Powertop

Install the “powertop” package and run it to show what needs to be modified on your computer in order to maximize your battery life.

Note that the recommendation that powertop suggests for the wifi, something like

iwconfig eth1 setpower 5

causes your wifi to get reeeeaaaaallllly slow, so don’t do this change. I have tried it it with a setpower arg of 1 and it works fine and saves power. I have not tried other values.

Enabling Compiz

edit /usr/bin/compiz and do 2 searches for intel then comment out the following line

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

This line blacklists the i965gm x3100 graphics chipset from compiz due to video playing problems (and sure enough, you cannot play videos with Compiz active).

Then from the menu, select System->Preferences->

Appearance then the Visual Effects tab and select Extra.

You can also install the compizconfig-settings-manager module to enable even more insane desktop effects.

Touchpad

To make the touchpad more responsive.

Add the xorg.conf entries first, then install gsynaptic and then reboot (or restart X)

My MaxSpeed is 1.5

Add this to your xorg.conf file. Then restart X (Ctrl-Alt-Bksp). Save any unsaved work before restarting X.

Option “AccelFactor” “0.25”

Sound Volume

The default sound volume is messed up, being set too low. To increase the sound volume, in a terminal, run:

alsamixer

use the left arrow key to go over to the Front bar and use the up
arrow to increase it to 100%.

Playing DVDs

From https://help.ubuntu.com/community/RestrictedFormats

Go to Applications → Add/Remove…
Set Show: to All available applications
Search for ubuntu-restricted-extras and install it.

Install VLC. Totem-gstreamer will not work properly with DVDs

You may need to go to
/usr/share/doc/libdvdread3 and run
$ sudo ./install-css.sh

to install the DVD decrypter codec, but i am not sure.

Reboot and then use VLC to play the DVD.

Sound

Sound does not work out of the box with Gutsy.

Consulting http://ubuntuforums.org/showthread.php?t=577469 yields:

sudo apt-get install linux-backports-modules-generic

Reboot so all changes take effect; you should now have sound

Change amixer settings so the microphone plugging in to the side will work (I haven’t got internal to work yet).
