Gtk system wide themes should be in /usr/share/themes, if you followed the book ...and iirc
. If you compiled and installed to default location, check /usr/local/share.
Here's how I do it,
Code:
>ls -l /usr/share/themes/Default/
drwxr-xr-x 3 1000 1000 96 Mar 2 07:07 Black-Marble
drwxr-xr-x 3 1002 1002 72 Apr 26 19:42 Darkjungle
drwxr-xr-x 4 root root 152 Feb 16 06:19 PrettyBlueish
drwxr-xr-x 3 1000 1000 96 Oct 16 2002 fishpie
lrwxrwxrwx 1 root root 14 Apr 30 18:27 gtk -> Darkjungle/gtk
lrwxrwxrwx 1 root root 15 Apr 30 18:37 gtk-2.0 -> fishpie/gtk-2.0
drwxr-xr-x 2 root root 72 Mar 27 09:06 gtk-2.0-key
drwxr-xr-x 4 root root 96 Apr 26 19:15 oem
...oem is where I've backed up the default theme, the rest is themes I downloaded and I use symlinks.
But be carefull, some apps will have their own gtkrc files in their dot dir. in the user accounts, I just link the to the gtkrc directly in those cases
Code:
>ls -l ~/.gimp-1.2/gtkrc*
lrwxrwxrwx 1 root root 54 Apr 30 18:35 /root/.gimp-1.2/gtkrc -> ../../usr/share/themes/Default/PrettyBlueish/gtk/gtkrc
-rw-r--r-- 1 root root 198 Mar 26 14:49 /root/.gimp-1.2/gtkrc.oem
