The only part that runs in ring 0 is the video driver. The GUI itself runs in userspace. In Linux the graphics driver runs in userspace, but even that can freeze a machine because it requires direct hardware access. My Radeon HD 2400 PRO driver will cause an immediate lockup if I run X, then quit X, then start X again. So the ring-0 stuff is a bit of a red herring. -- rgds Stephen _______________________________________________ CentOS mailing list [email protected] http://lists.centos.org/mailman/listinfo/centos
