When I'm not locally logged into my Linux machine, my GPU wasn't appearing in the list of devices.  I tried running with DISPLAY=:0, and that fixed it.  However, what happens if I'm running a GUI program that's OpenCL accelerated?  Changing my DISPLAY environment variable would send the UI to the wrong place!

Is there some alternative variable I can set for the APP SDK, that will override DISPLAY?

Excellent!  Thank you!

Is this documented anywhere?

This is documented in the SDK release notes:

Thanks!  I actually started to read those, but was too excited to try out some of the samples.
