KDE X11 ScreenSaver SuspendScreen

KDE X11 event-script to have different screen-timeouts when session is locked vs unlocked

1. The Problem

By default KDE will lock the screen after the time specified in Workspace > Workspace Behaviour > Screen Locking > Lock screen automatically > After x minutes.

And the screen is turned off after the time specified in Hardware > Power Management > Energy Saving > Screen Energy Saving > Switch off after x min.

Unfortunately when the screen is locked, even when done manually using the Shortcut (by default CMD/WIN+L), the screen-timeout is still x min which i think is unnecessary (e.g. i went for lunch and lock my screen, knowing i wont be back soon).

This script aims to fix this.

2. The Fix

Adding a script to notifyrc as event makes it possible to change settings when screen-locking begins.

When the screen is locked, the script will change the screen-timeout to a custom-value in the config ~/.config/powermanagementprofilesrc (or a default of 10s).

This is done, so even after the System wakes up and activates the screens e.g. when mouse is moved, but no unlock is done, the screen begins to sleep quickly again.

After a successful unlock, the value from the config is reapplied.

3. How to install/remove

3.1. Automatically

3.1.1. Install

Run the Makefile with install.

make install

3.1.2. Remove

Run the Makefile with remove.

make remove

3.2. Manually

3.2.1. Install

Place the file event_screensaver to a bin-location, for a local user this is typically ~/.local/bin/ and make it executeable.

In Settings under Notifications > Applications > Configure > 'Screen Saver' > Configure Events... for event locked & unlocked, enable Run command and add your script-location for event_screensaver and the event triggered.

Example:

Screen locked
Run Command: ~/.local/bin/event_screenSaver locked

Or update/create the config-file directly under ~/.config/ksmserver.notifyrc similary to the file found in this repository. Then restart or reload KWin.
