Comment 52 for bug 1286910

I have this bug on Ubuntu 18.04 with Gnome. My keyboard layout is ["en", "gr"].

As a workaround I am using the following bash script that changes the keyboard layout to the first language in the keyboards layout list, i.e "en" (index "0" in inputSources), before activating the gnome-screensaver. I am running this script using a custom keyboard shortcut, set to "Super + L", after deactivating the default one.

Bash script:

#!/bin/bash
gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell \
--method org.gnome.Shell.Eval \
"imports.ui.status.keyboard.getInputSourceManager().inputSources[0].activate()"

gnome-screensaver-command -l
