does not exist in /etc/ati. This suggests that the ATI driver
is not installed, the ATI driver is only partially installed,
or the current ATI driver is an older version than the
one this script was designed for. Both files listed above are
required for determining where installed files are located.
To force uninstallation of the driver by guessing where the
uninstallation files are located, set the FORCE_ATI_UNINSTALL
environment variable and re-run /usr/share/ati/fglrx-uninstall.sh (this is not recommended).
