quote: Getting back on track with fglrx 8.27.10... First and foremost, ATI has beat NVIDIA to supporting X.Org v7.1 in their proprietary drivers. X.Org v7.1 is supported in the fglrx 8.27.10 drivers except for the GLX_EXT_texture_from_pixmap extension. This OpenGL extension allows a color buffer to be used for both rendering and texturing, and is needed for AIGLX. We would not expect to see this extension supported by fglrx for at least a couple more months. X11R7.2 is already planned for release later this year. For reference, NVIDIA likely will not be delivering their 1.0-9XXX drivers with X11R7.1 support until August or September of this year. NVIDIA's drivers are expected, however, to support GLX_EXT_texture_from_pixmap. Another note about the X.Org 7.1 support is that X-Video with X1k products will not work, but it should be corrected in future releases.
