Hi All,

For the "Improved Laptop Battery Life" feature:
https://fedoraproject.org/wiki/Changes/ImprovedLaptopBatteryLife

I'm working on for Fedora 28 I would like to also try and enable
Panel Self Refresh on laptops with Intel graphics, some quick tests
have shown this to save another 0.5W (when idle / nothing on the
screen changes). This is currently off be default because it is
known to cause issues on some devices. So I think we will probably
need a white- or black-list. But first we need more data on this.

If you can spare 10 minutes, please see my blogpost for how to test
this and send me a mail with the info request in the blogpost:

Regards,

Hans
