Unabled to start X after running yum installgroup "Java Development"

[Ali, Saqib]

This morning I installed Java Development tool using the following cmd line:
> yum installgroup "Java Development"

And now I am unable to start X

The xorg.conf and Xorg.0.log are located at:

Any help in debugging this issue would highly appreciated.

Thanks
