I installed bumblebee couple times in ubuntu 13.10,12.04 but now it's not working for ubuntu 13.10. I followed the instruction here (including nvidia-319-updates). When i try to run optirun it shows errors.

# 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


Section "Device"
    Identifier  "DiscreteNvidia"
    Driver      "nvidia"
    VendorName  "NVIDIA Corporation"
    BusID "PCI:04:00:0" #changed to 04:00.0 but no luck. So revert back.

At last i found the solution. I am posting it for future reference.

There are two problem.

1. bbswitch
2. nvidia-driver

ubuntu 13.10 is using 3.11.x kernel and bbswitch is not working in 3.8 to 3.11. It's kernel issue(according to blogs) and fixed in >= 3.12. I solved bbswitch problem by upgrading my kernel to 3.12.6. here

nvidia-304, nvidia-319 is not working in ubuntu 13.10. I am telling this because i run my card(740M) with nvidia-319 in 13.04. You have to install nvidia-331. This is a useful reference, how to install bumblebee with nvidia-331.
