Here's what I've found today... If you want to use the OpenGL backend for phonon-based applications (like Minitube) instead of the unaccelerated X11 one, you need to export a "QT_GL_USE_OPENGL1ENGINE=1" env variable.. Otherwise all you can see is a black screen.
This is because Qt4 defaults to OpenGL2, while the phonon backend only supports OpenGL 1.x :( See pobj/qt4-4.8.6/qt-everywhere-opensource-src-4.8.6/src/opengl/qgl.cpp What is for you the right place to put such a note? /usr/ports/x11/qt4/pkg/README-main ? Ciao! David
