I've rediscovered this bug, or something very similar.
My system is a Mac Mini Solo with 2GB memory, running Ubuntu 8.10 + recent
updates.
During the run-up to Intrepid release I had no trouble like this. Now, after a
few updates, it's back.
The first black screen was while running virtualbox
Following the suggestion from Smurphy I've added the 'Option
ForceEnablePipeA' line in the xorg.conf .
This evening the screen had the alert window below:

The following error was encountered.
You may need to update your configuration to solve this.

I count at least four people commenting on this bug who are still
affected on Intrepid, so I think it's safe to say it hasn't really been

it's fixed, so I'm reopening it.
