I know the old "quake" game did that.
I think that you should divorce these two different problems. First, make the server emulate PseudoColor in software, and simply provide PseudoColor visuals. Second, stick a hack into libX11 (or make a new hacked libX11) that allows users to run apps which assume the default visual is PseudoColor, by mucking with the list of visuals returned from the server. The behavior should be controlled by an environment variable. -andy _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
