I want to have a hot corner that will immediately (and reliably) load my lock screen. Any suggestions?

  • xdotool can do this.. go through man xdotool – PRATAP Jun 5 at 14:46

For what it is worth:

Super+L (Super is the Windows key on PC, or the command key on Macs) locks your screen.

I always have the screen blanker off, but it still activates as I press these keys.


System Settings > Brightness & Lock:

Turn screen off when inactive for: Never.

Lock: ON
Lock screen after: 30 seconds.

    It says nothing about the hot corner part, the feature OP is looking for. – pomsky Jun 5 at 14:55

    Yes? And how come this would not be still a valid answer? Maybe OP didn't know about this. – Hannu Jun 5 at 15:06

    Thanks @Hannu - you are correct in that I did not know about this. Makes the hot corners no longer needed – Shamoon Jun 5 at 15:30

    +1 for addressing the XY problem, though in spirit of SE perhaps the other answer should be the accepted one. – Thebluefish Jun 5 at 22:52

First you need to install a GNOME shell extension called CustomCorner to be able to activate hot-corners.

Then open the extension's preferences and choose a corner, and select 'Run Command'.
enter image description here

In the command box, use the following

dbus-send --type=method_call --dest=org.gnome.ScreenSaver /org/gnome/ScreenSaver org.gnome.ScreenSaver.Lock

Alternatively, you can use

gnome-screensaver-command --lock

if you have the gnome-screensaver package installed.

For what it's worth:

In Kubuntu 18.04 (Ubuntu with the KDE 5 desktop), this is built in:

System Settings > Workspace - Desktop Behaviour > Screen Edges - each of the screen edges and corners can be set to various actions one of which is Lock screen.

    This question is tagged as using Gnome, so I'm not sure why you answer this for KDE. – Mast Jun 7 at 11:07

    @Mast Why does it matter? Someone else might stumble upon this post because of its similarity and find it useful. – Sloth Armstrong Jun 7 at 18:58
