Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
  Freeze when resuming from automatic suspension to RAM

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  Automatic suspension causes the system to freeze on resume. This
  doesn't happen if I suspend it manually by opening the system menu and
  pressing the suspend button. Suspension works flawlessly when it is
  triggered manually.

  When the system resumes from automatic suspension, the lock screen is
  visible but does not respond. It's frozen. A notification says
  something like "system will suspend shortly due to inactivity". It
  never goes away.

  The keyboard responds during this (at least for a while). The CAPS
  LOCK LED turns on and off as I press it (with no delay). Sometimes I
  can even switch to another TTY and kill the X server, which is why I'm
  reporting it against gnome-shell. When switching TTY is impossible, I
  use the "REISUB" combination to shut down. Either way, I always lose
  the running session.

  This is reproducible about 60% of the time. Eventually I ended up
  disabling it and relying only on manual suspension.
