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

3) Configure

  • Set options in xscreensaver-demo
  • set xscreensaver to autostart options with -nosplash option
  • In Power Manager/Display set toggle to OFF
  • Thank you so much. I read good things about iLock and xautolock but that requires some scripting. Next time I will use the full Ubuntu district. – user711393 May 16 at 3:24
