Sorry, i am not sure what graphic card, i am using. But, all i could say is
that, it was working absolutely fine and all-of-a-sudden displaying a blank
screen.

If this was the problem right from when i installed the software, that is
understandable. Not sure, why it worked before and not after.

By googling, i found out that it could be a problem with configuration of
some files in /etc/X11/ location ??

Below are the messages from /var/log/Xorg.0.log file, does these mean
anything ?
