journal from Live DVD boot with gdm debug enabled

Testing a Live GNOME DVD with the proprietary nvidia340 driver. As expected, the initial gdm-wayland-session fails and gdm falls back to using a gdm-x-session. But it then goes to the login screen, instead of reattempting the autologin.

    live.cfg: for GNOME, disable Wayland when we know it won't work.
    
    This works around the gdm autologin bug (mga#20079).

Comment 3 Martin Whitaker 2019-04-13 22:09:25 CEST 
Latest GDM appears to automatically detect that Wayland won't work when the nvidia340 driver is used, so I can no longer test the fallback behaviour.

Leaving the workaround in place.
