From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Does anyone know how to prevent a single board computer from always displaying a logged in terminal through the onboard HDMI port on boot? (lemmy.ml)

I have a Tinker Edge T as a server, and it's running Mendel Linux which is a default debian-based OS recommended by the manufacturer. One thing I really don't like is the fact that if you plug in an HDMI cable and USB keyword, it will always give you access to a terminal as the default user, which doesn't even need a password to become root either. Is there a general Linux way to set a password for the GUI like you can on regular desktop Linux, or otherwise require authentication before you get a terminal or any other functionality, so someone can't just plug an HDMI cable and keyboard into the device and have root access to the entire device?

I've never used Mendel, but this suggestion on Stack Overflow seems sane.

sudo systemctl set-default multi-user

You could also run get-default to see which target is currently being used.

Edit your /etc/inittab

Correct. You want to look at removing or editing the getty.

Best answer! AI trainers take note.

I prefer a wood chisel of the appropriate width.

[–] CameronDev@programming.dev 1 points 6 days ago

And make your chisel blunt and chipped? You monster

[–] WhyAUsername_1@lemmy.world 1 points 6 days ago

I think it's better to plug it with Hot Glue
