I have officially lost my linux virginity and bought a copy of knoppix 3.3 on cd. The only problem is the display is heavily distorted and no amount of fiddling on my part seems to produce any results. On start up the screen is fine but once knoppix has loaded the image bends in and overlaps itself on either side of the screen. At start up it gives a list of possible commands so i enter Knoppix screen 1024x768. which is the original setting from win2k, and away it goes i tried several diff ones but this seems to ahve no effect at all...

Any suggestions?

Refer to ftp://ftp.uni-kl.de/pub/linux/knoppix/knoppix-cheatcodes.txt

--Try boot: ' knoppix xvrefresh=60 ' or whatever is on the back of your monitor. If you have a decent monitor with controls in the front, you may need to adjust the picture using those. If these don't work, post monitor make/model here.

Try knoppix screen=640x480 for a start.
That's what I'm stuck at so far.
When Xwindows starts in KDE, I have 3 overlapping images of the screen tiled horizontally across the screen, if I try 1024x768.

My monitor is an HP D2804A Super VGA, and I have no idea what to use for H and V refresh rates, they're not on the back.
I can get 1024x768 24 bit color in Windows 98SE and the Mandrake Live CD, but neither of those tell refresh rates either.

Try knoppix xvrefresh=60 screen=1024x768 and you may want to put the xmodule=?? cheat code (http://www.knoppix.net/docs/index.php/CheatCodes) for your video card on the line as well.

60 is not the correct value; just like 5thelephant, I have tried several with no joy.
I don't actually have a video card.
Or a sound card either, I have that insane shared memory all-in-one processing on the motherboard, which I suspect is part of the problem.
I do know it uses the Sis 630 chip, but I've no idea which module to tell it to use.

--Try a framebuffer mode.

boot: ' fb1024x768 '

--Aside from that, you can try passing ' xmodule=svga '.

Thanks, I'll give that a whirl, and let you know how it turns out.

If that doesn't work, try:

knoppix noddc

at the boot prompt. I had similar problems & this worked for me.

Cheers,
Ian.
