I upgraded my OS from Lubuntu 13.10 to Lubuntu 14.04 a few days ago, and now my screen locks when the lid is closed, while I want nothing to happen when lid is closed.

I have already set the right option in the Xfce power manager ("When laptop lid is closed: Nothing") and, as of https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1307545 and Closing laptop lid suspends Lubuntu, since upgrade , I tried editing /etc/systemd/logind.conf; but when I close the lid, the screen still locks and asks for a password. Note that this doesn't happen every time I close the screen; sometimes it stay closed for a few minutes and can be reopened without having been locked, and sometimes it locks as soon as I close the lid.

For reference, here's the content of my /etc/systemd/logind.conf:

LidSwitchIgnoreInhibited=no

Is there's something wrong with what I'm doing? What can I do to be able to close the lid without anything happening?

EDIT: Possible pointers would be about what exactly happens when I close my lid; I tried investigating in that direction, but I don't know where to start. If a script or something is called on lid closing, I might even be content with modifying it to do nothing.

You're on the right track with logind.conf, but you only need to change this line from the default configuration:

HandleLidSwitch=ignore

(i.e. you don't need LidSwitchIgnoreInhibited=no).

In addition, you need to configure xfce4-power-manager to handle the lid switch. I found that the reliable way was to Quit it from the power manager icon menu before configuring it with

$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s true

You'll then need to restart (unless there's another way to get logind to pick up its configuration, in which case I'd love to hear it!).

After this, the lid switch should operate according to the settings in the power manager.

I found this solution thanks to a comment on a bug linked by a helpful person in #xubuntu.

Note that this breaks screen locking on suspend.

    as for getting logind to read its config: $ restart systemd-logind

  • This is the right answer. I can't believe there is no other way to accomplish this in Xubuntu.

  • Since 15.04, sudo service systemd-logind restart to reload logind configuration. See askubuntu.com/a/372616

  • Do NOT modify /etc/systemd/logind.conf directly, as it will be eventually overwritten by an update (happened to me the other day). Create a *.conf file under /etc/systemd/logind.conf.d instead (see man /etc/systemd/logind.conf).

I solved uninstalling xfce4-power-manager and rebooting. It could work because systemd and xfce4-power-manager are in conflict

  • It works, but I'd prefer to keep xfce4-power-manager... I'm going to see if I can look in the matter a little further, otherwise yours is the best solution as far as I can see

sudo /etc/UPower/UPower.conf

change: ignorelid=false to ignorelid=true

ctrl o (save/write) crlt W (exit

no need for reboot-should work right away.

Not sure what all that other stuff is...complicated for sure...

Cheers
