I have searched blogs and forums, installed several drivers, but can't find a solution that can provide equivalent video quality as that of Windows 7. Kindly help.

Video quality specially color is too bad while playing with any media player. Configuration details are:

1. Ubuntu - 12.04
2. Intel Corporation Mobile GM965/GL960 Integrated
3. The results of the following commands are

a) sudo lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)

b) find /dev -group video

/dev/fb0
/dev/dri/card0
/dev/dri/controlD64
/dev/agpgart

c) glxinfo | grep -i vendor

server glx vendor string: SGI
client glx vendor string: ATI
OpenGL vendor string: Tungsten Graphics, Inc

d) sudo lshw -C video

I have spent days installing various drivers, and then un-installing but can't come up with a solution. Please help.
