--- Comment #38 from Alexandre Demers alexandre.f.demers@gmail.com 2012-03-05 20:40:48 UTC --- Some news: today, I updated xserver and it seems I'm now able to boot under Gnome-Shell correctly.
However, launching RenderFeatTest.bin64 still hangs exactly where it has been hanging for some time now and freeze my window manager. At least, it seems one of the problem was related to xserver.
I'll hope I'll be able to find something new in the logs.
