I am trying to select the proper driver for my system. ATI has 'check.sh' which will point you in the proper direction. Logged in as root, I have downloaded it, when I try to run it from within a terminal session, I get the following:

ATI Technologies

You are either not running this script from the console
or simply do not have console ownership. Requirement failed.
Unable to determine XFree86 Version. Stopping now.

thanks in advance

Are you using XFree86 or Xorg? It might be that it won't work with Xorg, but I'm not sure.

And now that I read it twice...

Maybe it wants it to be run from console, not from terminal. In this case, press (for example) CTRL+ALT+F2, log in, and re-run the script. I'm not sure why terminal wouldn't work, but try out. And if it still complains, try shutting X down for a while:
should stop X on most systems (try CTRL+ALT+F7 or F6 to see if it's still going or not), then re-try. And to get back:

thanks for the input. I tried:
1) CTRL+ALT+F2 &
2) init 3

Both had the same results as my first attempt.
