logtom Sorry about that.
run this script to read all the key/values in gsettings
#!/bin/bash
for schema in $(gsettings list-schemas | sort)
do
for key in $(gsettings list-keys $schema | sort)
do
value="$(gsettings get $schema $key | tr "\n" " ")"
echo "$schema ==key=> $key ==value=> $value"
done
done
Save this script (ex: allgset.sh) and provide execute permission and run
chmod +x allgset.sh
./allgset.sh > allgset.txt
you can open allgset.txt file in editor search for Lock or lock and
find the key and set the values like below command
gsettings set <schema> <key> <value>
I found 2 places for lock string in my system
gsettings get org.gnome.desktop.lockdown disable-log-out
gsettings get org.gnome.desktop.screensaver lock-enabled
gsettings set org.gnome.desktop.lockdown disable-log-out false
gsettings set org.gnome.desktop.screensaver lock-enabled true
execute the above and try. If it didn't work revert back to false
search for <Super>l or <Super>L or <Super><Shift>L in the allgset.txt
(I didn't find anything in my System)
you can yous dconf editor too refer algent
