Hi Praveen,

Have a look at your syslog, it says:

Aug 16 18:27:15 bhisma bumblebeed[2132]: Module bbswitch could not be loaded (timeout?)
Aug 16 18:27:15 bhisma bumblebeed[2132]: No switching method available. The dedicated card will always be on.
Aug 16 18:27:15 bhisma bumblebeed[2132]: /usr/sbin/bumblebeed 3.2.1 started

The nouveau driver does not seem to support your graphics card either:

Aug 16 16:00:49 bhisma kernel: [    5.924560] nouveau: probe of 0000:01:00.0 failed with error -22

You are running a pre-compiled mainline kernel I guess:
Linux bhisma 3.8.3-030803-generic #201303141650 SMP Thu Mar 14 20:51:08 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

...though you do not have the corresponding kernel headers installed
(from bumblebee-bugreport):
=== Modules information ===
ERROR: Module bbswitch not found.
ERROR: Module nvidia not found.
ERROR: Module nvidia-current not found.
filename:       /lib/modules/3.8.3-030803-generic/kernel/drivers/gpu/drm/nouveau/nouveau.ko

Try installing the linux-headers packages associated with the kernel image.

Regards,
Peter
