*WARNING* Failed to find either 24-bit TrueColor or 8-pbit PseudoColor Visual.

plz help me
 

I think this is a problem with the VGA card. You need to increase the scren resolution into 24 bit. This can be done by GUI ( system tools --> display ) [ i am not quite sure of this but u can find display related menus in the redhat's start menu ]

I have ever installed Mandrake on several PCs. Sometimes it is configured with 24-bit color automatically. Sometimes it is configured with 16-bit color and can't be changed to 24-bit by GUI. But modifying /etch/X11/XFree86config-4 can sometimes solve the problem.
Just for you reference.
