Disabling the Alt key from showing the HUD:

  • Install CCSM with sudo apt-get install compizconfig-settings-manager

    enter image description here

  • Start it from the Dash or by typing ccsm from the terminal.

  • Type "Unity" in the filter box on the left, and click on the Ubuntu Unity Plugin:

    enter image description here

  • Click on the <Alt> button the red arrow points to, and then uncheck the Enabled box. Click OK and close CCSM -- the Alt shortcut is now disabled.

  • If you no longer need CCSM, please consider uninstalling it.

    Because it seems newbies often want to play with it once they try it out, and the next thing you know, it crashes, all they have is a blank desktop and they panic :)

    haha, that's exactly what I did. But I agree with Tom, in fixing it I learnt something.

    Is there a way to make Hud only capture the right Alt key, not the left Alt?
