Suspend issue with my Linux box

A few weeks ago, i completely moved to using systemd on my machine (it runs Arch). And since then i was facing a really weird issue when i closed my laptop lid. My laptop, with Gnome3, suspends itself when i close. And when i open my laptop lid, i was prompted with the familiar gnome-screensaver password dialog, as expected. But right after i could see the password dialog, the system went back to suspend state again. Looking through the system logs, i saw that the suspend was being called twice in succession. And i didn’t have the problem, if I ran pm-suspend from the command-line. It was clear that suspend was being done twice, but i wasn’t sure what was actually triggering it.

After a quick web search and not finding anything useful, i started digging into systemd’s man pages and found the logind.conf(5) man page.  Voila, there it was:


Controls whether logind shall handle the system power and sleep keys and the lid switch to trigger actions such as system power-off or suspend. Can be one ofignorepoweroffreboothaltkexec and hibernate. If ignore logind will never handle these keys. Otherwise the specified action will be taken in the respective event. Only input devices with the power-switch udev tag will be watched for key/lid switch events. HandlePowerKey= defaults to poweroffHandleSuspendKey= andHandleLidSwitch= default to suspendHandleHibernateKey= defaults to hibernate.

The Arch Wiki has a good explanation of the settings in the power management section of the systemd wiki page.

I realised that gnome does its own power management and with systemd running, it does its job of suspended as well. So i had this happening twice. My first instinct was to disable suspend settings in Gnome, but that didn’t seem possible, even with the gnome-tweak-tool installed. So I just put the following lines in my /etc/systemd/logind.conf:


This essentially will make sure that systemd doesn’t handle the system lid and suspend functions.

This is the first issue that i encountered after i moved to using systemd. (A non-issue actually). I am very happy with how systemd works. I should admit i was quite skeptical before i started using it, but now I’m very used to the whole idea. And whats more, i do notice the faster boot and shutdown times. I haven’t actually measured it, but I’m quite sure that if i did, i would notice a difference. But, thats for later!
