From dmesg after the crash. Xorg[12774] general protection rip:2b3daaff218b rsp:7fff01440950 error:0 Anyone experiencing X11 crashes? I have an amd 6400+ centos 5.1 x86_64. This typically happens when I VNC in from home into my machine at work. My machine has nvidia card and I do run the binary drivers. However, I switched out for a short time and ran the nv driver and it happens there also. Any ideas? Anyone else see this? Anyone else using vnc? I do load in xorg.conf the vnc module. Jerry
