Hi, id' like to change the default screen size from 1024x768 to 800x600
because i have old monitors which do not work with the default resolution.

Hi pankepasa,

You should read the cheat codes in the docs section to learn more about various the various startup options. This is the short answer:

1. At boot press the F2 key and you will be presented with the KNOPPIX cheat codes.
2. Enter "knoppix screen=800x600" without the " "
3. Voila, you have 800x600 X in all its glory..

You may wish to examine the cheat codes closely as you may wish to invoke other options as well say a wheelmouse which is quite handy. You could invoke both options thusly

"knoppix screen=800x600 wheelmouse"

All the best, Dan

Hi pankepasa

I think I may have misunderstood what you were asking with my previous response. If so I am sorry. I lost track of which forum that I was in. I thought I was responding to a usage as apposed to a customizing question..

All the best, Dan

Yeah, what I was looking for is how to remaster it so that the default
screen is the 800x600 screen. Then you could change it to 1024x768 with
the F2 and entering the properly cheatcode.

Thanks anyway :-)

Hmm, havn't really looked a lot into how X-detection is done, but you could check out /usr/sbin/mkx86config (or something similar). as far as i know this generates the xf86config file.

Another way would be to edit syslinux.cfg in the boot.img, and change the default kernelparameters to always include the 800x600 option.

Hope this helps,
