 How to Enable Screen Lock on Steam Deck's Desktop Mode
+
+I've been using my Steam Deck as a replacement for my ancient laptop, and while using it at work I noticed that there was no lock screen in Desktop Mode. My usual Win+L keyboard shortcut did nothing. I searched online and found that other people were having the same issue. I looked through all of the system settings, and while I was able to find options regarding locking the screen, nothing seemed to allow me to lock the screen on demand.
+
+Interestingly enough, under System Settings -> Workspace Behavior -> Screen Locking, you can set up a timer to automatically lock the screen, and that appears to work fine. So I knew the functionality had to be on there somewhere.
+
+So I enabled SSH, enabled the automatic lock screen and waited for the Steam Deck to lock itself. Then I ssh'd in and saw the command that was being run:
+/usr/lib/kscreenlocker_greet --immediateLock
+
+So I made a .desktop file to run the command, and sure enough it seems to work!
+
+# WARNING!
+Steam's On-Screen Keyboard doesn't show up on top of the lock screen. If your screen is locked, you will need to use a physical keyboard if you want to unlock it without rebooting!
+
+I'm hoping that Steam eventually releases an update that adds lock screen support for desktop mode. Until then, this workaround works for me. I don't recommend setting up an automatic lock screen timer, you don't want to accidentally get locked out of your Steam Deck while using it as a handheld!
+
+# Setup Instructions
+Download the screenlock.desktop file. If you execute it, your screen should lock.
+
+If you want to add it to the Start Menu, copy it to ~/.local/share/applications/ (.local is a hidden folder! You'll have to Show Hidden Files in Dolphin to get there!) Afterwards, it should show up in the Start Menu under Utilities.

+
+If you right-click on it, you can add it to your Favorites for easier access.

+
+Finally, in System Settings you can add a keyboard shortcut to it!

+I hope this comes in handy for people!
