CodeWarrior X problem

I have had CodeWarrior running on one machine for months; no problems.

I got another, faster, machine and want to move CW from one machine to
the other. However, I get the following message when I try to run it on
the new machine:

# /usr/local/bin/cwide &
Warning: Unable to use any of the requested depths, using default depth
instead
Fatal Error: Server cannot support required visual.
#

Both machines are running RH6.1.
The video cards are different; different drivers.

Ideas?

Thanks, Ed.
