Public bug reported:
I got very HIGH CPU usage ONLY when computer going IDLE.
Again, I have NO PROBLEM during work (video playback, moving windows slowly or
fast, no lag, everything is perfect),
BUT when I am out of computer: 20 secs after display fades out CPU fan starts
and works heavily (my colleague started to complain due to my CPU fan in quiet
environment).
Data:
- Fresh install of Ubuntu 15.10 (plus some other non-desktop or gnome related
packages)
- All energy consumption related settings are default (I have not changed them
till now).
- Laptop: ACER Aspire V3-371
- CPU: Intel Core i5-5257U
- GPU: Intel Iris grapics 6100
- Display: 1920x1080 internal laptop display, no other display ever plugged in.
- 8G RAM
- 120G SSD
First few lines of top immediately after going on from IDLE:
