All the solutions I have researched so far are for obsolete versions of Chrome, or the workarounds were too awkward or involved for most users. I was moved to keep looking. The solution was simple and intuitive (but it required false starts and force quits to realize it with a seemingly frozen keyboard):
If you use a screen saver with password protection, and you leave the computer in full-screen mode after leaving for work (or falling asleep binge-wacthing Netflix), you must enter your password in order to regain control. In full screen there's no visible dialogue box (it's hidden behind the full screen application).
Try first- before clicking on anything, just type in your password. If you see the cursor turn into a spinning wheel, just wait for your password to be verified. Then you will be able to click on the navigation buttons again.
Try second- however, most of the time I have to blindly alt-tab in order to give the password dialogue the focus, so that I can enter my password.(There's no way to tell which application is right behind the full screen application, so you might have to alt-tab and re-enter the password several times. Persevere, this works. there's no need to modify the settings or crawl the code if this works for you.)
The easiest way to prevent this is to avoid leaving the computer in full screen mode, but this is an effective solution if you fall asleep watching Downton Abbey.
I have verified this on Chrome Version 48.0.2564.109 (64-bit) on Ubuntu 12.04 LTS
