How do I stop my laptop from suspending when closing the lid under lightdm - the power management settings in xfce or gnome 3 does not seem to apply when the window manager is not running.
At the bottom of
sudo vim /usr/share/polkit-1/actions/org.freedesktop.upower.policy
and replace the
no in the
allow_active tags and replace from "yes" to "no" for inactive tags.
- exit your X session, alt+ctrl+f1, and run
sudo /etc/init.d/lightdm restart
Note: I just tested it, and restoring the values back to
yes did not restore the previous functionality... no clue why.
Also, lightdm will still try to sleep, but will be denied. So every time you open the lid, you will get a message box telling the sleep/suspend failed.
this will also prohibit active suspend/sleep
...yet another annoyance that gnome3 brings us
no disable suspend for everything.
I can't find better way to solve this but to switch to another console by pressing CTRL+ALT+F1 and then close the lid.
gksudo gedit /etc/systemd/logind.conf
Worked for me in 16.04.
