This is a relatively common occurrence when installing to a USB drive, it is caused by xorg.conf being corrupted, or changed. So restoring the failsafe should solve your problem.

First, make a backup of it to be safe:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.bckup

Then, restore the failsafe:

sudo cp /etc/X11/xorg.conf.failsafe /etc/X11/xorg.conf

there is no xorg.conf file inside x11 folder. I cd'ed it and tried to see whats inside of this folder by entering dir command: no xorg.conf folder – Tural Aliyev Oct 23 '12 at 19:43
    
    
Downvoting is for when an answer is wrong, not when it doesn't work for you. The fact I cited my source should further prove it as useful. – Paul Oct 23 '12 at 20:09
    
So using your first screen, check your /usr/lib/X11/ folder for xorg.conf and modify the commands above, if you do find it there. – Paul Oct 23 '12 at 20:13
