dbus puts system to sleep every 30 seconds

[Brock Sides]

After upgrading from 14.10 to 15.04, I found that the system was going to sleep every 30 seconds. This behavior does not manifest once I log into the graphical desktop (Lubuntu), but if I switch over to a virtual console, it manifests again.

A temporary fix has been to make /sys/power/state non-writable.

At first, I believed the problem was with systemd, but the problem continues after switching to upstart.

I believe the problem is in the dbus package, because I see this every 30 seconds in /var/log/syslog, coinciding with the laptop going to sleep:

Status changed to 'Confirmed' because the bug affects multiple users.

[Art Dab (art666)]

I changed systemd for upstart , but the problem persists .

[Brian Murray (brian-murray)]

Are both of you running Lubuntu?

[Brock Sides (philarete)]

I can't speak for Art, but I am.

My case is if after fresh booting up I put my laptop to the sleep mode and then wake it up, it keeps entering the sleep mode again and again every ~30 seconds. I'm running clean ubuntu 15.04.

Attaching the output of "dbus-monitor --system", captured while logged in on a virtual console, for a period of approximately one minute.

I'm having the exact same problem after upgrading from ubuntu-gnome 14.10 on an older HP Pavillion DV1000 laptop. Got a bit too frustrated with it all so I re-installed 14.10 again (so not much use I'm afraid for logs, etc... but maybe the hardware I'm running helps, who knows)...

[Brock Sides (philarete)]

Better solution from a user at Ask Ubuntu: set "HandleLidSwitch=ignore" in /etc/systemd/logind.conf.

http://askubuntu.com/questions/613448/when-i-install-ubuntu-15-04-the-computer-hibernate

This solves the problem completely.

[Brian Murray (brian-murray)]

Brock - ah thanks for that bit of information. This is a duplicate of bug 1438301 then.

[Alessandro Filisetti (alessandro-filisetti)]

Same problem for me, Ubuntu 15.04 Toshiba Satellite U300

[Jalal Albasri (jalal-albasri)]

setting "HandleLidSwitch=ignore" in /etc/systemd/logind.conf did not solve the problem for me.

Razer Blade 14 (2014), Ubuntu 15.04, kernal 4.0.0

i see now

setting "HandleLidSwitch=ignore" in /etc/systemd/logind.conf will my laptop from suspending completely. Not ideal.
