You need to add a seperate dri2 device to .drirc for vblank_mode to
work there, driconf doesn't work right


    <device screen="0" driver="dri2">
        <application name="Default">
            <option name="vblank_mode" value="0" />
        </application>
    </device>

my full ~/.drirc for example


<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="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="early_z" value="false" />
            <option name="allow_large_textures" value="2" />
            <option name="fragment_shader" value="false" />
        </application>
    </device>
</driconf>
