Just all the sudden compiz failed and I couldn't get it to relauch so I rebooted the system. Ever since, after the Ubuntu login screen (with 5 round circles in the middle. It just goes to the next screen which is black with various tasks displaying [OK] at the end and freezes. I've switched over to a terminal session and removed fglrx and reinstalled xorg-default drivers. This didn't help because I had a suspicion it was an issue with X. Not sure where else to go but a reinstall. Any one have any ideas to try or to get further where the boot is failing.

Of note, when I reinstalled to the open source drivers, I got a screen saying hardware not detected properly and I hit ok to continue for one session. Then froze at the same screen again so appeared not to be to open source or proprietary drivers.

Do you see any errors while running startx in the terminal session? If so, could you paste them (or send a photo, if you can't)? –  MiJyn Jul 19 '12 at 2:31
    
@lkjoel - screenshot link added. That is as far as it gets which just shows a blank screen with an arrow. –  J Spen Jul 19 '12 at 2:43
    
So nothing happens after that? No display at all? And what's the ^@? –  MiJyn Jul 19 '12 at 3:53
    
@lkjoel - It forces me over to the x-windows (Ctrl-Alt-F7) but it's just a black screen with an arrow cursor on it that can move around. If I hit Ctrl-Alt-F1 i see what I took a photo of which 2 hours later now still hasn't changed on either screen. If I force close and do it again it hangs at the same spot. The ^@ is just from accidently hitting some keys on the keyboard so ignore that. –  J Spen Jul 19 '12 at 4:11
    
@lkjoel - If I boot into recovery mode. Even with failsafe graphics still a no go. –  J Spen Jul 19 '12 at 4:28

I had reinstalled the system but likely the stated answer of:

sudo service lightdm restart

will do the trick from having a similar error on another computer.
