I have a fixed-frequency greyscale monitor which I was finally able to get to work after downloading the modelines from si87.com (very nice people) I have a stable X display and all. However, I am having a few problems.
As this is a greyscale monitor (green signal) it only displays 256 out of 256 'colours', so using 16 or 24 bpp is pointless. However, the apps running seem to think they have an 8-bit palette out of 24-bits of possible colour, and I get netscape and xv switching contexts as they're wont to do at 8-bit colordepth. What I would like to know is how to make them stop. I think what would have to happen is to force all apps to use a single greyscale palette. I just haven't been able to find anything in the documentation for the X servers and the XF86Config manpage except for setting the 'visual' to 'grayscale' in XF86Config, which seems to have no effect at all. So what do I do?
