I wish to auto lock the desktop after 10 minutes and have a password protected login screen open up. Power Manager has a light-lock feature but it locks after screensaver and there is no screensaver preference in Lubuntu.
This is for Lubuntu 18.04. I have not tried it on the lxqt desktop.
1) Disable light-locker
sudo mv /etc/xdg/autostart/light-locker.desktop /etc/xdg/autostart/light-locker.desktop.bak
2) Install xscreensaver
sudo apt install xscreensaver
- Set options in xscreensaver-demo
- set xscreensaver to autostart options with -nosplash option
- In Power Manager/Display set toggle to OFF
