For some time now, I have been tring to figure out how to get more than
256 colors in X-Windows with little success. I read in the archives about
using the -bpp 16 switch with startx, however my card will not support
that.
xdpyinfo results are included in the message, sorry about the length!
Basically, what I was woundering, if there is a way to tell it to use a
different colormap as the default. The graphics card has modes which
support more than 256 colors, but I just cannot seem to get to those
modes.
Thank you for any info, here is the xdpyinfo output.
