The next article in the run up to releasing 1.4 will look at the new Wake On Lan (WOL) feature of Xibo.
[](/content/images/2012/05/wol-edit-display.jpg) WOL Settings on the Edit Display Form There has been a lot of interest over the years Xibo has been running for a solution to be “green”, “save power” and generally not have the Xibo display screen solution on unnecessarily. The Xibo project has been very keen to put these things in place, and 1.4 will contain a number of measures to make these wishes a reality.The WOL function is intended to be used for display clients that are addressable by the server, by this we mean that there has to be a clear addressable network route between the server and the client that needs to wake up. It is also required that WOL is turned on in any necessary settings on the client PC.
The WOL configuration happens on a display by display basis from the Edit Display form. Each display has new settings for:
Once the display has these settings it can be woken up in 2 ways:
In addition to the WOL now function, the Xibo maintenance module has been altered to send a WOL packet to any display which has a “Wake On LAN Time” specified. It will only send the command once, as the time window is passed.
The maintenance script has to be running for this to work correctly. Maintenance instructions can be found on the wiki.
There are a few different options for putting the client to sleep – such as a scheduled task. However, the next article in this series will look at an option built into Xibo. The “Shell Command” module.
We hope you will find this new functionality useful! As always comments are always welcome over on Launchpad Answers.
