gnome-tweak-tool version 3.24

more addition:
i had installed freshly just before this fresh install, it working smoothly but i haven't check the version of gnome-tweak-tool at that time, so maybe it's a new version bug? or something else i did wrong at this time?

the above patch tests that gnome-shell is actually running before binding to the widget.

How to use the patch? I mean what the step is ?

[Jeremy Bícha (jbicha)]

David, thanks for the patch. I am uploading to zesty now for you. I am unsubscribing ubuntu-sponsors. Feel free to resubscribe if you have something else that needs sponsoring.

Usually, GNOME developers prefer patches to be in git format-patch format with the GNOME bug number in the long description part of the commit message. That way the patch can be directly applied to their git branch.

There is a git-bz tool that most GNOME developers use that might be helpful:

This bug was fixed in the package gnome-tweak-tool - 3.24.0-0ubuntu2

---------------
gnome-tweak-tool (3.24.0-0ubuntu2) zesty; urgency=medium

  * Add launch-in-non-gnome-shell-environments.patch:
    - Fix 3.24 regression that prevented Tweak Tool from starting when
      GNOME Shell isn't running (LP: #1678420)
