Title:
Network broken after resume
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After a first suspend, it takes ~60 seconds for one to be able to login. We
use Dell Optiplex 7010 machines in our student lab. Because of the LDAP
authentication, networking is required for authentication. So, restarting
network-manager is not an option. I have tried numerous things, such as
creating a file /etc/pm/config.d/network-resume with the content:
"SUSPEND_MODULE="e1000e"
However, this seems to break the suspend functionality. When manually
entering "suspend" it goes directly to the lock screen.
I also tried creating a file /etc/pm/sleep.d/network-resume with:
#!/bin/sh
case ${1} in
resume|thaw)
nmcli nm sleep false
;;
esac
Once resumed networking is disabled, and thus I cannot log in.
* creating a file in /etc/pm/sleep.d with
#!/bin/sh
case "${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.
