Troy, Though I didn't go over your xorg.conf file too closely, I don't think that's your problem. The problem is in the Xorg7 Radeon driver. There is an update posted at http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/5/i386/xorg-x11-drv-ati-6.5.8.0-1.i386.rpm. I think you can install it by typing something like: sudo yum --enablerepo=updates-testing update xorg-x11-drv-ati BEWARE! On some ATI boards, this update will lock up your machine randomly. There's already a bug filed on this that hasn't seen any activity for a while: https://bugs.freedesktop.org/show_bug.cgi?id=5781 This is what I'm experiencing. A week ago, I did a complete checkout and build to see if CVS HEAD fixed this problem. I found that it made no difference on my T30. Good luck. John
