The first time it takes 60 seconds to log in, and it seems that
networking is broken during that time.

Subsequent logins take only three seconds, and also see almost no
downtime in networking.

Title:
  Network broken after resume

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  We use Dell Optiplex 7010 machines in our student lab. These machines
  are capable of suspending and resuming, so that we don't waste power
  during the night. In our lab we also use LDAP authentication for the
  students. The problem is that networking is disabled once the machine
  is resumed after a suspend. Because of the LDAP authentication,
  networking is required for authentication, thus we cannot login to the
  machine after a suspend. A "work-around" to restart network-manager is
  therefor not an option.

  I have tried numerous things, 
  * creating a file /etc/pm/config.d/network-resume with the content "SUSPEND_MODULE="e1000e"

  Outcome: This seems to break the suspend functionality. When manually
  entering "suspend" it goes directly to the lock screen. The networking
  is still disabled, so I cannot log in.

  * creating a file /etc/pm/sleep.d/network-resume with

   #!/bin/sh

  case ${1} in
  	resume|thaw)
  	nmcli nm sleep false
  		;;
  esac

  Outcome: Manually suspending works, resume only works when pressing
  the power button. Once resumed the networking is still disabled, and
  thus I cannot log in.

  
  * creating a file in /etc/pm/sleep.d with

  #!/bin/sh

  case "${1}" in
          resume|thaw)
          restart network-manager
                  ;;
  esac

  Outcome: Manually suspending works, resume only works when pressing the power button. Once resumed the networking is still disabled, and thus I cannot log in. After about a full minute networking is restored and I can log in.
