For a while now, I was able to use the instructions from one of the comments in this answer to align Chromium's Close, Minimize and Maximize buttons to the left of the browser window.
However, in Chromium 52.0 on 16.04 the button layout remains at Minimize, Maximize and Close on the right.
I've entered this command in the terminal with no success.
gconftool-2 --set /apps/metacity/general/button_layout --type string "close,minimize,maximize:"
How can I move Chromium's button layout from right back to left?
