If your battery is running out too quickly you can enable laptop-mode-tools. It's installed by default but it's oddly not enabled. Just edit the /etc/default/acpi-support file with the following option:

ENABLE_LAPTOP_MODE=true

To set laptop-mode-tools you can read this post or go to the project's page.

After setting it up, restart laptop-mode-tools with this command:

/etc/init.d/laptop-mode restart

There is a specific workaround in order to adjust the brightness on the Samsung netbooks.

If you would like your installed Web-App links to launch in Google Chrome instead of Firefox, there is an easy fix. *Make sure you have Google Chrome installed before starting.

• Go to the Preferences section, and select Main Menu
• Go to the Internet section, and select the Web-App you wish to open in Google Chrome.
• Once highlighted, click Properties
• In the Command field, delete what is there and change it to /opt/google/chrome/google-chrome -app=“http://abc123url.com/; where abc123url is replaced with the domain of the webapp.
• Hit Close on the Launcher Properties, and then Close again on the Main Menu program.

You application should now open with Google Chrome. Feel free to hit F11 to make it full screen. *Note that as of December 16, 2009, Google Gears are not working by default.

What's more, Google Chrome will create application shortcuts for any webpage and place them under “Internet” in the application menu from within the browser.

The fan in the AAO is always on by default. It can be controlled by giving some options to the acerhdf kernel module. This can be done by creating a file /etc/modprobe.d/acerhdf.conf with:

sudo nano /etc/modprobe.d/acerhdf.conf

Then enter the following:

options acerhdf kernelmode=1 interval=10 fanon=60000 fanoff=52000

This will turn the fan on when the CPU temperature reaches 60 degrees Celsius and turn it off when it is down below 52 degrees.

The sensors-applet can be installed and added to the panel to visualize the CPU temperature. Install the applet by running the command:

sudo apt-get install sensors-applet

Right-click on the top of panel and choose Add to panel… and select Hardware Sensors Monitor. Then reboot the computer to make all sensors available for the applet. If you have problems at boot time with the hddtemp application that is pulled in by the sensors-applet, you can simply remove it with:

sudo apt-get remove hddtemp
