Disable nothing and use meta key (aka Super or Windows key)

Hold down Ctrl+Alt+Meta+L and Ubuntu will ignore this for Lock Screen but your application will interpret it as Ctrl+Alt+L.

Disable Ctrl+Alt+T in Ubuntu shortcuts

Go to System Settings -> Keyboard -> Shortcuts -> System -> Lock Screen and hold down Ctrl+Alt+Shift+Z

This will hopefully allow you to reassign the original key combination in another application.

To disable lock screen permanently


gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'


On my dual monitor system the lock screen no longer appears when pressing Ctrl+Alt+L. However the screens saver still kicks in and you have to move mouse, touch a key, etc to turn the monitors back on. Although a password is not required to unlock the screen it might be a bug.

⇧ Locate command is returning too many results Is there a way to install Ubuntu completely on a portable external HDD and boot into it on any computer/laptop?  ⇩
