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
# sudo -s
# echo "options iwlagn led_mode=1" > /etc/modprobe.d/wlan.conf
# reboot
Bravo! I really liked the logic 🙂
