My most frequent issue is with hildon-desktop, over time it slowly ramps up its CPU usage and becomes a battery-killer. I haven't been able to determine the exact cause (widget?) yet.

In my tests, the command above has a positive effect in such cases, but doesn't completely correct the problem. On a hunch I tried the exact same idea, but with hildon-desktop instead of hildon-home, and up to now it has proved very effective...
