It can also prevent -the screensaver from activating when a fullscreen window is in use (e.g. -while watching a movie).</p> -<p>Multiple joystick devices can be monitored. By default, jsmond -monitors up to 16 devices, named /dev/input/js0 through js15. -These devices don't have to actually exist: they can come and go -as joysticks are plugged in and unplugged.</p> -<p>Every <em>interval</em> milliseconds (250, or whatever <strong>-i</strong> is set to), jsmond -checks to see if there's been any activity on any of the devices it's -monitoring. If so, it sends a fake mouse movement, keystroke, or mouse -button click, which the screen saver will see as activity.</p> -<p>It's recommended to let jsmond find the joysticks itself. However, -you can pass one or more device names (or just numbers) if the default -doesn't do the right thing for you. In this case, only these devices -will be monitored (no search is done).</p> -<p>jsmond should be started from your <strong>.xinitrc</strong> or whatever X startup -script your window manager or desktop environment uses. By default, it -will exit when the X server does. There's no PID file: use "pkill jsmond" -if you need to kill the daemon.</p> -</div> -<div class="section" id="options"> -<h1>OPTIONS</h1> -<table class="docutils option-list" frame="void" rules="none"> -<col class="option" /> -<col class="description" /> -<tbody valign="top"> -<tr><td class="option-group"> -<kbd><span class="option">--help</span></kbd></td> -<td>Print usage summary</td></tr> -<tr><td class="option-group"> -<kbd><span class="option">-i <var><interval></var></span></kbd></td> -<td>Interval to check for activity.

All 3 modes -(keycode, mouse click, and mouse motion) work with xscreensaver. -xlock doesn't respond to mouse motion, so use the keycode or click -modes with it.</p> -<p>jsmond can monitor up to MAX_STICKS joysticks. This is a compile time -constant, normally set to 16. See the <strong>--help</strong> output to find out -the compiled-in default.</p> -<p><strong>joydev</strong> arguments can be either a path to a device node (e.g. -<em>/dev/input/js0</em> or similar), or a number, which will have the default -device basename prepended to it. This is normally "/dev/input/js", but -can be changed via the <strong>-d</strong> and <strong>-j</strong> options. Note that (currently) -all the joystick devices have to be in the same directory for jsmond -to detect hotplug events!</p> -<p>Note that it's <em>not</em> an error to give nonexistent joystick device names. -jsmond will wait for devices to come into existence (e.g. as created -by <strong>udev</strong>).</p> -<p>If the screensaver is configured to lock the screen, and it has already -done so, pressing a joystick button/direction will just bring up the -password dialog, same as pressing a key or mouse button would.</p> -<p>jsmond depends on the XTest extension being present in the X server. If -you get a "X server doesn't support XTest extension" error, see your X -server documentation to find out how to enable XTest.</p> -<p>The fullscreen window monitoring has only been tested on a system with -a single monitor, and may not work properly in multi-head environments.</p> -</div> -<div class="section" id="exit-status"> -<h1>EXIT STATUS</h1> -<p>Without the -D option, the exit status is 0 (success) if jsmond -successfully forked into the background.</p> -<p>A non-zero exit status means an error in the command line arguments, -or else fork() failed.
