Description Ray Strode [halfline] 2012-03-27 19:01:18 UTC 
Now that software gl is getting good, we should consider doing a Setenv("LIBGL_ALWAYS_SOFTWARE", "y") dbus call to gnome-session when we hit an r200 card or whatever instead of failing.

This way we get gnome-shell et al.

Of course, multi-screen zaphod mode setups would still need fall back mode.

gnome.session: don't have IsRunnableHelper

We now have no fallback mode, so there's no point in running
the IsRunnableHelper.

check-accelerated: only cache result if successful

If it's unsuccessful it may be successful in a subsequent run,
so caching it can cause problems.

main: automatically fallback to software gl

Now that we have working software GL available, use it if
hardware GL isn't up to muster.
