Title:
  excessive swapping on resume renders laptop useless 20% of the time

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  After resuming from suspend, on average one in five times excessive
  swapping starts. This often continues for several minutes, but
  sometimes even for ten minutes or more (I'm not always patient enough
  to sit it out). During this phase, it is not possible to log into the
  screenlock, because the password dialog is not (yet) showing. I can
  log in to the text console, but repsonse is slow and sluggish. atop
  registers massive disk IO (duh) and equally massive memory allocation
  and de-allocation. Often, I see processes like firefox, thunderbird,
  Xorg, ooffice (and others) deallocating 100's of MBs, to reallocate
  them shortly after.

  WORKAROUND: Run the following in a terminal:
  gksudo gedit /etc/sysctl.conf

  Add to the end of the file:
  vm.swappiness=10

  Save and close. Then reboot your computer, or execute:
  echo 10 | sudo dd of=/proc/sys/vm/swappiness
