Bumblebee: Cannot access secondary GPU - error: [XORG] (EE) No devices detected
After upgrading to 13.04, I get this error and other answers (Optirun glxgears: Cannot access secondary GPU - error: [XORG] (EE) No devices detected, 'Cannot access secondary GPU' error with Bumblebee) didn't help.
dpkg -l | grep nvidia

Ask for further details, if needed!
Solution 1:
The following AskUbuntu answer fixed it for me: https://askubuntu.com/a/285638/47280
Basically, you need to edit /etc/bumblebee/xorg.conf.nvidia and uncomment the following line:
BusID "PCI:01:00:0"
In the config, it states that this is necessary for Ubuntu 13.04. This number refers to the BusID of your GPU, so if it's different then go to the other answer for full instructions.
Solution 2:
I found the following file:
/usr/share/X11/xorg.conf.d/10-nvidia-current-latitude-e6530.conf
I deleted it and optirun worked!
Solution 3:
In /etc/bumblebee/xorg.conf.nvidia , uncomment
BusID "PCI:01:00:0"
and replace with
BusID "PCI:0x:00.0"
where x is the number that you see in 'lspci' list next to 3D controller, which should be your nvidia card
