would've been displayed on the panel, a visible tearing artefact would be visible in the upper portion of the screen. And now it's gone. Thanks Jonathan and Mark for your work on this, it's greatly appreciated! My hardware is an X1 Carbon 2017 (Kaby Lake) with a WQHD (2560x1440) panel and a 1920x1080 external monitor. Cheers, Mike
