Comment 7 for bug 1043518

I've gone ahead & tried the nomodeset option multiple times. (7)

Twice it worked fine to produce a workable live session/installer
Twice only got a black screen, once with splash screen, red lights, never proceeded
Once got usable live session though also removed splash quiet from boot option
Once got the live session but unity wasn't loaded
Once got live session with constant windows flashing

This machine has never before had issue like this - started after the removal of unity-2d & the inclusion of the ...904/5 xserver on live iso
