Openbox+transparent

никак. хочеш перделок - лезь обратно на флукс.

Подскажи, как ты его настраивал?
Где у него конфиги?

В /etc/xdg/openbox/ лежат rc.xml menu.xml.
Но как изменить тему и шрифты?

есть такая прога оф.сайте опенкфг она темы прикручивает + шрифты

Прога называется правильно Obconf. Шрифты они не прикручивает. Она позволяет выбрать тему, из имеющихся установленных.
Автору вопроса про шрифты - идти читать

Themes

First off, the theme format is not backwards compatible with Openbox2/Blackbox/Fluxbox themes. The themeupdate.py script included in the Openbox distribution can be used to aid in porting Openbox2/Blackbox/Fluxbox themes over.
Paths

Themes are searched for in the data directories specified in the base-dir spec mentioned in the File locations section. In addition to these paths, Openbox also looks in $HOME/.themes/ for backwards compatibility with existing applications. This means, by default, the following directories will be searched in order: $HOME/.themes/, $HOME/.local/share/themes/, $PREFIX/share/themes/. This means that Openbox themes can now be bundled with other themes (such as GTK+ themes).
Structure

Each theme is self-contained within its own directory. The theme file itself is a file named themerc inside the theme's openbox-3 directory. So for a theme named "Foo", its directory layout might look like this:

Foo/openbox-3/themerc
Foo/openbox-3/max.xbm
Foo/openbox-3/close.xbm
