Start mining when the screensaver is activated
Hi there
I just hacked together a little something that polls dbus and starts/stops mining when the screensaver comes on/off.
My editor removes whitespace at line ends so there's a few occurrences of that in the diff. This will of course only work on systems with dbus. Since I'm really not a python programmer I'd like to leave the task of making this safe for other platforms (e.g. disabled) and maybe adding a console switch to (de)activate this feature or add a checkbox in the gui and whatnot to you.
For my purposes, this is sufficient but I hope it might be useful to others and so am trying to contribute back.
Have fun!

Nifty, thanks for the contribution! I'm not sure when this will make it into a release, but I'll keep it in the issue tracker for now in case anyone else wants to use it :)
Why don't you fork it and give it a file name and a good description. At least that's what I did when I tried to put up an update the servers list . I'm trying to find an issue on here and it seem to have disappeared since I noticed it. I hope you can find a way to wind this into a screen saver if not directly into guiMiner.
