I was trying to figure out difference between
gnome-screensaver-command -a
and
gnome-screensaver-command -l
According to the gnome-screensaver-command
man page...
-l, --lock Tells the running screensaver process to lock the screen immediately
-a, --activate Turn the screensaver on (blank the screen)
For me in both the cases it generated the login screen.Can some one outline the difference in the two things??
