I am using 64 bit ubuntu 13.04 on a system running optimus technology - Nvidia 635M and an intel integrated card.
Recently came across this article for Intel Linux Graphics Installer:
http://networkedblogs.com/LHlmO
Now I am wondering if I need this installed? If yes, then would also like to know what graphics drivers are currently running the intel card on my system then?
UPDATE - Per Qasim's response tried installing, but even after adding the two keys provided on their website, Software Center gives me the below warning:
Lintian check results for /home/charlie/Downloads/intel-linux-graphics-installer_1.0.1_amd64.deb:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_IN.ISO8859-1"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
E: intel-linux-graphics-installer: malformed-deb-archive found 4 members instead of 3
Let me know why am getting this message and what it means?
Yes you need to install Intel Graphic Driver
The answer is
It has Intel Hardware Acceleration For Intel 3D ( VA-API ).
( VA-API ) also save battery power, I have done lots of testing so i will recommend to install Intel drivers. https://01.org/linuxgraphics/downloads
For Vmware user's 3D acceleration is ON by default and you don't need to do any tweaks for 3D acceleration
You check full details on ( VA-API ) on my answer, You can install it manually check my answer VA-API (Hardware Acceleration For Intel / AMD GPUs), But intel drivers updated VA-API package.
