Hello. When I start an X server with the slackware or knoppix 3.4 distro's, the system freezes (because of video). I'll focus on knoppix because that is what I currently use and the problem for both distro's are the same.

If I start knoppix without any boot params ("cheat codes") it will freeze, I forgot at what point it freezes but i beleive it is in the begining of the linux boot process before it even recognizes the hard drives. But if I use framebuffer mode [fb1024x768] it starts normally and starts up KDE.

The only problem that I have with this is that the screen is grainy, lacking a higher amount of colors displayed on screen. I see that in frame buffer mode it uses less colors and I later read up on fb finding out that this method provides no graphics acceleration etc.

How can I get my graphics card to work better with knoppix? Or how can I get Frame Buffer mode to have more color? I had Fedora Core 1 on the computer that has this problem and also Red Hat 8-9 and the X server worked at optimal performance and was very pleasing to the eye.

I reffered to the knoppix faq (KNOPPIX-FAQ-EN.txt) for a solution which is how i was able to start knoppix with
fb1024x768. The section of that file is "Q: My graphics card doesn't work!".

I used
lspci ; lspci -n like the faq said, to get the pci information, the main purpose was to email it to info@knopper.net but klaus knopper already has over 4500 unread emails.

As you can see from line 6 of the lspci output I have an SiS 300/305 graphics chipset and the card itself is a "Pine XP-PCI2800" 3D Phantom PCI. This card has 32MB RAM, and does not support OpenGL too well.. very unfortunate.

So basically I need help with getting this card to work without the Frame Buffer or at least to get the Frame Buffer to run with a better quality display.

Thanks in advance.
