Steam says they've dropped support for the steam browser on 32-bit Linux systems. Does this mean I'm unable to play the games I own through steam on my 32-bit Linux machine?

I have an old computer which unfortunately is 32-bit afaik from doing lscpu with it telling me I only have the one opmode for 32-bit processing. When I installed steam on it, none of my games would display in my library and there was just one notification in the top left of the window telling me that the steam browser wasn't working correctly with a link as to why.

Following the link; it explained that Steam has dropped support for 32-bit linux systems.

Does this mean it's impossible for me to install/play my purchased games on my computer? Or is there a workaround? Most of my games are old games anyway.

How and why is UEFI's Secure Boot useful?

There has been some discussions around SecureBoot recently, which a lot of it prompted by Intel's clearlinux team saying that they do not support Secure Boot. I wanted to clear several misconceptions on the matter.

>1) Secure Boot is a microsoft product.

No it's not. It's part of the UEFI (Unified Extensible Firmware Interface) standard that evolved out of Intel's EFI replacement for legacy IBM-PC bios.

UEFI is a defined interface that is presented by a motherboard's firmware to allow conforming operating systems to interact with the platform hardware. Secure Boot is nothing more than a standard for comparing cryptographic signatures on bootable executables and some OS code against a database of keys. [https://www.intel.com/content/www/us/en/support/articles/000006942/boards-and-kits/desktop-boards.html](https://www.intel.com/content/www/us/en/support/articles/000006942/boards-and-kits/desktop-boards.html) . In pretty much all x86 motherboards (by which I mean I can't find any exception,) the key database is entirely controllable by the end user. If you want to add your own key, you can. If you want to delete microsoft's key, you can. The only way that microsoft is involved is that 1) the majority of motherboards ship by default with MS's key, and 2) for a computer to be designated "Certified for Windows 8 or 10 or whatever" it has to ship with Secure Boot enabled by default and have Microsoft's key. It does not prevent user management of the keys.

Many distros have partnered with windows to piggy-back off their keys since they're distributed by default, but this is only relevant for REALLY new users who cannot manage their own key store. It's entirely possible to get the signing keys of your distro or to sign your own stuff without using MS's key at all.

​

>2) Secure boot is meant for enforcing DRM

Secure boot isn't even capable of enforcing DRM by itself. Once the OS is loaded Secure Boot doesn't do anything, it is only capable of restricting execution of boot loaders and OS kernel / modules. Most people confuse the criticism of secure boot with the criticism of hardware TPMs (trusted platform module). A TPM is a hardware device that contains private cryptographic keys with a defined interface for decrypting data without exposing your private key. In theory a company can require a TPM that does not expose an interface for user management of the keys and use it to restrict what devices are authorized to use its software or view media. Essentially a dongle. For that to be effective you'd have to enable both a TPM and a bastardized version of secure-boot that only allows heavily restricted operating systems to boot so that someone could not just load the software, find the unencrypted version of the software / media in RAM, and dump a cracked version that bypasses the DRM. But there are no examples of this type of thing being done on consumer PCs since most don't come with a TPM, and most users are not computer savy enough to understand how to buy / install / use one.

>3) secure boot doesn't protect anything or isn't useful.

It is entirely possible that your specific use case and risk tolerance is such that it is not an overall benefit for you to use secure-boot, but there are real benefits to it. If you dual boot your computer with both Windows and Linux, and have encrypted your Linux main drive, you still have unencrypted files that are used to bootstrap your computer enough to unencrypted those files. Even without a filesystem driver in windows that can read a linux partition, there still exists a theoretical attack where someone could compromise your windows OS, modify your initramfs, and put in some code to sniff your decryption password, writing it back onto your windows system to be retrieved the next time you boot into your compromised windows. SecureBoot prevents this attack, and even if your windows system is compromised by someone without a private key matching your secure boot key database, your linux boot files cannot be modified. If you only run o

ne Linux distro, it's much less beneficial since a compromised Linux system that allows modifying boot files would mean access to anything else, but it would still prevent certain theoretical classes of attack.

​

I'm certain I missed something, and am open to discussion or debate, but I wanted to clear up a lot of confusion and myths that seems to exist.

KDE is crap

Is it just me or is KDE the most buggy desktop environment out there. Everytime I try installing KDE plasma in a virtual machine. VMware Tools, Open VM Tools, VirtualBox Guest Additions and nothing else works.

KDE looks great but is disfunctional as hell.

That's not all. Plasma constantly crashes. Windows (graphically) sometimes glitch up (that one could be due to it running in a VM though)

Having issues downloading for browser. Secure Connection failed

I recently downloaded a fresh install of Linux Mint 19.3 cinnamon and have been tailoring it to me taste. I am trying to download the tor browser but every time I access the website through Firefox or Chromium I get “secure connection failed error code: ssl error ex record too long” I’ve tried some fixes some people have recommended and still get the same problem. If anyone find or knows of anything that can help out I really appreciate it.

plank dock in openbox and lxde missing features

hey guys, newbie issue with plank. I am missing transparency and icon zoom in openbox and lxde, while in xfce it acts much better.

Am I missing something in openbox or is it simply not supported that much like more robust DE and WM ?

Noob question about dsd audio files in li ux

Hi,

my aim is to build up a linux computer as an audio player for my audio files that are stored on a QNAP NAS. I bought myself a used Lenovo Thinkpad and managed to install Linux Mint onto it. I will use JRiver's Media Center to play my music files. This works fine so far for my HighRes Flac files. The one thing that doesn't work "out of the box", is playing DSD files and I wonder if there is need of some codec files to support DSD files. Maybe some of you can help me out here. Or is there a Linux system out there that is "better" for streaming and playing audio files from a NAS into a DAC via USB? The JRiver Media Center isn't tested for many distributions though and I would like to stick to it.
Thanks for any tipps, as I am quite new to Linux and wouldn't know where to search and look!

What are some useful ls* commands

I'm pretty new to linux, but I've found that the ls* tools (e.g., lsblk, lsusb, lspci, lscpu, lsof, etc.) are supremely useful. It seems like every day I watch some tutorial and learn about another one I hadn't heard of before (just learned about lstopo from a Level1Techs video).

Is there a list somewhere of all the ls* commands? What are some other ones that you know about?
