I found the clicking the screen every X minutes method was sub optimal so I went a different route. If the Xibo team could integrate this type of functionality (and a 64-bit Windows client and CefSharp alternative 
) it would really improve the usability of Xibo. I want to try to beta Linux client.
Files deployed via GPO, and script executed via scheduled task GPO.
This effectively “disables” the taskbar entirely as I found even autohide doesn’t work reliably. It also closes the start menu automatically if it opens in addition to checking and forcing the Xibo client on top every 5 seconds. If you need to make changes to the computer, ALT+F4 the Xibo client window and then you should be able to use the start menu or open Task Manager, etc.
