By default, the Mesa libraries are already installed. After installing
nvidia-current (the nvidia
driver you've installed through the jockey), the default becomes nvidia
sinds it takes precedence
over the mesa ones. To change that, use:

     update-alternatives --config i386-linux-gnu_gl_conf
/usr/lib/i386-linux-gnu/mesa/ld.so.conf
Repeat it for x86_64 if you run a 64-bit OS.

Note that Optimus is not supported for Linux, so you really have to use a
solution like
Bumblebee or change your BIOS settings.

Lekensteyn
