Hmm, maybe it still uses GL via Qt, or Qt uses GL internally, or creates a GLX context even though it doesn't. I don't suppose switching Myth to use GL directly helps? :} Unless you need GL otherwise with this server, you could work around it by not loading the "glx" module in xorg.conf. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer
