I used to run bumblebee successfully on my previous Ubuntu 12.10. But ever since I migrated to elementary os Luna, which is based on Ubuntu 12.04, I have been trying with no luck to get bumblebee Working.

When I run optirun glxspheres64, it says

[11119.768519] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initiate mode change.

[11119.768595] [ERROR]Aborting because fallback start is disabled.

Here's the output of optirun -vvv glxspheres64 ,

[11701.336788] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf

And my /etc/bumblebee/bumblebee.conf is,

# Configuration file for Bumblebee. Values should **not** be put between quotes

## Server options. Any change made in this section will need a server restart
# to take effect.
# The secondary Xorg server DISPLAY number
# Should the unused Xorg server be kept running? Set this to true if waiting
# for X to be ready is too long and don't need power management at all.
# The name of the Bumbleblee server group name (GID name)
# Card power state at exit. Set to false if the card shoud be ON when Bumblebee
# server exits.
# The default behavior of '-f' option on optirun. If set to "true", '-f' will
# be ignored.
# The Driver used by Bumblebee server. If this value is not set (or empty),
# auto-detection is performed. The available drivers are nvidia and nouveau
# (See also the driver-specific sections below)
# Directory with a dummy config file to pass as a -configdir to secondary X

## Client options. Will take effect on the next optirun executed.
# Acceleration/ rendering bridge, possible values are auto, virtualgl and
# primus.
# The method used for VirtualGL to transport frames between X servers.
# Possible values are proxy, jpeg, rgb, xv and yuv.
# List of paths which are searched for the primus when using
# the primus bridge
# Should the program run under optirun even if Bumblebee server or nvidia card
# is not available?

# Driver-specific settings are grouped under [driver-NAME]. The sections are
# parsed if the Driver setting in [bumblebeed] is set to NAME (or if auto-
# detection resolves to NAME).
# PMMethod: method to use for saving power by disabling the nvidia card, valid
# values are: auto - automatically detect which PM method to use
#         bbswitch - new in BB 3, recommended if available
#       switcheroo - vga_switcheroo method, use at your own risk
#             none - disable PM completely

## Section with nvidia driver specific options, only parsed if Driver=nvidia
# Module name to load, defaults to Driver if empty or unset
# colon-separated path to the nvidia libraries
# comma-separated path of the directory containing and the
# default Xorg modules path

## Section with nouveau driver specific options, only parsed if Driver=nouveau

Any idea how to fix this? Please help

I'd try to remove bumblebee completely, and install it again. – Adobe Apr 27 '14 at 17:43
Tried that already, a couple of times. Still shows the same error. – user274780 Apr 28 '14 at 14:05

12.04 might just be too old. Add the X-Updates PPA and then reinstall bumblebee.
