Comment 27 for bug 408065

Cairo-Dock with OpenGL works without any problem with nVidia and Intel graphic cards (only on Karmic for these Intel cards).

One Cairo-Dock dev have an old laptop with a radeon graphic card. He has tested with the xorg-edgers ppa and "radeon.modeset=1" option but his system became unstable due to Xorg.

After a 'dpkg-reconfigure' for Xorg packages, he has tested Cairo-Dock but there is still a black background and "glxinfo | grep nGL" gives "OpenGL version string: 2.1 Mesa 7.5"

@mac_v : Can you confirm the version of Mesa ?

PS : I quote Phoronix : "It happened on Friday night, but the Linux 2.6.31-rc7 kernel is now available. The seventh release candidate for the Linux 2.6.31 kernel brings a variety of small fixes, including a Radeon DRM update. The Linux 2.6.31-rc7 release announcement can be read at LKML.org.

The Linux 2.6.31 kernel should be released in early September and it brings staging support for ATI kernel mode-setting support, the mainlining of the TTM memory manager, various graphics DRM driver improvements to ATI and Intel in particular, improvements to different file-systems, new drivers, and much more."
