Title:
  Lenovo IBM R61i: Resume from suspend freezes xorg desktop

Status in “linux” package in Ubuntu:
  Confirmed
Status in “pm-utils” package in Ubuntu:
  New

Bug description:
  Each time when I suspend my Lenovo IBM R61i laptop to RAM and was
  trying to resume, the Xorg/desktop freezes, I can do nothing but hit
  the power botton to restart my system.

  Steps to reproduce:
  1. Click "Suspend" located within the right-top dropdown of the unity desktop;
  2. After the computer completly suspended to RAM after a few seconds, hit the power botton on the keyboard to resume from suspend.

  Current behaviour:
  After about 15 seconds' freeze I can input password in the lock-screen window, but when hit ENTER xorg freezes. I can do nothing but reset the power button. Ctrl+Alt+F1~F12 do not show up the terminal.

  This bug behaviour do not happen in Fedora 20, which I installed in
  the same laptop.

  $ uname -a
  Linux suokunlong-ThinkPad-R61 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:31:42 UTC 2014 i686 i686 i686 GNU/Linux

  $ lspci
  ......

  I was able to copy the attached log files with Fedora (which I
  installed with Ubuntu on the same laptop) after I reproduce the above
  steps.

  If any other information is need, I can provide.
