I am now testing Karmic Alpha 1 and the problem is still here. UXA works on kernel 2.6.30-5-generic but not 2.6.30-5-server which are available on Karmic.
This bug is important because as support for EXA will be dropped we will all be using UXA which means everyone who uses -server kernels or has 64GB mem option selected will be unable to do so. ** Bug watch added: freedesktop.org Bugzilla #17993 https://bugs.freedesktop.org/show_bug.cgi?id=17993 ** Also affects: xserver-xorg-video-intel via https://bugs.freedesktop.org/show_bug.cgi?id=17993 Importance: Unknown Status: Unknown ** Summary changed: - Kernel High Memory Support <64GB> incompatible with intel video UXA + Kernel High Memory Support 64GB [PAE] incompatible with intel video UXA ** Description changed: - In Jaunty with Intel GM965 video, trying to add Option "AccelMethod" - "UXA" to /etc/X11/xorg.conf results in a system freeze with a black - screen when X starts if you use the -server kernel.
