[PD] Gem B3 on g4 733 with Nvidia card

[bbogart]

Hello Mac guys,

I had a little more time today to try and get gem beta 3 to work on my 
machine, without any luck. I have recently upgraded to 10.2.

I have the stock nvidia card that came with the 733 (geforce2 I think) 
and I added an ATI xclaim VR (for video output)

PD now loads the gem lib fine:

GEM: IOhannes m zmoelnig
GEM: ver: 0.87+cvs
GEM: compiled: Nov 27 2002
GEM: Mac OS X port by James Tittle & Chris Clepper

But when I try and create a gem window I get:

Could not find valid pixel format
AGL Full Screen: 640 x 480
MAC:  no info.context
error: GEM: Unable to create window
error: GEM: gemwin: no window made

According to the OpenGL info developer util (which can't copy paste) 
sees both cards:
Render 0 (nvidia) has:
	HW acceleration
	fullscreen
	mpsafe
	window
	compliant
	screen mask

Render 1 (ATI)  has:
	off screen
	robust
	backing store
	MPsafe
	window
	multiscreen
	compliant
	screenmask
and no HW acceleration.

Does this give any indication as to the problem, seems to do the same 
thing if I put the PD window on the second screen and try creating a 
gem window.

Hope to get it fixed I really wanna try the firewire video input 
stuff!!!

Thanks
ben
