It could be a myriad different things - gotta love GUI install/config utilites. A FEW things that could have gone wrong -
- It didn't put the X libraries in /etc/ld.so.conf
- It didn't configure X to accept connections from
- I didn't even create the XF86Config file
The list goes on and on
Glad you fot it working though. What do you think of Red Hat 6.2? (Follow up's should probably go in the disto forum).
