Attach your X server log and config file as individual uncompressed file
attachments using the link below. After that, please try the following option
in xorg.conf as a diagnostic test:
Option "PciOSConfig" "1"
In what section of xorg.conf do I put this option? The available sections are:
"ServerLayout", "Files", "Module", "InputDevice", "Monitor", "Device", "Screen"

/var/log/Xorg.0.log after rebooting with Option "PciOSConfig" "1" in xorg.conf
Ran "yum update" then rebooted machine. Retrieved Xorg.0.log (see attachment
Xorg.0.log-v1). Added Option "PciOSConfig" "1" to xorg.conf, rebooted machine,
and retrieved Xorg.0.log again (see attachment Xorg.0.log-v2)
Can you paste the relevant section of "lspci -v" ?
