Hi
I have a brand new XPS 13 DE, just installed ubutu 16.04, kernel 4.4.0-24
so I can make some tests.
Indeed there is a problem with CPU. Here is my first test:
* install latest Displaylink driver 1.1.68
* test if it work with my dock D3100 + external HDMI monitor: YES!
* unplug the dock
* reboot (laptop alone, nothing is connected)
* in the terminal, "top" tells me DisplayLinkManager uses between 0% - 0.3%
so this is fine
* close the lid to suspend, re-open to wake up
* now DisplayLinkManager is steadily using 16%CPU !
(with nothing connected) So something is wrong here.
