Hi.

I'm not sure if this relates with the same problem but I think I'm experiencing
the same issue. I've tried posting directly to the mailing list but I got no
response so far -- maybe because my email address is from yahoo.fr and I know
there had been some issues with Yahoo.

I've experienced such an issue on Gentoo Linux with xf86-video-ati-6.9.x and
Xorg server >= 1.4 (IIRC) and on Ubuntu 8.10. When X starts on my laptop *and*
an external monitor is plugged in (either VGA or DVI), both screens start all
black, no image is displayed.

Switching to a console doesn't even work. I have to power off and restart my
laptop. The machine reacts to keyboard input (at least Caps lock and Num lock)
but I can't see anything else on any monitor.

OTOH starting running xrandr *after* plugging an external monitor does produce
the expected results. It means I must plug my external monitor *after* X
starts.

That issue never happened with radeonhd driver. This issue hasn't disappeared
with the latest xf86-video-ati6.10.x.
