How to speed up the transition to sleep mode?

Question

mint

Hello, I work under Linux Mint 17.2 (already updated to 17.3) kernel 3.19.32 (Tried on 4.2 and 4.3)
The problem is that the first one! the transition to sleep mode is always long about 10 minutes. All subsequent normal, 30-40 sec.
Prompt, with what it can be connected?

Answer 1

I found the answer myself, as it turned out, you need to edit the config file to switch to sleep mode more...
