Missing monitor information in gnome-display-properties or xrandr

Solution Verified - Updated -

Issue

  • gnome-display-properties identifies a monitor as "Unknown" instead of providing vendor and model information.
  • xrandr -q --verbose output does not contain EDID data (but EDID data may be present in /var/log/Xorg.0.log).

Environment

  • Red Hat Enterprise Linux 6 (RHEL6)
