Sounds a bit like 556261. Can you turn off acpid and see if this still happens? Cheers, Julien
Yes! That's it!For completeness, during testing the fix I also noticed that docking/undocking also triggered the problem.
Like 556261, I am using acpid 1.0.10-3. I followed the advise of the upstream in 556261 which was to remove a few files, like /etc/acpi/events/videobtn (and a few more). http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=556261#33
Upon doing that and restarting acpid the flickering stopped and now my system happily will go through a suspend/resume and dock/undock reliably.
Thanks! :) -Jeff
