What the Hell? I got a install script to update the drivers for my video card, and when I go to run the script by typing ./install.sh I get the message that I don't have XFree86 installed. XFree86 is the X Windowing system, correct? I ran it from a shell prompt in GNOME, I also just tried not starting X and doing it from a prompt there, but I get that same error, any Advice??

Thanks

if you ran the script from a prompt in Gnome, then X is installed. It may be that the script you're trying to run is looking for a different version of X.
Is this a package or just one script? If it's a package it may have a 'configure' script to run first. That could fix the problem.
You may want to open the script in an editor to see what version of X it's looking for, or the path it's using to find the files.
