I played a bit more and found out a few bits:
- Changing "Style" in XFCE's appearance switches the theme
for both GTK+ 2.x and 3.x, no matter what key "gtk-theme-name"
of /etc/gtk-3.0/settings.ini and ~/.config/gtk-3.0/settings.ini say
though these files are read according to strace
- The GTK+ 3.0 engine for Clearlooks (libclearlooks.so) seems to be
provided by both
A) x11-themes/gtk-engines-clearlooks-2.91.5 (gnome overlay)
B) x11-themes/gtk-engines-2.91.1 (gnome overlay)
at different locations:
A) /usr/lib64/gtk-3.0/theming-engines/libclearlooks.so
B) /usr/lib64/gtk-3.0/3.0.0/engines/libclearlooks.so
GTK seems to looks for (A) only according to strace.
- Neither package A nor B provide a file
/usr/share/themes/Clearlooks/gtk-3.0/gtk.css
which is required to even activate the Clearlooks engine.
To active the engine, put the line
* { engine: clearlooks; }
in. Expect this to look ugly.
- By putting
[Settings]
gtk-theme-name = Clearlooks
into /usr/share/themes/Clearlooks/gtk-3.0/settings.ini
you can produce endless loops. Nice!
>From a workaround perspective the most interesting question to me is:
where do I get (default or good looking) CSS files for GTK+ 3.0 Clearlooks.
Best,
Sebastian
