Answer 1

Try backing up and removing /etc/X11/xorg.conf:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

Then restart X.

Answer 2

If the problem is with xorg.conf, then please follow this steps as:

Xorg -configure

mv ~/xorg.conf.new ~/xorg.conf

Xinit or init 5

And If the problem is with the Xserver itself, then you need to parse the log file to find out the cause.
