How to Fix BackTrack 4 “No Screens Found” Error
The other day I was reading an article about BackTrack 4 and it got me very interested to the point that I decided to test it out. I created a Live USB and ran the OS in one of my older laptops, everything worked fine and I messed around with some things. I liked it so much that decided to do Dual Boot with my newer laptop which has an ATI graphics card and AMD processor. I decided to try first with the Live USB just to make sure everything was going to work and right after I typed "startx" I got the following error:
Fatal Server Error
No screens Found
I did some research online and with the help of Google and found a solution, seems like every time I use Google I find a solution 
.
To solve this, type "fixvesa" and you will get a message. After the message type "startx" again and it should work. This only happened with my newer laptop which has an ATI graphics card and AMD processor. I will soon write some posts about BackTrack, if you would like to learn more about it, you can visit their sitte, BackTrack-Linux
