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.

Any way to autologin with LUKS encrypted boot drive? (lemmy.ml)

Hello everyone!

I daily drive a Nobara install with my main drive being an LUKS encrypted M.2 drive. Every time I boot my computer I get presented with the password prompt to unlock the drive and afterwards get prompted with my login manager to login.

Is there any way to combine these steps into a single prompt? It is starting to get a bit annoying having two steps every time I boot.

Several Display Managers support auto login. For example :

Thank you very much. The DM setting where shuffled a bit in Plasma 6, but I managed to find it under SDDM > Behaviour.

Be aware that kwallet will require you to enter your password if you auto-login. Kwallet usually saves your passwords for wifi etc. That's why auto-login with KDE doesn't make much of a difference in most use cases

Can you configure KWallet with no password? Often you can do something like set an empty password and it will auto-decrypt with no prompt.

This may be undesirable as apps running in your user can access what is in KWallet but honestly this is probably the case anyways. If you are running unsandboxed untrusted applications you have already lost.

This is fine for my use case. I don run wifi on my gaming rig but I guess I'll see if any other things prompt me for password after logging in next time.

Edit: Nope, I have no clue what is even possibly stored in Kwallet, if anything, but it still pops up and requests password. Ironically i went from typing my password 2 times to 3 times by enabling auto-login. I know have to unlock the keyring once I login, and then unlock Kwallet once I try to launch Discord. We love it.

It's fairly common for apps to save login information in Kwallet on your keyring, so anytime those credentials on your keyring need to be accessed (like automatically logging into Discord when it starts), you will need to unlock your keyring. It's generally easier to just log into your profile with a password, as Kwallet won't need to get you to unlock it separately.
