I have a custom keyboard setup that I use, with 3rd level keys that appear when you press the Alt Gr button and another key.

The problem is that I installed Ubuntu 14.04 and now the Alt Gr key is used for menu shortcuts instead, so I can't use it any more for my purpose.

Does anybody know how to fix this? I don't mind losing the shortcuts.

I found a workaround for this bug here on Ubuntu Forums

To disable mnemonics you should create (if it doesn't already exist) ~/.gtkrc-2.0. This file should contain the line gtk-enable-mnemonics = 0 (you can add other GTK settings if you'd like). Then, restart for the changes to take effect (you may be able to log out then log in instead).

    This didn't work for me on Nautilus on 14.04. I posted an answer to a similar question here askubuntu.com/a/569303/11929 Jan 5, 2015 at 20:54
