No GLX output with 285.05.09 drivers on Quadro FX 350M
Installed the latest binary release with no problems. nvidia-settings returns the correct driver version.
Running glxgears produces no video output (just the black background). The FPS seem acceptable, however.
Glxgears is calling the correct libraries.
This problem also breaks any 3D functions in window managers (unity, for example).
Note that if I downgrade to 173.14.30, 3D acceleration does work (glxgears shows gears).
Also while working through this issue, a 1 pixel wide vertical line has appeared on my Dell Precision M65 display. After some googling, this appears to be the result of a manufacturing defect of some over-heating NVidia chipsets.
