Hi, this is a bit off topic, since it primarily concerns a laptop running OpenSuSe 11.3, but I do need your help and I known there are experts here.
This old laptop has a radeon RV350 (mobility Radeon 9600 M10) graphics card. There is an xf86-video-ati driver installed. Now, when booting with the (default) radeon.modeset=1 the graphics is dead slow (not only for glxgears : 200 frame/s but for my OpenGL application (Impressive), as well). Now, when I replace the option on the kernel command line to radeon.modeset=0 glxgears is much faster ( about 1800 frames/s ) BUT my OpenGL application (python gtk + opengl) now freezes the whole machine - only power on/off can revive it. Hopefully, someone has an idea on what is going wrong here. (The hardware is too old for a recent ATI closed source driver supporting a recent kernel 2.6.34.x) Many thanks for your help which is very much appreciated. Helmut.
