Comment 148 for bug 1589401

I also had the issue on a fresh Ubuntu 16.04, the applet not working properly after resuming from suspend.

But I may have something to help here. A few days ago, I didn't had the issue on a previous install, so I tried the two changes I made on that one suspend-related.

First, I enabled hibernation, but it didn't change anything, still the bug after resume.

And then, I installed tlp, basic with no modification, and it now works properly every time.

Hope that may help.
