Comment 58 for bug 1778011

Tested on Dell Precission 5520 with Ubuntu 18.04. This suffer from a consistently high power usage in the Intel (Power saving) mode.

Proposed Packages install fine. After reboot switching Prime profile did not seem applied with logout+login. Reboot was required. After a further 'apt upgrade' which pull in some new updated the Prime profile switch work with just a logout+login. I assume I got a gdm3 update which was required.

Looking at power graphs from the 'Power Statistics' tool i am getting much better power usage (first time under 10W). Thanks for the work. Will add a second comment if anything crops up after more usage.
