Ubuntu Unity runs OK but I can't use the Suspend or Hibernate features at all?
There is a space or should be in between whe snyc; and the sudo in that line. LQ pulls out some spaces, so be careful.
In that line, 'mem' = memory which is suspend
disk = hibernate. Sometimes this is called through HAL by window managers, and that bit can fall over. In the terminal, you get to see errors.
