Ok, here's an update on my gem troubles...
I've repartitioned my hard drive and installed Ubuntu 8.04 and Pd
version 0.42.5-extended-20100114. I've also installed the ATI driver
which is now available in Hardware Drivers. So far so good.
I can open the gem patch I sent yesterday, but when I click [create,
1( I get the following errors in the console:

error: GEM-Xwin: BadAlloc (insufficient resources for operation)

error: GEM-Xwin: GLXBadContext

error: GEM: problems making glX-context current: refusing to continue
error: GEM: try setting the environment variable GEM_SINGLE_CONTEXT=1
error: GEM-Xwin: GLXBadContext

error: GEM: Unable to create window
error: [gemwin]: no window made
... you might be able to track this down from the Find menu.
error: GEM: Create window first!

I tried running pd from gdb as IOhannes suggested and it outputs the following:

Starting program: /usr/bin/pd

The program is running.  Exit anyway? (y or n) y

So it seems that my gem issues are not driver related? Can anyone shed
some light on what is going on?

thanks
