The xscreensaver program waits until the keyboard and mouse have been
|
|
idle for a period, and then runs a graphics demo chosen at random. It
|
|
turns off as soon as there is any mouse or keyboard activity. It can
|
|
also lock the screen (immediately, after a longer idle period, or on
|
|
demand.) xscreensaver consists of two parts: xscreensaver itself, the
|
|
``driver'' or ``daemon'', which detects idleness and does locking; and
|
|
the many graphics demos that are launched by xscreensaver.
|
|
|
|
Any X program that can draw on the root window can be used with
|
|
xscreensaver, regardless of how that program is written, or what
|
|
language it is written in, or what libraries it uses. The xscreensaver
|
|
daemon takes care of detecting when the user is idle, locking, and
|
|
checking passwords and all the other book-keeping; all the other
|
|
programs need to do is draw.
|
|
|
|
The benefit that xscreensaver has over the combination of the xlock and
|
|
xautolock programs is the ease with which new graphics hacks can be
|
|
installed. You don't need to recompile (or even re-run) the
|
|
xscreensaver program to add a new display mode, you just change a config
|
|
file.
