Hi all, We've developed a new system using Ubuntu (Gnome) as the platform. The system has a hand-held imaging scanner (akin to a bar code scanner,) and printer. It's quite simplistic, but was a dog to get it 'right'. Anywho, one last problem we're experiencing is the screensaver. We must have it enabled for periods of inactivity, but the scanner does not count as "activity" so it does not disable the SS when scanner triggered, which we'd like it to do. And also, after 5 mins of use the screen saver enables, despite someone scanning/printing furiously away. Apps like Totem (movie player) do something to prevent the screensaver, but short of it disabling the screensaver on open, and then enabling it on close (which is dirty) I cannot fathom how they do it. No C/sh/bash snippets found when searching the WWW. Much obliged for opinions and help.
