Moved your topic here and updated the subject to include your problem. The NVIDIA GeForce FX Go5700 seems to not be well supported on Linux. Perhaps somebody here can offer additional suggestion.
I did find this topic on the Ubuntu forums with users have the same issues as you (comment #17): http://ubuntuforums.org/showthread.php?t=1976161&page=2
. I'm not sure as to the solution for it.
Can you add which desktop environment you picked (Cinnamon / MATE / Xfce / KDE) and whether you installed 32-bit or 64-bit?
