How To Quickly Toggle Password Login On/Off And With LightDM

Annoyingduck · 2018-08-30 22:30:42

On my Arch XFCE laptop setup I use LightDM as my display manager. I edit the lightdm.conf to bypass the lightdm login screen and boot right into XFCE without a password. This setup is ideal for me 75% of the time when I'm home, but every now and then I bring my laptop to work and have to manually edit my Lightdm.conf in order to add a password login again. On other distros there is usually a GUI way to do this in their prepackaged setups (basically a GUI to choose whether or not to require a password to login or boot straight to desktop without a password). How can I go about doing this easily on Arch either via GUI or something else that is equally simple? The laptop also has Cinnamon installed alongside XFCE if that helps.

How about an alias to a sed command that modifies lightdm.conf?

I've never done anything like that. Could you list an example that I can maybe start playing around with? I'm guessing this would be a command that I would link to a script?

No, it'd just be a sed command. I could help write it if you actually described what needs to change in the file.

alias lockme='sed -i "..." /path/to/lightdm.conf'

That would be great if you could help with that. Unfortunately at the moment I'm heading out to drink many, many craft beers so I wouldn't be able to post the details until tomorrow, but once I'm able to see again I'll post everything here.

sed is definitely a good way to do this, but if you don't want to write a sed command you could just save copies of lightdm.conf edited both ways (lightdm-autologin, lightdm-manual), and copy the appropriate version to lightdm.conf when you want to change.

Hmm...That just made me think I only have a 3rd grade education due to not figuring that out myself. Pure genius.

I take it there is no GUI way then? Your thought will most definitely be an easy way to do it.

@Trilby, though I'll likely use the dual lightdm.conf method, I would like to learn about sed commands and how they are used. I've actually never heard about sed at all. I'll post my areas that I alter in my lightdm.conf file tomorrow.
