I have get an Asus N56V laptop with an Geforce 740m Graphics card and Ubuntu version 13.04. Bumblebee refuses to run - when calling optirun "something" it give the error
[ 150.373572] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please [ 150.373667] [ERROR]Aborting because fallback start is disabled.
... and after some time, the system gets hot. So I have to deinstall bumblebee again.
Can anyone please help me with the problem?
