Thanks for posting this, I had the same problem of a blank screen as it was detecting hardware with a system I recently built. My graphics card is a little different but similar as far as the TI goes, my card is an MSI 560GTX Ti 448 Twin Frozr III with an ASRock Fatal1ty Z77 Professional motherboard. The xmodule=fbdev cheat code worked like a charm, but yea this is also the first time I've encountered Knoppix not working right out of the gate. I am also using the v6.71 DVD version (booted off a USB flash drive). I tried xmodule=nv prior to searching here and had the same results where it just sits there saying the graphics card may not be auto configurable and if no codes are given it spews out the stack dump then goes blank and sits there. Just posting to voice my added concern about this and hoping it can improve Knoppix a bit, it's great
