Hi James,

I created one user in CLI console mode and try to login to KDE but still failed.

Meanwhile, I'll try all the solutions that others sent to this list..

If it fails for all users, then any fixes that involve files in a home directory won't work. What happens when you boot into a shell prompt, instead of the desktop and issue the command startx? Try for the other user as well and for root.
