You need Jesse's kernel patches which make pageflipping work: http://lists.freedesktop.org/archives/intel-gfx/2011-June/011014.html Without those, most fullscreen apps will GPU hang. As far as I know, those patches fix the issue. Thanks. Using Jesse's kernel patches, xscreensaver can run well in Ivy Bridge and Sandy Bridge.
