Wohooo... I found it. I took a look at dmesg dmesg | grep -i radeon [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.2.0-24-generic root=UUID=c1466541-e5ae-4cb0-9eea-ae2329bb4fbd ro quiet splash radeon.modeset=0 vt.handoff=7
It seems, that I modified /etc/default/grub long time ago. (I don't know the reasons) With radeon.modeset=1 everything works fine. > glxinfo | grep -i render direct rendering: Yes OpenGL renderer string: Gallium 0.4 on ATI RV530 GL_EXT_vertex_array_bgra, GL_NV_conditional_render, > /usr/lib/nux/unity_support_test -p OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RV530 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/946677 Title: UMS dri support missing for r200 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/946677/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
