I even discovered that GDM looks different when acceleration is available ;)). So these are two separate problems: - Acceleration detection on some systems, from my limited tests, it works on nVidia (32bit, will check 64 shortly), and fails on intel (mesa???) graphics. This can be a bug report for gnome-session (/usr/lib64/gnome-session-check-accelerated*) or for Mesa if it's it what breaks things. - In full mode, gnome-shell from the user replaces gnome-shell from gdm. But in fallback mode, gnome-shell can't replace GDM's metacity. > > TIA > > >
