  Intel graphics fails when bringing monitor out of sleep

Bug description:
  I have a HP LP2475w monitor. Sometimes when the system has put it to
  sleep, it fails in bringing it back up again. The screen remains
  blank. Even changing virtual terminals with ctrl+alt+f1 does not work.
  Ssh'ing in and running 'sudo service lightdm restart' makes it come
  back up again.

  This error shows up in dmesg:

  [18380.721810] [drm:drm_edid_block_valid] *ERROR* EDID checksum is
  invalid, remainder is 125

  This monitor worked flawlessly on my previous computer which had
  NVidia + the binary driver.
