VGA out on ibook2

Hi
I'm trying to use the external VGA connector on an ibook2 (the white
one) with the benh utility m3mirror and, after turning crt on, the screen on the monitor looks "wavy" and unusable.
Anybody could guide me to solve this problem?

Same problem here. If I include the crt:1 option in the kernel booting options, the waves dissapear and the console looks good, but the X colors are all wrong. Looks like the crt is in 8bpp while X and the lcd are in 16bpp. Tried this with 2.4.10-ben0.
