I recently installed an update. After I restarted I noticed that when I lowered the brightness or volume lower or higher, it would not show the new value in the purple box that would previously come. I'm relatively new to Linux but I know quite a few commands (I'm willing to do terminal stuff).
I've tried restarting but that hasn't worked out. I've realized that when I connect to a new wifi network it shows a different panel (that is now white). Is this a "new feature", or something that I can fix?
I also tested out the different Unity theme Radiance sometime back, but I don't think that's the issue.
Edit:
The output of uname -r:
aparms@aparms-PC:~$ uname -r
4.8.0-36-generic
