Title:
  Unrecoverable crash when suspending from inside a virtual machine

Status in “xserver-xorg-video-vmware” package in Ubuntu:
  Fix Released
Status in “xserver-xorg-video-vmware” source package in Precise:
  Fix Committed
Status in “xserver-xorg-video-vmware” source package in Quantal:
  Fix Released

Bug description:
  [Impact]
  Low to medium, when using the virtual machines I believe it would be more common to suspend the VM from the host instead of leaving the machine running in S3, but it is 100% reproducible and requires a hard power off to fix if an S3 is triggered from inside the VM so loss of data can occur.

  [Development Fix]
  Installing a modprobe.d conf file containing "options vmwgfx enable_fbdev=1"

  [Stable Fix]
  Backport the above fix to 12.04

  [Test Case]
  1) Install the VMware Player, Fusion, or Workstation products
  2) Install Ubuntu 12.04 in a new virtual machine
  3) Suspend from inside of the virtual machine, not from the host.

  If the display recovers normally on mouse movement it is fixed. If it
  goes black and never recovers without a hard power off it is broken.

  [Regression Potential]
  Low, this fix only adds a modprobe.d conf file enabling the enable_fbdev module option by default. It only affects VMware platforms and has been QAed by them to be sure its the proper fix. xserver-xorg-video-vmware is also used for KVM, but the vmwgfx KMS driver in the kernel is not so the option will have no effect.


  Original Report:
  When suspending from inside the virtual machine (not from vmware player/fusion/workstation) I get a crash in dmesg and the display doesn't come back.
