I've just installed the Greybird theme from Ubuntu Software Centre.
But it is not available for selection in the Appearance settings. Only the standard themes (Ambiance, Radiance, and High Contrast) are shown.
It is definitely installed:
carl@number8:~/$ dpkg --list | grep -i greybird ii greybird-gtk-theme 1.9.4-0ubuntu2 all Greybird GTK2 and GTK3 themes
Does installing a theme via Software Centre not actually install it ready for use?
A search around this site shows that in earlier versions of Ubuntu, theme installation invovled things like :
- Knowing the difference between GTK, GTK2, GKT+, GTK3, etc.
- Unzipping an archive and copying the contents to
- Installing and running Unity Tweak Tool.
- Adding PPA repositories
- Assorted command line trickery
I have installed the theme using the Tweak Tool, but I can't help thinking that this seems like something of a hack - not the sort of thing I'd expect from an otherwise very slick and polished distro like Ubuntu.
What is the correct way to add a theme to Ubuntu 15.04?
If the three pre-installed themes are the only officially supported themes, then why is this?
I think my actual question is not so much how to install a theme, but why is it not as simple as a few clicks on a GUI? i.e. Here's a list of available themes - click one and it will be downloaded and installed (c.f. Linux Mint). Is this a deliberate design policy, an oversight, or still on a to-do list?
