cons.saver - general-purpose Linux console screen save and restore server
Invoke this helper program with the Ctrl-o key combination to save and restore the user session on the screen.
cons.saver takes only one argument, the TTY NAME from which the system will save and restore.
Cons.saver does not need to be invoked by root. It only needs read and write access to /dev/vcsa*, which is a priviledged operation. You
should create an unprivileged user, make cons.saver setuid to that user, and assure that all the vcsa* are owned by that user too.

XSetScreenSaver - set the parameters of the screen saver.
XSetScreenSaver(display, timeout, interval, prefer_blanking,
int timeout, interval;
display Specifies a connection to an X server; returned from XOpenDisplay().
timeout Specifies the time of inactivity, in seconds, before the screen saver turns on.
interval Specifies the interval, in seconds, between screen saver invocations. This is for intermittent changes to the display, not
Specifies whether to enable screen blanking. Possible values are DontPreferBlanking, PreferBlanking, or DefaultBlanking.
Specifies the current screen saver control values. Possible values are DontAllowExposures, AllowExposures, or DefaultExposures.
XSetScreenSaver() sets the parameters that control the screen saver. timeout and interval are specified in seconds. A positive timeout
enables the screen saver. A timeout of zero (0) disables the screen saver, while a timeout of -1 restores the default. An interval of
zero (0) disables the random pattern motion. If no input from devices (keyboard, mouse, etc.) is generated for the specified number of
timeout seconds, the screen saver is activated.
For each screen, if blanking is preferred and the hardware supports video blanking, the screen will simply go blank. Otherwise, if either
exposures are allowed or the screen can be regenerated without sending exposure events to clients, the screen is tiled with the root window
background tile, with a random origin, each interval seconds. Otherwise, the state of the screen does not change. All screen states are
restored at the next input from a device.
If the server-dependent screen saver method supports periodic change, interval serves as a hint about how long the change period should be,
and a value of zero (0) hints that no periodic change should be made. Examples of ways to change the screen include scrambling the color
map periodically, moving an icon image about the screen periodically, or tiling the screen with the root window background tile, randomly
