X and Fluxbox :: Uninstalling Xfree86 and fixing Xvesa

I've installed XFree86 through apt-get, but I can't get it to work properly with my video card, so I want xvesa back. I've fixed the symbolic link in /etc/X11/, but startx still doesn't work. I've also regenerated my .xserverrc with xsetup.sh. What else can I do?
Thank you.
