I recently switched my x86_64 GuixSD laptop to use SDDM, so I could try out GNOME on Wayland. It mostly works, but there are still a few problems: * Even after logging in, SDDM is still visibly running within xorg-server on VT 7, while Wayland is running on VT 8. If you switch back to VT 7, you can see the login screen still there, with the clock showing the time that you logged in instead of the current time. I'm not sure if there are security implications to this, but it's certainly a waste of system resources. * SDDM is based on Qt, so it substantially increases the closure size of the system, as well as memory usage since SDDM and Xorg-server continues to run in another VT during your entire session. * The "Sound" panel of the GNOME settings is non-functional. Whenever I try to change anything at all in that panel, it crashes. * Startup notification for several GNOME programs is broken, e.g. GNOME Terminal, Files (Nautilus), Videos (Totem), and possibly other. When I launch any of those programs, although the program immediately starts up, GNOME Shell doesn't seem to realize this, and for quite some time the spinner continues to indicate that the application is starting up, and it doesn't show up in the Alt-Tab application switcher. If you switch to another application, you cannot switch back to it via Alt-Tab. * As far as I know, we haven't yet themed SDDM to include our beautiful GuixSD login screen artwork. It would be a shame to lose that by default. On the other hand, I'm pleased to report that under Wayland, tearing no longer occurs during video playback, scrolling, etc. Anyway, it's very exciting to see progress on this, but I'm reluctant to bring Qt into our default system closure, and furthermore I'd be inclined to wait until more of the aforementioned problems are addressed. What do you think? Mark
