Title:
  30 sec Xorg freeze - ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument
  #4 type mismatch - Found [Buffer], ACPI requires [Package]
  (20131115/nsarguments-95)

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  XOrg freezes for about 30 seconds and this warning is printed in the
  syslog:

  kernel: [  752.250482] ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20131115/nsarguments-95)
  kernel: [  752.250740] ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20131115/nsarguments-95)

  However, the console still works while X is frozen.

  This is a Dell XPS L702X with optimus graphics.

  The freeze appears to occur randomly. 
  Using nautilus, gedit or other gtk3-programs seems to cause it happen more frequently.  Eclipse and Chromium that uses gtk2 does not seem to trigger the bug.

  There are two similar bugs:
