Ubuntu 12.10 OpenCL OpenGL Interop with ATI graphics

view story

http://askubuntu.com – I have successfully installed the ATI Catalyst drivers on a my ATI hybrid graphics system running on Ubuntu 12.10. I have verified that OpenCL and OpenGL work independently; however OpenCL-OpenGL interop is not functioning correctly. I've done some debugging, but am not sure where to go from here. Can anyone help? Details: My system is an HP Envy 6 running Ubuntu 12.10 (all updates applied) with a ATI hybrid graphics system composed of an Radeon 7600m and Intel HD3000. I installed the latest ATI Beta drivers (v. 12.11) following these instructions: Ubuntu 12.10 AMD/Intel Hybrid Graphics (HowTos)
