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.
