Description Elad Alfassa 2011-10-06 13:51:58 UTC 
I got a lot of "No backlights were found on your system" in my ~/.xsession-errors and

<elad661> I jsut don't understand one thing: if the power plugin saw there is no backlights when it first tried, why does it keep trying?
<hughsie> that's also a valid question
<hughsie> backlights can't really come and go
<elad661> Yeah and probbing again and again is just a waste of resources

    So that we can use it in the plugin itself.
