Ubuntu – Why are many options in gnome-tweak-tool inaccessible

gnomegnome-tweak-tool

When I run gnome-tweak-tool, a lot of the options are locked. In particular, I'm talking about the gnome shell theme, and the gnome shell extensions. They all have a "warning" type icon with an exclamation point next to them.

I am not logged in to a unity session or Gnome classic, just regular "Gnome"

Gnome in the login menu is gnome-shell. You need to have gnome-shell-extensions-common and gnome-shell-user-theme installed. There are a number of ways to do this, one is to use

https://extensions.gnome.org/

to add the different extensions for your GS version. Another way is to add one of the PPAs that are available! such as webupd8's... 

sudo add-apt-repository ppa:webupd8team-gnome3/oneiric

editor's note: oneiric is EOL; adding this repository will probably break your system

If your extensions are not loading properly then check that your extension and gnome-shell version are the same :-) 

sudo -H gedit /usr/share/gnome-shell/extensions/user-theme@gnome-shell-extensions.gcampax.github.com/metadata.json

and look for shell version. You can edit the extension version to match your own, e.g. 3.2.1.
