Autologin "normally" without a password and execute xlock.With using a password?
That's the point of a login manager.
yeah, a misnomer that somehow stuck. I'm guessing that this is because the greeter actually launches Xorg after the user logs in. Not the easiest-to-understand logic, but that's how Xorg actually works.Also, why on earth are these called "display manager"? As I understand them, they are more of a login manager.

Quite useful for testing purposes and/or helping people using another desktop than you.Regarding switching to an alternative desktop: Why would one use more than one desktop?
Which types of interfaces does a login manager actually use? Surely it can't use X for rendering. Does it use the kernel framebuffer (at least that is a thing in Linux)? I take it that keyboard & mouse inputs can be grabbed through devd/evdev?yeah, a misnomer that somehow stuck.

I'm not doubting that it works, I'd just like to understand how it works
If you can just point me to some documentation …

XDM specifically does launch an Xorg session (preferably not as root). The user logs in and then the login manager transfers access / ownership of the UNIX socket files (i.e in /tmp/) to the user as well as copying over the Xauth / Xauthority related files.Which types of interfaces does a login manager actually use? Surely it can't use X for rendering.
Would love to get a link to those devices and/or some more technical informationI ship FreeBSD systems for controlling electrochemical laboratory devices (potentiostats/galvanostats) with gdm/GNOME3.

Crontab with autologin??? that's not making much sense. I think people really should be in the habit of typing in the password. This really amounts to treating your computer like a grocery store that has automatic sliding doors installed at the front entrance, AND cash registers that don't have locks.Yes, quite possible. Have run in crontab for an ordinary user@reboot startxfce
. Works a treat.
Ultimately unless you have an encrypted hard drive, typing in your password for "security" at a local machine is little bit of an illusion. It is very easy to bypass and access files via a boot disk.I think people really should be in the habit of typing in the password.

Yeah, but you'd need physical access to the hard drive.Ultimately unless you have an encrypted hard drive, typing in your password for "security" at a local machine is little bit of an illusion. It is very easy to bypass and access files via a boot disk.
If you have your BIOS locked, most machines can just be reset by taking the battery out for 30 seconds.
Interesting info, but I think it's veering off-topic. I fail to see the connection between a couple topics:https://cyclaero.com/de/simulations/Cyclaero Ltda.

I set up a simulation (a device and a dummy cell) with my software controller on an AWS server in Frankfurt:
Username: test
Password: cydaq
There is another simulation running here in Brazil (same username and password):
However, from Switzerland the server in Frankfurt must be more responsive.
I am a German living in Brazil and I am in cooperation with the traditional Potentiostat developer and supplier Bank Elektronik in Germany. I am responsible for the controller including the operating system (FreeBSD) and the measurement daemon (CyDAQec) and the analysis software (CVA). The controller can be used together with various systems from Bank. It can be used completely headless as well, like the simulations do suggest. The analysis software runs on macOS and Windows.
Most probably I will resettle to Germany in the foreseeable future.
