Send Mac to sleep with external screen and closing the lid (Yosemite)

I had the problem of my Mac not going into sleep when external screen is connected and closing the lid. Luckly I came across this advice which indeed, did the trick:

1. Disable external Monitor
2. Type `sudo nvram boot-args=”iog=0x0″`
3. and restart

Voilà!

Update: With Yosemite you need to type:

`sudo nvram boot-args=”niog=1″`
