Comment 243 for bug 1568604

Tried with gnome-screensaver and xscreensaver

They work. I think the problem is light-locker

I'm trying to replace light-locker with one of them (at startup and preferences menu).

In fact, Lubuntu 12.04 LTS used xscreensaver

But Lubuntu 14.04 LTS uses light-locker

Test to do...

sudo apt-get install gnome-screensaver
sudo apt-get install xscreensaver

Ctrl+Alt+T

light-locker-command -l ----> Mouse cursor lost

killall light-locker

gnome-screensaver-command -l ----> OK

killall gnome-screensaver

xscreensaver ----> Needs daemon mode

Crtl+Alt+T

xscreensaver-command -l ----> OK

killall xscreensaver
