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.
