--radiolist "This wizard will install the 3D ATI Radeon (fglrx) Driver. 
This driver will let you play 3D accelerated games, and increase the performance of certain graphic intensive applications, taking full advantage of the resources of your ATI Radeon video card.\n 
Before installing this Driver make sure that your card is a 'Radeon' card, and that the model of the card is in the 9xxx series, 9500 or higher, or it is in the X series (e.g. X300), or it has TV-Out capability. The 'fglrx' driver does not support cards earlier than the 9500.\n\n
This wizard requires that you are connected to the internet.\n\n
Your video card was detected by Klikit-Linux as:\n
$mycard \n\n
If by any chance this wizard does not work, it creates a backup of your previous xorg.conf file (/etc/X11/xorg.conf.klikit), which can be restored with the command: sudo restore-xorg\n\n
Another option to install the ATI driver is using the Envy installer \n
If you use Envy to install the driver use that same program to remove it." 55 80 0 \
