I recently had to reinstall my Ubuntu 14.04.3 and now have problems with using bumblebee. I installed it as per https://wiki.ubuntu.com/Bumblebee, but when I try to check it I get this:
ilya@ilya-GE40-2OL:~$ primusrun glxgears primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please
ilya@ilya-GE40-2OL:~$ optirun glxgears [ 121.851700] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please [ 121.851723] [ERROR]Aborting because fallback start is disabled.
PS My laptop is MSI GE40 2OL with nvidia card G750M
