I have a Dell XPS 17 L702X with an Nvidia optimus card. I have installed bumblebee. Is the following correct?

  • If I don't manually launch a program with optirun or primusrun, then bumblebee is not operational.
  • If bumblebee is not operational, then any installed Nvidia drivers are not being used.

Background: I am trying to work out some problems with Kubuntu 14.04 and OpenGL. I'm trying to work out if it's worth testing different Nvidia drivers.

true. nvidia is put to sleep when you are not using with optimus run. what is the problem –  aveemashfaq Apr 4 at 12:39
    
Thanks. I can't turn on OpenGL rendering. It keeps changing back to XRender. If you answer it with a reference, then I'll accept. Cheers. –  Sparhawk Apr 4 at 13:42

No, my question is as stated in the question above. If I post the problem itself (which is incidentally now fixed), then it'd get closed as a bug. –  Sparhawk Apr 5 at 13:15
