15 The "black" is the monitor being driven beyond it's spec in either
16 vertical or horitizontal or both.
18 For it to work, you'll need a proper mode line that can be stolen from
19 some other Linux system via a google search or by downloading puppy
20 linux and using that to work out what X is doing.
22 With X and gfx, /var/log/Xorg.0.log is your friend. Especially when
23 used with a google search on the error message.
