Public bug reported: Since wayland will be the default with 17.10 it might be important to have it ready for multiple monitor support. I have the latest updates installed and I am on the artful channel.
SETUP: HiDPI internal screen running at 2160x1440 (Surface Pro 3) External FullHD HDMI monitor running at 1920x1080 Since the upgrade to the latest GNOME 3.26, wayland got activated again. I was running X before. Usually, I set my internal screen off and only work with the external monitor if plugged in. ISSUE: With wayland active for both GDM and GNOME there is actually two issues: 1. I am able to configure my desired settings in the display settings as usual (=turn off internal screen and use only external monitor). But since the latest update this setting is not remembered after a new login. It can only remember the "mirror" or "join displays" options but not the "single display" option. Very annoying to reconfigure this after every login. Before the update to the new GNOME settings look I was at least able to have this setting remembered (even with wayland). However, even back then it was not perfect since the internal screen was not completely turned off (black but with light on). After manually setting the displays again the screen was turned off but not after a login. This is a wayland related issue since it is not reproducable with X. 2. GDM is always on the internal screen and simply does not match and respect your GNOME config. I tried several ways to configure this: sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config - does not work since wayland ignores this config file. I tried to using shell scripts executed at startup with xrandr. But xrandr does not work with wayland, too. So this is also not a solution. FIX: I don't know how to configure GDM with wayland. I am willing to test things out but have no further ideas and am relatively new to Linux/Ubuntu. Thanks for any help.
