After uninstalling the nvidia drivers, my system was borked: Unity
wouldn't start (complained about not being able to find a valid screen
layout). After some messing with that, couldn't log in (screen freezes
after supplying credentials). This has unfortunately taken some time to
fix.

I'm currently on 3.13.0-34-generic, and suspend seems to work,
miraculously. It didn't come back up, however.

Title:
  [Lenovo ThinkPad Edge S430] Suspend fails

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When suspending the machine (clicking cogwheel in upper right corner):
  * the computer starts doing what it does before suspending
  * the screen goes black (which is the way it used to be)
  * some message about failure is displayed briefly, and i get the login screen.

  The attached (i believe) syslog shows the error, it's:
