OpenGL GLX context is not using direct rendering, which may cause performance problems.
I'm using Ubuntu 13.04 64-bit on my system and this error occured today. I tested the nvidia x-org file and the nvidia config also says that openGL works fine.
I followed the troubleshooting guide but nothing seemed to work. I also added the username to the video group but this didn't work too. It seems that this is a problem with my graphic drivers and steam which cannot access to the 32 bit libraries.
How can i fix this?
I'm using the Nvidia 304.88 driver as this was the only one who gave me the message that openGL rendering is enabled. The newest (310 and 313) didn't give me any openGL enabled messages.
