Setting up color depth manually in SUSE linux 11 SP2 enterprise

Dear All,
I am new to Linux. We have purchased one software in our compony. But whenever I try to install, it is giving error that
error:-Insufficient color depth to display installation panel.

Can anybody let me know how can I set the color depth in SUSE linux manually?
sometimes it is also giving error Xlib: Connection to “0:0” refused by server
Xlib: No protocol specified.
(I am not logging in remotely or X System)

I request help from all of you.
