Keep in mind that setting nvidiafb to totally ignore the EDID (either by not compiling in EDID support or by using e.g. the ignoreedid patch I had proposed) the snow effect is extremely reduced, to the point of being barely perceptible during normal usage (not as clean as X, but still very good). Also, I'm wondering if it might be worth looking at the progress done in nouveau, and the drm stuff they've implemented (or at least the new memory management and maybe some of the 2D stuff). -- Giuseppe "Oblomov" Bilotta - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
