OpenGL::XScreenSaver is free software you may redistribute it and/or modify it under the same terms as Perl itself. Go to System Settings.Brightness and Lock: enter image description here. This again keeps the design of a screenhack dead simple. This means that no event handling is required by your screenhack whatsoever. The process is sent a SIGSTOP when the unlock screen is displayed, obviously a SIGCONT when it is dismissed, and when the pointing device is moved or the screen gets unlocked XScreenSaver sends a SIGTERM. XScreenSaver handles all user input including exiting and pausing the screensaver. init() of this module checks both of these.

The window ID is passed either via the -window-id option or via the XSCREENSAVER_WINDOW environment variable. Step 1: Download and install MurGee Screen Saver on Windows PC (Windows 8, Windows 8.1, Windows 10 or any other Windows. xscreensaver doesn't seem to have this option. Now I would like to have a digital (numbers) clock and display the date when not in use. This is either a small window mapping to the screen in the preview dialog, or a fullscreen window. With xscreensaver, the screen goes blank when not being used. XScreenSaver tells the hack on startup what window ID the hack shall draw to. What follows is a short description of how it works and what XScreenSaver expects a screenhack to do.
Install it with sudo apt-get install xscreensaver and don't forget to add it to your lxsession/LXDE-pi/autostart file if you want it to start after every reboot. Perhaps xscreensaver is the easiest to set up, as it comes with a graphical config dialog. The dimensions() function returns a list with the width and the height of the currently used window. xscreensaver xautolock lxlock dm-tool etc. In the future it might also handle a minimal set of X events when run in standalone mode (like window deletion requests by the window manager). It will flush output and swap the buffers. The update() function should be called when you finished rendering the frame. The start() function will open the connection to the X server and bind to the window ID or create a new window to draw on (depends on if it was called standalone or from XScreenSaver). if your standalone version comes as an extra binary with keyboard control, which would be useless in a screensaver). This value can be ignored unless you want to make sure that your screenhack cannot be executed outside XScreenSaver (e.g. The init() function will return a true value if a window to draw on has been found, and a false value if a window will have to be created. Read the synopsis for how your program might look.

The author of xscreensaver prefers you to always use the most updated version, so he put a check in his code that sees if your version is more than, say, a year old. It prepares the GL to be used with XScreenSaver. Xscreensaver keeps getting updated by the author, but the newer versions are not automatically updated on that list until the next OS release.
