I'm running Ubuntu 13.04 64-bit on a machine with an NVIDIA Quadro FX1500 graphics card. I installed gazebo following the instructions in the tutorial. The gzserver starts fine. If I start gzclient using the proprietary nvidia-304 driver it crashes with the following output:

The guys at this and this link seem to have had a similar problem, but as I'm running 64-bit Ubuntu with the latest driver these solutions don't work for me. When using the open-source driver gzclient starts but the computer is unusably slow.

Any idea on how to fix this?

EDIT: glxinfo runs without an error as far as I can tell and tells me Hardware Rendering is enabled:

direct rendering: Yes
