Display nolonger works correctly

[RaenirSalazar]

I was using 8.04 and then used EnvyNG to enable dual monitors, then I upgraded to 8.10 and my display nolonger worked correctly. Essentially for some reason my display was pushed from my main monitor to my second one and my main only displayed the "void" that remained so it remains black, while my second screen for some reason only displays roughly 1/4 of the desktop the top left to be exact.

Removing EnvyNG hasn't changed the problem. I had to boot in low graphics mode to try to get any kind of temporary fix, currently upgrading again to 9.04 to see if it changes anything.

seems to have been solved but still some issues, partly with the 2 screens simply the "same" output and not an extension of my desktop and seems to be some odd slowness when navigating Ubuntu.

Okay my Display Preferences window in 9.04 is bugged, it just displays a blank window with a teal coloured bar and my computer slows down and becomes "jerky" in its movements.
