Screen resolution

[Matth]

Hi

I've just downloaded Knoppix and burned the CD and the first boot process just worked fine.

I have a 23" flat LCD from HP that has a resolution of 1920x1200 pixels, but Knoppix only shows me 1024x768. I have tried "knoppix fb=1920x1200" or "knoppix screen=1920x1200" but the max resolution I get is always 1024x768. And all the different options I can chose once it is up are all lower resolutions.

How can I get the higher resolution to work? Any help appreciated as I'm an absolute Linux illiterate.

No help but I have the same issue trying to get to 1280x1024 and stuck at 1024x768. I also tried what you did to no avail. So I add my plea for help to yours.

One of two things have to happen first.

A: knoppix correctly finds and sets up your video card.
B: You manually change the XFree86 config file.

Hi Firebyrd

Does this mean, that I then have to boot from a floppy disc? Is there no way to do it by cheat codes?

As I'm a complete Linux newbie, how would I set up my video card and change the config file?

I do have a Hercules 3D Prophet III card and a HP L2335 flat panel monitor.

Thank you for your help.

Him, not entirly sure on this one.

To really save an configs You would need to have a config file or hd-install.

Pain, yes.

There is however an option in the KNOPPIX menu to install software while running the cd. In it is an option to install nvidia drivers. Try that out.

My XFree86 config file shows all available video modes from 1280x1024 down but only 1024x768 is available. How do I go about changing it to recognize other modes?

try the fb=(screen resolution) along with vsync=(try different values ex 60,70) cheatcode. but becareful, the wrong setting could eventually ruin the monitor. If the vsync # isnt correct the screen will be unreadable.
