Hello Alexandre,

I'll answer your question, so that not always the same people on the
list have to do this :)

The answer to your question is: yes, there are happy people who can use
both cards with 3D acceleration. For Ubuntu and Debian, there is the
marvelous janitor script by Raphael Gradenwitz, which solves all
problems (see http://global-social.net/sony-VGN-Zseries ).

The problem you run into, is that you have to keep the GL libraries for
both cards on your system and put the right ones (depending on the
active card) in place when you boot. This can be done by a script
in /etc/rc*.d. Moreover, you may like to have a separate xorg.conf for
each card, which also has to be put in the right place, before the start
of the X server.

I wrote a step by step guide to set this up on Ubuntu. This will work
for Fedora, too, you just have to twiddle some paths. Find it at
http://www.welfenlab.de/fileadmin/download/Installation-sony-vaio.pdf

Much better would be to adapt Raphael's script to Fedora, but you have
to have a good grasp of shell programming to do that.

Hope that helps.
