Ubuntu 11.10 is great OS but it has some things to change, especially if you want to work on a laptop.

The first one is the battery drain, if you don't use any tricks Ubuntu can drain your battery instantly. So I use a fantastic applet to reduce the power consumption:


Jupiter is a light weight power and hardware control applet for Linux.  It is designed to improve battery life of a portable Linux computer by integrating with the operating system and changing parameters of the computer based on battery or powered connection.


Additionally, Jupiter provides quick access to some of the commonly needed hardware controls like screen output and resolution, WIFI, and bluetooth.


If you use Linux on a portable computer, let Jupiter take the effort out of going mobile.

In the following few lines I'll show you how to install jupiter on Ubuntu 11.10

 

sudo add-apt-repository ppa:webupd8team/jupiter

sudo apt-get update

sudo apt-get install jupiter


sudo apt-get install jupiter-support-eee


 
Now you can go to the jupiter web site to view how to use it.
 


Another tedious problem is the wifi led blinking

On my Laptop, linux  uses the iwlagn module for the wifi interface (Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection). It is very simple to disable the wifi led blinking, simply type the following commands in a terminal window:

# sudo -s
# echo "options iwlagn led_mode=1" > /etc/modprobe.d/wlan.conf
# reboot

When the system will be up again, the wifi led blinking shoud be disabled…
