I have a 32Meg VRAM (12") ibook and have been having trouble with the video out port on it. I'm running 10.2.2
I'm pretty sure it's a hardware problem but wanted to verify that it's not a known issue first.
Basically both the VGA adaptor and the video adaptor both work intermitently...
(Recycling a rumor here)
Let's not forget the remote display capabilities of OS X. Apple can make their own x86 thin-clients to sell,
under $1,000 each to the education market.... a nice beefy OS X server cluster, gigabit network... thin
clients running OS X86 but nobody has to know...
