Somehow I have managed to zoom the text size in Nautilus on Ubuntu 16.10, probably because I couldn't originally change the screen resolution and everything was tiny. Now I can't remember how I did it and cannot undo it.
It is not effected by the text-zoom setting in system settings. It also doesn't change when I zoom the icon size in and out. I've tried Unity Tweak tool and CCSM to no avail. I've also tried resetting Unity to defaults.
I eventually gave up and installed Nemo instead. When I set Nemo as the default, Nemo got zoomed text, and Nautilus became normal.
There must be a setting somewhere that I am missing. Any ideas?
