[Bug 989793] Re: blank screen on startup

Hi Steve, I am not sure about EFI. My PC is not at all new (Dell E521) 
and it seems to have a standard BIOS to me. The only slightly unusual 
thing is that I boot it from an external USB hard drive, as this is all 
just experimental. My SATA drive still has 10.04 on it. Is it possible 
that the system "thinks" I have EFI when I dont, and that is messing 
things up?

Title:
  [nouveaufb, efifb] blank screen on startup, "Visual is
  FB_VISUAL_TRUECOLOR; not using graphics"

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  This boot screen with "Ubuntu" and the dots works fine on the live CD. But after installation it is either a blank  black screen (mostly) or occasionally a purple screen with "ubuntu" in a tiny terminal type character font.
  On shutdown it usually shows purple screen with a tiny white ubuntu and some console type message across the screen.
  Logout briefly shows a black screen with tiny ubuntu text.

  This is on a Dell E521 with an nVidia Geforce 7300 LE card using the nouveau driver. 32 bit PAE kernel.
