Ubuntu is one of the most popular Linux distributions. Many people are under the mistaken impression that a Microsoft wireless mouse and keyboard will not work under Linux. Although each Linux installation is a little different, in most cases installing and using a Microsoft wireless mouse under Linux is very easy.
Open your wireless mouse if the batteries aren't already installed. Some mice have a catch on the bottom that secures the top cover of the mouse. For other mice, simply slide the top cover backward to release it from the mouse base.
Install batteries. Make sure the batteries point in the direction indicated by the illustration inside the battery compartment.
Put the cover back on the mouse. Look at the bottom of the mouse. You should see a red LED light shining from a hole. If you don't, click a mouse button. If the LED doesn't come on, check the batteries. If they are installed correctly, replace them with a different pair of batteries. If this doesn't cause the light to come on, your mouse may be broken.
Plug the USB base station into a USB port on your computer. Some USB base stations have an LED that flashes as it looks for a compatible mouse, others may not. Wait about 60 seconds for Ubuntu to fully recognize the USB base station.
Press the button on the base station. This will put the base station into pairing mode. On some base stations, an LED will flash when it's in pairing mode.
Press the "Connect" button on the bottom of the mouse to pair the mouse to the base station. When paired, the LED on some base stations will go out.
Restart your system. In most cases, your windowing system won't formally recognize inputs from your wireless mouse until your system is fully restarted.
