And since the Linux kids with there TrueColor only displays have taken
over the world there are no X applications that can play nice with less
then TrueColor. ;-) (Remembring a startup of enlightenment on a 8 bit

Looking at xdpyinfo, there are still several 8 bit PseudoColor visuals.
The default visual, of corse, is TrueColor. IIRC the depth of the root
window is 8 bit in the SGI standard config and my changes to the Xserver
startup made the depth of the root window 24 bit. I remember saying
someone that the difference 8 bit root window on a 24 bit display is
what confuses most "modern" software.

Well. Maybe it is a GDK/GTK problem, not only GNOME. But as it can be
cured by Xserver startup parameters I went this way.
