How do I disable automatic screen locking in Xubuntu?
light-locker is the new screen locking program in Xubuntu 14.04. If you disable light-locker, it should stop locking your screen.
How to disable lightlocker
- Go to settings manager > session and startup > application autostart and disable light-locker, which is titled “Screen Locker (Launch screen locker program).”
- Reboot your machine and it should stop locking. Alternatively, start up Terminal with Ctrl+Alt+T and run
killall light-locker.

One more solution - start a program below:
/usr/bin/light-locker-settings&
and shift the Enable light-Locking slider to the OFF position, then hit Close.
This panel contains two Screensaver sliders as well.
On my Xubuntu 14.04 install, even when I had Light Locker completely disabled, my screen still blanked after about ten minutes. The solution to my problem was to run the following command:
sudo xset s 0 0
Make sure you run this command from your desktop session and not through an ssh session, or the DISPLAY variable will not be set and this command will not work.
