I have a X3100 Graphics Card and I am using Ubuntu 9.04. The 2D (and 3D) rendering is very slow. Some OpenGL (in this case a Ogre 3D game) programs have very ugly rendering errors like you see on the attached picture.
I searched for drivers and found out that all needed video drivers are installed automatically. So, I think it's a question of configuration.
Can you help me?
Thanks in advance
