XScreenSaver resembles a container that can accommodate any X-window program that can be drawn in the root window as a specific screen saver. Now the xscreensaver gather a lot of beautiful screensaver programs, such as various curves, 3D animation and so on.


Using Glslideshow to make Screensavers

As a drawing front-end program for setting parameters on screen savers executed in the background, it has two main functions, one as editor /. A tool for XScreenSaver files as a tool for demonstrating the graphical patterns that various screen saver processes will perform.
Its main window includes a File menu and two tab pages, the first page to edit the demo list, and the second page to edit the various screen saver parameters. Related features are described below:
1. menu commands
Blank screens Now: Activates the background screen saver process and then randomly demonstrates it.
Lock screens now is similar to the blank screen now, but it will be locked at the same time (even when the program does not set the lockout time), and then you need to type the appropriate password to continue using it.
Kill Daemon: If the xscreensaver process is executed on this screen, kill it.

On the left is a list of various display modes, and the right is where you edit their status.
Demo list: Double-click the list on the left to let you test the specified demo. After the screen becomes black, the program executes in full screen mode. Clicking the mouse again will stop the demo and restore the original screen.
Arrow Buttons: Below the list is a pair of up and down arrows. Click the down arrow to select the next item in the list, and then execute it in full screen mode. The up arrow is the opposite. This is a shortcut for testing all of the display modes.

Verbose: Whether to output a variety of debugging information.
Install ColorMap: Whether to install your own color spectrum when the screen saver is active so that the program can use as many colors as possible.
