No, this is it (the thread continued into this month):


I think we can probably get the other one working by fiddling some more with
the registers. I tried the most obvious things but to no avail yet.

I have picture before X is up.

There's a workaround for the slow X startup; add

 Option   "NoDDC2"

to your X config, as documented here:


I have not had time yet to investigate the real cause of this problem.

It's an nvidia-based card, and I use the free (nv) driver, not the
proprietary nvidia driver. Hence, no acceleration, and hence I have not
experienced those problems. We should fix this though. What version of the
board do you have? 

Suggestions on getting the interrupts sorted out?
