Comment 2 for bug 977056

Hi Sebastien,

Version of Unity: 5.8.0-ubuntu2
https://bugs.launchpad.net/ubuntu-power-consumption/+bug/917210.......woops, that's a lot of traffic :-)

I'm not familiar with the underlying structure of both unity versions. As far as I know, unity 2d is written in Qt using a modified metacity and unity 3d is a compiz plugin. I would gladly go on bug-hunt if I knew where to start.

My measurements where not really fancy actually:
I have measured power use with an old school cross-coil power meter, and I timed with a clock how long the battery did approximately last on idle for both unity 2d and unity 3d under same conditions.

I was curious because the lifespan of the battery was incredibly shorter than under another well known OS.

I will read the posts on the link you send me.....possibly I will get some clues there...

Thanks for your reaction.
