Comment 24 for bug 34659

The Xv texture adaptor doesn't have color controls on GeForce 6 and 7 series GPUs. For GPUs that also have an overlay adaptor, that has color controls but is disabled when the Composite extension is enabled, which is by default. If there's a bug here, it's that Totem presents the color control UI elements when the underlying hardware doesn't support them. It should be querying the adaptor to see if it supports the XV_HUE, XV_BRIGHTNESS, etc. attributes. You can use xvinfo to get a list of the available adaptors and their supported attributes.
