That seems to fix it. Seems like it's missing write access for "other"
(that's the only thing that's missing before chmod'ing as per the
above). Doesn't matter whether it's in /tmp or /home/ubuntu though.

Yep! That works. Actually just using dbus-lunch to run weston makes
gnome-terminal open up without adding --disable-factory. I did see
some messages in the VT after closing weston about dbus not being able
to connect to something. Now gedit runs as well.

Right. Now that I got gnome-terminal running it looks like a DBus
error with rhythmbox (this is when running weston as root):

(rhythmbox:13428): Rhythmbox-WARNING **: Unable to grab media player
keys: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such
interface `org.gnome.SettingsDaemon.MediaKeys' on object at path

and when running as regular user:

(rhythmbox:13668): Rhythmbox-WARNING **: Unable to grab media player keys:
Error calling StartServiceByName for org.gnome.SettingsDaemon:
GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process
/usr/lib/gnome-settings-daemon/gnome-settings-daemon exited with
status 1

and then it exits with a seg fault related to Xkb:

Regarding the Super+Alt combinations (window rotate, zoom, resize) is
that not in weston 0.85 either? Cause it's not working.
