Hi,
I wish to have a screensaver.
Thanks ahead for recommendation.
Below are some background info.:
lightdm                                               install
lightdm-gtk-greeter                           install
xfce4                                         install
xfce4-panel                                   install
xfce4-session                                 install
xfce4-settings                                        install
xscreensaver doesn't work for me cause it won't recognize the password
due to I use the dovrak layout. To me, seems the reboot is the only resort.
       
You may be pleased to hear that this has been reported as bugs #644534
and #683257.
In future, you may try switching to a virtual console and running
"xscreensaver-command -display :0 -exit" (though you may need to fiddle
with xset permissions, YMMV). Alternatively, just restarting lightdm
should work, too.
     
There are lighter options than xscreensaver, :-)  Such as xautolock +
xtrlock, or xautolock + any other light locker...
