I followed this guide: http://wiki.debian.org/Bumblebee
. I read that glxspheres is a good test to see if your graphics are working. optirun glxspheres gives me this:
Polygons in scene: 62464
Xlib: extension "GLX" missing on display ":8".
ERROR (596): Could not obtain RGB visual with requested properties
edit- I don't get any error when running it without optirun.
edit2- Is this the right forum for this?
edit3 (lol) - I reinstalled Debian, tried installing again, and now it's working fine. I hate computers...
