Only use a header bar in GNOME shell

[Khurshid Alam]

Issue:
------
On Ubnunty <=17.04, Nautilus is patched no to show headerbar under Unity. The patch was dropped in Artful due to some issue. I have updated the patch to make it work with Nautilus 3.26.x.

Nautilus will keep using headerbar in all non-unity shell.

Branch:
-------
https://git.launchpad.net/~khurshid-alam/nautilus/+git/unity-test/tree/debian/patches/0002-Only-use-a-header-bar-in-GNOME-shell.patch

Testing:
--------
I asked in https://community.ubuntu.com/t/testing-unity-session-in-18-04/987/20, and the results are satisfying. It is working as intended.

Regression-Potential:
----------------------
None

Is there any flavor which uses nautilus and would like to have that change? Otherwise it would probably make sense to lower our number of Ubuntu specific changes and recommend users who want a traditional menubar to use another file manager (they are some based on nautilus in the archive which don't use headerbars)

@Sebastien

Unity can't work without nautilus, not without making significant changes. Recently we started a community effort to maintain Unity as possible as close to old Unity. See

https://community.ubuntu.com/t/unity-7-continuation-call-for-developers-and-supporters/736

Beside we are already carrying many other unity patches in nautilus (like quicklist, zeigeist, open-location etc) and many other gnome-apps. Why would this be an exception? These patches are quilt patches which can be disabled any time you want.

The original bug was LP: #1711241. On that bug report Jeremy asked me to open a new bug with the patch. So I did.

This is not a "whishlist". :/

Status changed to 'Confirmed' because the bug affects multiple users.

@khurshid, sebastien,

This file manager works very well in unity. https://community.ubuntu.com/t/testing-unity-session-in-18-04/987/23?u=dale-f-beaudoin
Problem is the titles are in the menu bar and not the header.

I do not know if it would be stable in 18.04.

Khurshid, please see LP: #1719322

The Ubuntu Desktop Team was thinking about dropping all of these header bar patches that weren't accepted by GNOME.

Tested patched version of Nautilus and expected behavior of the menubar is working.

But there is another type of possible small bug under "unity-session" for Nautilus.
When the first opened instance of Nautilus is on Home folder and you try to open a second instance with the middle click on the Nautilus icon, nothing happens.

Under "ubuntu-session" there is no such deviation - another Nautilus instance is
normally opened with the middle click no matter first one being opened at the Home folder.

Under "unity-session" with the first instance being opened on the Home folder, second instance can
be repeatedly opened only in two ways:
- by right clik on Nautilus icon and selecting something from context menu
- when the first open instance is opened in any other folder than Home, midlle click
  opens second instance of Nautilus normally

@blue29

That's a separate issue. org.gnome.Nautilus can't be launched like that because 'DBusActivatable=true' is set in /usr/share/applications/org.gnome.Nautilus.deskt
op

Please open a separate bug for that.

That's not something Ubuntu is going to patch over upstream
