After few of tweakings, I doesn't have HUD anymore.

Normally (on another computer):

But it doesn't appear at all (on my computer):

Indeed, the ALT key call the menu of focused app. So, as the consequences:

  • I can't do Alt+Tab Windows Switching
  • I can't call Unity command prompt (Alt+F2)

Note: but I still can call Terminal (Ctrl+Alt+T).

My HUD service was on:

prompt # locate hud | grep usr | grep service
/usr/lib/indicator-appmenu/hud-service
/usr/share/dbus-1/services/com.canonical.hud.service
prompt #

I have set HUD shortcut again on System Settings > Keyboard > Shortcut > HUD and Alt L. But the problem still exist. It is annoying problem that doesn't solved by just unity --replace or unity --reset or by reinstalling indicator-appmenu (I've done them all, times). I have read some questions about similiar topic but no one same with this. Any help will be very appreciated.

Thank you.

You may be able to restore things by opening Compiz-Config-Settings-Manager. Find the button for "Unity Plug In". On the first page "General" is a setting for "Key to show the HUD when tapped". If you don't have CCSM, install it with sudo apt-get install compizconfig-settings-manager. –  Jos Apr 14 at 12:38
