I am trying to run the live cd of BT3 on a vaio sz series laptop with hybrid graphics X3100/8400M.

When I use the Intel X3100 chip I get into KDE just fine only the screen is small. How do I fix that screen size. Basically the screen is 1024x768 and part of teh screen is black and not used by KDE. However, when I use the NV 8400M chip I get the "no sscreens" error. I get the error even after I run xconf.

What do I need to do to get BT3 beta working from the live cd? It is a work laptop so I can't install it to HDD. Is there someone in the community that can provide me with the steps to get it running with the 8400M and compiz?
