In addition to my last email the Xorg-X11 release that worked the best was Xorg-X11 6.8.1-4. With the addition of the line in xorg.config (as in the previous email). Everything worked properly. I found out it was Xorg that was killing X not the kernel. Right now I am running kernel 2.6.8-1.624 and everything is ok, openGL is a little slow but that is about it. Mike
