Before Ubuntu 18.04, I could lock my screen by using Ctrl + Alt + L keys, but I cannot do it on 18.04.

Does anybody know what are the shortcut keys to lock screen on Ubuntu 18.04?

  • You can go to setting -> Keyboard, there, you can find all shortcuts of your system. – Codito ergo sum Jan 11 at 9:18

    @PRATAP Thanks for your edit, but there is also an option accept and edit, why didn't you use that option? – Codito ergo sum Jan 11 at 9:33

It's Super+L. Super is usually the key with Windows logo.

You can also change it to something you prefer using the Settings application (go to Devices > Keyboard).
