Install of Knoppix 5.1 ends in a black screen. The integrity of the install disc is ok (md5 ok testcd ok.) I contacted the manufacturer of my computer who informed that there is a problem under Linux with the video card, a Volari GX-6200XL Ultra. I checked the XGI website and found that there are Linux drivers for Volari cards, namely: V3-Linux-V1.0-0815.tgz.

Point is I don´t know how to use the driver during installation (if that is the problem).
