Hi, Adam.

The question is the overall video performance. I have a Dell mini 10, and it seems to me that something just stopped working since Fedora 13 or 14.

I filed a bug about this in January:

Later, a guy from my LoCo gave me a configuration snippet taken from Ubuntu forums that solved my problem and turned it back to how it was on Fedora 12.

~/.driconf

    <driconf>
    <device screen="0" driver="dri2">
    <application name="Default">
    <option name="vblank_mode" value="0" />
    </application>
    </device>
    <device screen="0" driver="i915">
    <application name="Default">
    <option name="force_s3tc_enable" value="false" />
    <option name="no_rast" value="false" />
    <option name="always_flush_cache" value="false" />
    <option name="early_z" value="false" />
    <option name="stub_occlusion_query" value="false" />
    <option name="always_flush_batch" value="false" />
    <option name="bo_reuse" value="1" />
    <option name="texture_tiling" value="true" />
    <option name="vblank_mode" value="0" />
    <option name="allow_large_textures" value="2" />
    <option name="fragment_shader" value="false" />
    </application>
    </device>
    </driconf>

I have a question: can we get this to work out of the box? I'm willing to provide any logs if needed. You may see the video performance is different like heaven and hell.
