I've already install bumblebee and primus for my lenovo G580 with nvidia 635m.

glxspheres64

runs properly;

optirun glxspheres64

shows only black screen and I received this error in terminal:

joe@G580:~$ optirun glxspheres64 Polygons in scene: 62464 Xlib: extension "GLX" missing on display ":8". ERROR (603): Could not obtain RGB visual with requested properties

Any suggestions? I've tried to reinstall driver couple times with different guides but it is still the same...
