Right. But I have to admit that I believe I'm better at coding than at
documenting, which is a poor excuse for beiny a lazy writer.

Luckily, there seem to be people who voluntarily write books about
Knoppix and other Live CDs, so, I don't really have to do this all by
myself. ;-)

Right, that's why Knoppix tries to figure out the optimal screensize on its own, using the DDC information from the monitor in combination with the card information. This works fine for several monitors that provide correct DDC information, but if they don't, the "sane" default of 1024x768 is taken.

You can check with ddcprobe and ddcxinfo-knoppix.

That should be working, if the hardware would just provide correct
information to the OS.

Btw, I have seen monitors claiming they can only do 1x1 pixel resolution
at 1 Million Hertz refresh rate, or 1x1 Million pixel at 0 Hertz. You
got to have a sane default to handle this, und just ignore nonsense
values. mkxf86config and ddcxinfo-knoppix tries to do this.

I would be extremely grateful if you could send a patch with your
changes after you fixed these bugs. :-)

Btw, the new list address is debian-knoppix@lists.debian.org. I
forwarded this mail there, hope you don't mind.
