Comment 94 for bug 969489

Ubuntu 13.04
Intel SSD
i7 4770S
Using the processor graphics with the default driver.

I got the black screen with a white mouse cursor about a quarter the time on boot and finally discovered the machine wasn't broken/crappy by pressing CTRL-ALT-F1 to see if tty1 would work (previously I would just press reset when the black screen issue came up).

I tried the sleep workaround here and have had good results so far (I used a 1 second delay):

Is there some way to detect the error state and present an error message to the user instead of the black screen? A fix would be better but it would be nice if we could at least give a little feedback so users don't assume Ubuntu is broken.
