Hi, i have installed LinuxCoin and every time i try to use aticonfig i have this:

user@linuxcoin:~$ aticonfig --adapter=all --odgc
aticonfig: This program must be run as root when no X server is active

user@linuxcoin:~$ sudo aticonfig --adapter=all --odgc
PuTTY X11 proxy: wrong authorisation protocol attemptedPuTTY X11 proxy: wrong authorisation protocol attemptedPuTTY X11 proxy: wrong authorisation protocol attemptedPuTTY X11 proxy: wrong authorisation protocol attemptedERROR - X needs to be running to perform ATI Overdrive(TM) commands
