@ -86,6 +88,15 @@ format: rrggbb (i.e. ff0000 is red)
If an image is specified (via -i) it will display the image tiled all over the screen
(if it is a multi-monitor setup, the image is visible on all screens).
.TP
.B \-p, \-\-pointer
If you specify "default",
.B i3lock
does not hide your Mousepointer.\n If you specify "win",
.B i3lock
displays a hardcoded Windows-Pointer (thus enabling you to fuck with your
friends by using a Screenshot of a Windows-Desktop as a locking-screen).
