[mythtv-users] feature request: plasma burn-in module

[David]

Well, you could write an X screensaver, but I don't think you need to.  
Most Linux distros come with a multiple of screensavers and I'm pretty 
sure that several offer background color cycling.  If not, one should be 
simple to write, and would not require Myth programming at all.  Just 
let the saver kick in on an idle timer like usual.

However you'd probably want to at least script something to disable it 
when playing videos/live TV since you wouldn't want it kicking in while 
watching something.
