Well, I just got around to updating my Mini to Lion. And
guess what? Had the infamous no signal. Played around
with pulling power, zapping PRAM, unplug and plug routine
with out results. For grins and giggles, I took a Display Port
to HDMI adapter and tried the connection that way.
Guess what? With the display port adapter to HDMI I got video!
Got through the initial boot stuff and to my dektop and things are
functional.
Here's were things get weird. I shut down, plugged the HDMI cable
back in directly, rebooted and it worked. Then shut down again.
Waited for several minutes and rebooted. Black screen!!!!
Forced shut down. Plugged it back together with Display
adapter. Restarted got spinning cursor gray screen then
black, forever. Forced a power down. Started up zapping PRAM,
reboot after zapping PRAM brought screen back to desktop.
Haven't shut down yet waiting to repair permissions, while I can.
