Prevent Sleep on Lid Close in the Fedora 30 Terminal
One the ideas I’ve been kicking around lately is whether or not to leave OpenMediaVault behind in favor of a vanilla Fedora 30 server on my personal NAS. The main reason for going with OpenMediaVault in the first place was that I wanted an easy to configure Samba server. However, as I’ve adopted Linux full-time outside of gaming, Samba is becoming less and less of a requirement and SFTP is filling in the gap — quite nicely.
The testing phase began when I decided to fire up an older laptop and connect up a couple of USB hard disks to act as my storage. The idea is that I would get all the planning, like scripts and cron jobs, figured out before I ever deploy seriously. I knew I’d run into issues, especially since I’m more of a Debian/Ubuntu guy, but even better, I’ll get reacquainted with the way the Red Hat/Fedora community does things.
I plan on keeping track of my experiences with posts when I have to do things out of the ordinary, and maybe a few of the ordinary things, too.
One of those not-ordinary things has already cropped up. The lid, while open, was preventing the screen from turning off. This wasn’t a big deal, I thought, I’ll just close the lid! So, I try it, head back to my ssh session, and realize it’s died. I check the laptop. Asleep. I open the lid, and it springs back to life! ssh can resume! I realize I have to disable suspend on close, but since this was the server edition, which has no GUI, I had to figure out how to do this from the Terminal. Here’s what I did to accomplish that:
- Login and
sudo vi /etc/systemd/logind.conf - Find the line
HandleLidSwitch=ignoreand uncomment it (remove the#at the beginning of the line). If for some reason the line isn’t there, add it to the bottom of the file. Write and quit. - Restart the systemd daemon with
sudo systemctl restart systemd-logind
I had honestly expected it to be a bit more involved, but that was it! Close your lid with confidence!
Thanks man!
Of course! Glad to help!
Thanks heaps. I also thought this would be quite difficult and had been putting off even looking. A quick search on the net came up with your post , clear and concise, and bingo. I can close the screen.
So again, thanks heaps.
I don’t suppose you have investigated laptop wifi ( wlp2s0 in my case ) being “unavailable” when using either nmcli or nmtli ?
eth0 ( eps
So glad you got some use out of it. Was driving me crazy until I figured it out.
If nmcli doesn’t see it, then it’s considered “unmanaged.” Lots of factors here, but this is a good resource to start with.

I’ll consider writing a post about how to let Network Manager handle connections.
