Title:
  Various instabilities after resuming from standby

Status in xorg package in Ubuntu:
  Expired

Bug description:
  None of these problems are readily reproducible, I'm having a roughly
  30:70 chance of a successful standby. Things that I have seen happen:

  1) Click on Whisker menu -> Logoff ("Abmelden") button ->
  Logoff/Restart/Reboot/Standby dialog (no Hibernate option, I think
  it's blacklisted for my machine) -> Click on "Shutdown" -> no
  shutdown, I get the login screen.

  2) Trying to go to standby from the Logoff button in the login screen
  after seeing (1) -> monitor switches off, then on, login screen again.

  3) After (2), close the lid, open it, standby procedure from login
  screen -> works. Sometimes.

  4) After (2), remove machine from docking station, standby procedure
  from login screen -> works. Sometimes.

  5) Machine is in standby, I press the power button, I get some text
  mode messages, monitor flashes and shows graphic content (mostly a
  mouse cursor on some background, too fast to properly see), then the
  screen goes dark. Ctrl-Alt-F1 works, Ctrl-Alt-F7 simply makes the
  screen dark again (both the builtin laptop screen and one of the
  external, connected-through-docking-station screens).

  6) The effects from (5) can also happen right after cold booting the
  machine.

  7) I *think* on a few occasions, I tried to shutdown the machine and
  nothing happened at all.

  8) On some rarer occasions, nothing would happen after the shutdown
  command, and trying to issue another shutdown resulted in a message
  amounting to "can't do another action while the previous action is in
  progress"; I remember pstree reported some hung process that was
  connected to shutdown, and I couldn't kill it (not even kill -9). I
  cannot reproduce this, and I didn't take notes so I can't be more
  specific.

  I have no idea which of these effects are related to a common cause and which are independent.
  I have been unable to find out anything given that no individual phenomenon is reproducible with any reliability.
  I hope the attached debug info will help, but I fully expect this to require much more diagnosis.

  Hardware:
  - Docking station PR02X
  - Two 2560x1440 Dell U2515H monitors, one on each video output of the docking station
  - nVidia Quadro 2000M, using the proprietary driver (Nouveau cannot drive two 2560x1440 screens)
