After being on vacation and having stress at work I wanted to test on
oneiric alpha. Problem is currently more serious, so I can't even start
testing this.

I already have a Natty test machine - but there is no VirtualBox on it
yet - will do that and re-test on natty.

Title:
  Gnome desktop freeze / hangup after calling xrandr

Status in “gdm” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: gdm

  My report is somehow related to Bug #617421 however, effect more
  critical and including data loss.

  From time to time it happens that the screen shortly flickers and a
  second monitor gets detected (by mistake).

  It happens even without touching mouse or keyboard - this time I was
  taking notes on paper.

  The screen/monitor that gets detected can be TV1 when I am working on
  my laptop only or LVDS1 when I am in docking station with external
  monitor attached and laptop lid closed (LVDS1 is the laptop-builtin-
  monitor/screen).

  When I then call xrandr for example using:
  xrandr --output HDMI1 --mode 1680x1050 --rate 60 --primary --output LVDS1 --off --output TV1 --off --output VGA1 --off --output HDMI2 --off --output DP1 --off --output DP1 --off --output DP2 --off --output DP3 --off 

  (in this case to switch to the external monitor only), the Gnome
  desktop completely freezes / locks up. Switching to a text console
  with CTRL+ALT+F1 for example, does not work either. Mouse pointer does
  not move - nothing. I have to switch off the laptop and restart.

  Unfortunately this is not reproducable - it does not occur always.
  Often the xrandr call is successful without freezing everything.

  The only thing I can tell so far is that I am pretty sure, that
  always, when it happens the VirtualBox is started with at least one
  virtual machine being up (with a Windows guest). I also tried
  disabling all acceleration features within VirtualBox (2D and 3D),
  remote display disabled - and I gave 63 MB of video memory which
  should be enough. Monitor count is set to 1.
