Ok, I have installed BackTrack 4 Final Release onto a empty machine using the live environment version on one of my USB thumb drives. It boots up fine and logs in to root without any problems but when the startx command is inputed the splash screen appears and gets to initializing system services and hangs for abit there and then the splash screen vanishes without finishing the normal splash screen cycle, leaving in its wake a blank screen with only a pointer.

I then decided to try and boot up the machine using a persistent version of backtrack which i installed to one of my 8 gigabyte USB thumb drives. This works perfectly. It boots up fine logs in fine and loads the GUI fine.

If anyone has a solution to this problem it would be much appreciated.

all the best,
