Title:
  1002:9591 [Lenovo ThinkPad T500] External monitor on display port has
  no sync with radeon driver

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When I turn on the external monitor, it displays an error message:
  "The current input timing is not supported by the monitor display.
  Please change your input timing to 1920x1080@60Hz or any other monitor listed timing as per the monitor specifications."

  WORKAROUND: Installing fglrx-legacy 8.97.100.7 on Ubuntu 13.04 solves
  the problem.

  The GNOME display settings dialog shows exactly this recommended setting as current.
  I even tried to set it up using xrand with:
  $ xrandr --output DisplayPort-0 --auto -s 24/1920x1080 -r 60

  $ xrandr -q
