Hi,

I had finally time to get a Sid partition up and running on my optimus
laptop (GT550M). Contrary to what I was expecting, the default
configuration of rootless Xorg works just fine with bumblebee. But I
had problems once I installed xserver-xorg-legacy.

So, could you please try to apt-get remove --purge xserver-xorg-legacy
and restart your X session (logout of Gnome or reboot) and try again?

Kind regards,
Luca Boccassi
