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.

I was kinda annoyed at double password login when I setup my system too. So what I did was just enable automatic login for my user since I’m the only one. I just treat my disk password as my login form so I just enter one password. I still have a user password for things like sudo and other permissions handling when I’m logged in but getting into a new session is automatic on startup so it doesn’t annoy me anymore. Would that work for you?
That's exactly what I do lol.
I think this is what I might have to do as I really don't want to go back to Windows. I don't suppose if you know if there is a way to lock the drive upon logging out? Or do I need to do a full shutdown every time.
Move your swap to encrypted part of your drive and suspend to disk. ;)
IIRC and I may be wrong here the drive stays encrypted in sleep. Decryption is done in real time via your CPU. However the encryption key is stored in unencrypted RAM. Which is why the other comment suggests encrypting swap and hibernating, this writes RAM to disk.
I’m not sure LUKs can lock a drive that’s booted already since it’s not a RAM session like a live CD is and relies on the decrypted files to operate. This is why the encryption key is prompted from your boot manager prior to actually getting the system running. That said, I lock my computer all the time and just rely on the normal user password to get back in.
Same. Not at all interesting.
Boot up password -> ATA DriveLock password -> LUKS FDE password -> Login password, that's where it's at.

It's just funny situation if you forget the DriveLock master password. Yes, it has 2 passwords. The master password is needed to remove the user password which is used for unlocking. If you forget the master password, you can't ever reset the user password. If you forget both, you upgraded the drive to a paperweight. Additionally, some BIOSes may do hidden key derivation, store the master password in TPM, or do some other crap, so it's generally not recommended unless you actually need it.
This can also be set in
hdparm.Also, I have no idea what way there is for NVME drives, as this uses ATA commands. It's also good to note that some drives use this for hardware-based encryption, and some don't. So it brings varying security.
That's why I have a password manager on my phone.
