Running Compiz-Fusion in Lenovo Y410 with LinuxMint 4.0 codename Daryna

My laptop (Lenovo Y410) comes with the integrated Intel GMA X3100 GM965 video card. When I installed LinuxMint Daryna and tried to enable Desktop Effects (Preferences > Appearance), error message was thrown stating "Desktop Effects could not be enabled".

Although the correct video driver was installed out-of-the-box, Compiz-Fusion would not work. After a little research, I found out that I needed to comment out
the following line (that is, put a “#” in front of it) on the
“/usr/bin/compiz” file:

T=”$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12″ # intel 965

So, in the end it should look like this:

#T=”$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12″ # intel 965

This is the case because the Compiz developers decided to black list
this card for the time being due to some limitations with the current
Intel driver. I think this is related to video playback, although I
have not had any problems. I guess if I do, I will simply disable the
special effects temporarily to get around the issue.

Bash script to automate compiling ALSA in Ubuntu

Here are the scripts (for any kernel, not just 2.6.22):
