The reason the 8bit PseudoColor visual is there is that many old X
programs only know how to work with PseudoColor; give them a TrueColor
visual and they either refuse to run or display screwed up colors.

I think that the reason for this is that so many Sun machines shipped
(10 years ago) with 8bit only framebuffers.  Thus it became what
programmers used when writing apps for X.

If you want to, you can (should be able to) pass in a -visual on the
command line and it will then use that visual.  You use xdpyinfo to
look up the visual e.g. 0x29 then pass that in.  Of course since GNOME
starts 12 different programs it might take you a while to figure it
out :-)
