On my white MacBook (2007 eta) that I recently upgraded from Leopard
to Snow Leopard. I have installed all current updates.
Now, and not before, I notice that frequently when I start to re-use
the machine that it has zero brightness when it powers up. The
'increase brightness' control has no effect (but other keys do work).
If I close the lid but then reopen it before the machine goes to sleep
that usually does the trick and I have medium(ish) brightness and can
turn brightness up or down.
I am testing if this is related to X11/Xquartz so thought I would ask
here if anybody else has experience this problem.
I can provide more h/w details later.
Thanks, M
