From what I understand, 3.6.3 has the notable feature of implementing built-in global menu support for Ubuntu. Currently, I’m using 12.04 LTS and have manually installed the DEB files (since neither the official repositories nor the PPA has it yet). After installing, the menu bar is still in the window instead of showing up as a global menu. Restarting does nothing, either.
Did I misread the release notes? Is built-in global menubar support not currently possible with the LTS release of Ubuntu? If it is possible, what specific steps must I do to get it working (without upgrading to 12.10)?
