** Description changed:

  After some user switches using either the switch user appet or "switch
  from..." or on the login screen, my computer hangs.
  
  Note that this does not happen every time I switch users, only after
  about every 3rd switch. The only resolution I found for the freeze is a
  cold restart.
  
  My hardware is a Lenovo W500 laptop, with 2 graphic adapters. I disabled the ATI adapter in the BIOS, ubuntu thus only sees the Intel adapter. lspci reports it as: 
  00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
  
  Here is the adapter info from Xorg.log:
  (--) PCI:*(0:0:2:0) 8086:2a42:17aa:2114 Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller rev 7, Mem @ 0xf4400000/4194304, 0xd0000000/268435456, I/O @ 0x00001800/8
  (--) PCI: (0:0:2:1) 8086:2a43:17aa:2114 Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller rev 7, Mem @ 0xf4200000/1048576
  
  
  I found the follwing report in my Xorg.log, making me strongly believe
  the graphics adapter is the problem here.
  
  (II) intel(0): Modeline "1920x1200"x0.0  125.66  1920 1950 2030 2060  1200 1202 1206 1220 -hsync -vsync (61.0 kHz)
  [mi] EQ overflowing. The server is probably stuck in an infinite loop.
