1916720 - dbus should be launched earlier

Status: RESOLVED FIXED

(Testing :: General, enhancement)

Description

[:gerard-majax]

In https://bugzilla.mozilla.org/show_bug.cgi?id=1892254#c2 I spotted that we lacked GNOME Screencast exposed on the DBus but it turns out we were poking at the wrong session bus. Starting things differently helps.

Attachment: Bug 1916720 - start dbus before X session in linux tests. r?ahal,jmaher

We were previously running dbus twice: once as part of the X session scripts,
with all the gnome things, and a separate one for our tests and a gnome-keyring
daemon that test-linux.sh runs. By launching dbus before the X session
scripts, they can all share the same bus and firefox in tests can talk to the
other services listening on that bus.
