There are many reasons your trackpad might not work. can you give more details, such as what you were doing when it stops and how often this seems to happen? Please also state the version of Ubuntu and MacBook Air you are using. – Chan-Ho Suh May 18 '12 at 6:54

  3. sudo apt-get dist-upgrade
  4. sudo reboot
