I've confirmed this is the problem, the intel drivers need AGP for 2D code paths, the DRM then acquires the bridge for 3D code paths... this is standard and we can't change it now as it would mean changing existing userspaces.. I'm not sure how to tackle it.. Brice's patch may work in all cases but I want to check it on a few configurations .. Dave, now running (FC3+Xorg CVS and Debian Sarge and switching between i865/radeon/mga cards trying to track these bugs down...) - 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/
