[Tim Cuthbertson <910672@xxxxxxxxxxxxxxxxxx>]

Apologies for not updating this ticket. I've been running fedora for the
last few releases. The fedora bug
(https://bugzilla.redhat.com/show_bug.cgi?id=714334) has been fixed for
a while now.

Given that it originally occurred on both, hopefully it's just an an
upstream fix that ubuntu will get if you've merged xorg-x11-drv-ati,
version 6.14.3. I'm afriad I can't test it out though, as I no longer
run ubuntu - perhaps one of the other affected users can test?

Title:
  [REDWOOD] dell U2410 monitor repeatedly turns itself on and off when
  suspended

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Originally reported in fedora's bugtracker here: https://bugzilla.redhat.com/process_bug.cgi
  But I've since moved to ubuntu. The bug is still present, so I thought I should report it here as well.

  Description of problem:
  Monitor does not standby / turn off, but instead keeps entering and leaving
  standby.

  How reproducible:
  Always.

  
  Steps to Reproduce:
  1. xset dpms force off

  Actual results:
  The monitor goes dark (but not off). A few seconds later, the monitor shows me
  an "entering power save mode" message and then actually turns off the
  backlight. A second or so after that, the monitor backlight is turned on again,
  with a DVI cable symbol in the top left corner as if a cable had just been
  plugged in (my computer is connected to my monitor with DVI, and nothing else
  is plugged into the monitor). Seconds later, it shows the message about
  entering power save mode. This repeats indefinitely.

  This also happens using the normal power saving settings, and leaving my
  computer alone for 5 minutes.

  Expected results:
  Monitor should turn off / enter standby until I wake it
