Pixelated / low res on Compaq Armada 1598DMT
I've got a pretty old Compaq Aramda 1598DMT, and Knoppix works perfectly except:
When in xfree, everything is extremely pixelated (fonts/icons/background/etc). It must be an X problem as all the fancy problems prior to xfree look fine. Anyone know anything about this kind of issue?

It would appear that the resolution that X/KDE is starting up in is not the native resolution for your machine. One of the drawbacks to an LC display is that it has a fixed resolution; anything displayed in any other resolution will look blocky or pixelated because the image is not mapped to the display. An example would be a 800 x 600 pixel desktop displayed on a 1024 x 768 LCD; some of the desktop pixels would map to multiple pixels on the physical display, causing text (for example) to look very strange.
You may want to try some of the cheat-codes. They are documented here -- I don't have a laptop to test them -- maybe someone else can leap in. Look at your documentation to find the native resolution of your LCD.

That would help to explain the craziness I was experiencing. I think it's fixed now but certain images were seriously blocky / pixelated while X was starting with a depth of 16 (what Knoppix detected :?). I changed it to 24 and the problems I was having seemed to have disappeared.
I wonder tho... would it be possible to determine the fixed resolution via software or if the size / type of the LCD was known? I have a 14.1 inch TFT and of course the documents don't say a thing about it :roll:
