How to place window controls in chromium/chrome to the left side?

Anyone knows how to do it? It doesn't inherits openbox's settings so i tried advices, related to other unity/gnome (maybe chrom* inherits it):

$ gconftool-2 --get /apps/metacity/general/button_layout
close,minimize,maximize:
$ gsettings get org.gnome.desktop.wm.preferences button-layout
'close,minimize,maximize:'
$ gsettings get org.gnome.shell.overrides button-layout
No such schema 'org.gnome.shell.overrides'

But buttons still on the right side. And I still don't want additional useless native decorator.

Looks like you have not enabled setting "Use System Title-bar and Borders".

Go to Settings in Chrome/Chromium > Search for this option and check-mark it.

Update

While above solution will use native window frame, if you want to avoid using that, you can have a look at this answer. If it still doesn't solve the problem, I believe it is something to do with OpenBox which doesn't use Metacity decorator.
