Some Ryzen Linux machines still stumble along despite efforts to fix it all

    I don’t know why I keep hearing of security measures to stop someone sleuthing into bootloaders.

    Am I the only person using Linux who isn’t James Bond?

      I’m an engineer with trade secrets on his laptop. I’ve heard of dozens of people getting laptops stolen from their cars that they left for like ten or fifteen minutes.

      The chances are slims, but if it happens I’m in deep trouble whether those secrets leak of not. I’m not taking the risk. I’m encrypting my disk.

      It’s not like there’s a difference in performance nowadays.

        TPM’s not going to help with that situation, though, right? Either you’re typing in your encryption password on boot (in which case you don’t need TPM to keep your password), or you’re not, in which case the thief has your TPM module with the password in it.

          From what I understand, TPM is “trusted” because of the fact the secrets it contains are supposed to be safe from an attacker with hardware access.

          This is what makes it good at protecting data in case of a stolen laptop. This is also what makes it good at enforcing offline DRM or any kind of system where manufacturers can restrict the kind of software users can run on their hardware.

      It’s 30% legitimate concern over a non-negligible risk of government overreach, 70% having fun pretending to be James Bond.

      I mean, i do have some stuff that i encrypt, but encrypting the folder or packing it on a small partitiin and encrypting only this fs after booting makes more sense to me.

      I’m still on the hunt for a desktop Linux distro that has no security features or passwords. My usage for this may not be common but it can’t be rare enough that there are zero options

        Ubuntu, no encryption, select boot to desktop by default when the system installs.

        Like, really?

            Ah so you want the windows 98 experience, root access by default all the time without passwords or extra prompts.

            Maybe setting auto login and sudo without password can be almost enough? https://askubuntu.com/questions/147241/execute-sudo-without-password

            I agree that there should be an easy setting to at least allow updates without password. I installed Manjaro for my mom, after a while she complained “there are updates every day and I need to input the password too many times”

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.
