StartX command

[Dane Helm]

I have a CL-GD5428 and am trying to get it to work at 24bpp instead of 8.
SO I used Xconfigurater (RH 5.1) and didn't install any "display"(?) at
8bpp.
        But now when I type startx it says:
Fatal server error:
No "Display" subsection for default depth 8

SO how do I change the defualt?

PS: I have tried man X, man X11, and manX11r6 and nothing came baack..
