Accelerated Indirect GLX (AIGLX) has been added to FC5. Since I'm using an NVIDIA card w/o native drivers could this be the problem? http://rpm.livna.org/ doesn't have the lastest drivers "A note for users of ati-fglrx and nvidia-glx: Due to a bug in the FC5 release kernel users of non-GPLed kernel modules will have to wait for an errata kernel; that should happen soon. " Hopefully in a few days -- the kernel will be fixed and then the drivers will be added and I can test it to see if this could be the source of the problem. -- This is an email sent via the webforum on http://fcp.homelinux.org http://fcp.homelinux.org/modules/newbb/viewtopic.php?post_id=73077&topic_id=17722&forum=10#forumpost73077
