Angry Cannot suspend laptop in Ubuntu 14.04.3

I installed the DisplayLink driver in mid-September. It worked intermittently for a few weeks and then not all.

Anyway, two weeks ago my laptop stopped being able to suspend. Each time I clicked suspend, the laptop would immediately wake/resume.

I removed /etc/pm/sleep.d/displaylink.sh and now I can suspend!

To raise it with the engineering team I need more information. Could you please gather log information from your system? In particular, it would be helpful if you restored /etc/pm/sleep.d/displaylink.sh (may require reinstall if you've completely removed it) then reproduce the issue and follow the instructions from this article:

Thank you,

Default my workaround and fix

I had a similar issue, failure to suspend. This happened after I had a problem with DisplayLinkManager occasionally going crazy and eating half my CPUs, even if no display was installed. That's another problem, though, which I am owrking around by setting the service to manual launch. When I did that, I can no longer suspend, because of how the pm suspend script is written. I added this stanza at the top:

if [ ! -e /usr/lib/displaylink/PmMessagesPort_out ]; then
exit 0

So the script does not fail if the manager service isn't running.


P.S. the informative log for this case is /var/log/pm-suspend.log
search from the bottom for Error
