NVIDIA 64 bit + Knoppix64 not working

[DTeCH]

Maybe the card is trash too, but whatever. I downloaded Knoppix 8.6.1, & it s nice. The trouble with it is that Synaptic Package Manager doesn't work, & I switched desktops from lxde to Gnome, & was never able to get back into any desktop, Not even lxde... it just hangs at the Knoppix Penguin logo. Ctrl+Alt+F2 gets me back to the command prompt, & init 2 takes me to text mode. Then init 5 tries to load the desktop again, but it just hangs. Never Loads. I pressed Ctrl+Alt+F6, & saw WARNING messages about GTK 3, saying that GTK 3 didn't load, & GTK 2 or 2+ cannot be loaded in the same session, or something like that.

I clicked "(Re-start/Choose) Desktop", or something like that, & it just seemed to go to text mode after I chose Gmone, then it tried to return to Gnome instead of lxde, but it just froze at the Knoppix Penguin logo. Now I can't get back into Knoppix with any Desktop... not lxde, KDE, or Gnome. No idea what to do. Will delete the knoppix-data.img & try again. Maybe it's the graphics card? Lol I'm tired of this stupid card anyway. Maybe it's a bug?
