            exec_prefix:         ${prefix}
            libdir:              ${exec_prefix}/lib
            includedir:          ${prefix}/include
    
            Kernel modesetting:  yes
    That should do the trick and I did that right from the beginning. What strikes me as odd is the fact that I know my hardware should do it. Back in April when jglisse released his first repo and compiling instruction, I had it working, albeit rather unstable.

    Addendum: The kernel I am using is an experimental kernel:

    http://wiki.mandriva.com/en/Docs/How...els#kernel-tmb
    2.6.31.6-tmb-laptop-7mdv

    However, maybe it's this:

    Code:
    grep -i kms /boot/config-2.6.31.6-tmb-laptop-7mdv
    CONFIG_DRM_KMS_HELPER=m
    CONFIG_DRM_I915_KMS=y
    CONFIG_DRM_NOUVEAU_KMS=y
    # CONFIG_DRM_RADEON_KMS is not set
    I created a new initrd with radeon preoloaded and that probably should be just as good, because KMS actually worked as can be seen in the HiRes Framebuffer console and fast switching between X and console.

    Check your dmesg to see if you are actually using kms.
