so I just tried live legacy kernel AntiX and brightness worked fine (every other distros brightness never worked) so i installed it and guess what, brightness doesn't work. I don't know if it installed legacy or modern kernel I don't remember if there was a choice.
My question is if its better to have legacy kernel since i got a laptop with 4th gen i5? The rest of the stuff works like every other distro does... there was another distro that i've tried and brightness also worked but i can't remember which one. I just can't get brightness to work

Hey everyone!

I’ve got a big idea, but I need some help figuring out if it’s even possible. I’m a junior programmer, and I want to make a gaming-focused app, kind of like WinApps, to make Linux gaming easier and better.

The idea is to run a special, stripped-down version of Windows Pro inside a virtual machine (VM) on Linux. This version would be optimized for gaming, so it runs as smoothly as possible. The cool part is that I’m thinking of adding something to block cheats that use VM exploits. It would basically be an anti-VM system built right into the VM itself. On top of that, I want to try working with anti-cheat developers to get this system whitelisted, so it doesn’t cause issues with games that have strict anti-cheat systems.

Linux gaming has come a long way, especially with things like Proton and the Steam Deck, but it’s still got problems. A lot of games don’t work because of anti-cheat systems, and current virtual machine setups aren’t great for gaming. My goal is to solve these issues and make Linux a legit choice for gaming—no workarounds or compromises needed.

Here’s where I need your help. Is something like this even possible? Could we really build an anti-VM system that blocks cheats, and would anti-cheat companies actually work with us to whitelist it? If you’re experienced with virtualization, security, or gaming tech, I’d love to hear your thoughts. Even if you’re not a developer, I’d still appreciate your ideas and feedback—what challenges am I not thinking of?

I’m just getting started, and I’d love to get more people involved. If you know about virtualization tools like QEMU or KVM, have insights into anti-cheat systems, or just have some ideas to share, let’s chat. Even testers and people willing to spread the word would be a huge help.

I really believe Linux could be amazing for gaming, and with the right tools and support, we can make it happen. What do you think? Does this sound doable? Let’s talk and maybe start building something awesome together!

A lot of modern terminal emulators, like Alacritty or Warp, are written in high-performance languages like Rust. And if I understand correctly, they leverage the GPU to render the terminal window, and run a separate process for the actual execution of commands. What does it actually take to build one of these terminal emulators and what makes them complicated?

Where does the funding for Linux development, including both the core Linux kernel and the Linux desktop ecosystem, go? How is it allocated across key projects, individual developers, infrastructure, and community-driven initiatives that support the ongoing growth, improvement, and adoption of Linux as both a server and desktop operating system?

Hi,

I'm trying to find learning material for linux networking, for someone who is network engineer "CCNP level" by profession, but also holds RHCE, i would like to combine the linux knowledge with the network knowledge, something like that, any book, course, youtube, labs and so one to teach the following concepts in linux world?:

• Routing

• Switching

• Firewalls

• Proxy

• Bridges

• NameSpaces

• iptables

• Docker networks

• openswitch

• vswitch

• software defined networks

and so on if there is such book or course that is fitted for linux networking?

THANKS

Hi, I’m pretty new to Linux, but I’ve been excited about making the switch for a while and I’m really enjoying it. Unfortunately I’ve noticed there’s a pretty big amount of doomposting in Linux communities about how “FOSS is dead” or “Linux is in decline.” Is there any truth to this or are people just insane doomposters?

BootSelector is a tiny GUI utility for setting any grub menu entry as default.

It also allows you to reboot into any OS/kernel in your grub menu.

The initial version has been tested on the latest Ubuntu 24.10 and should work on other Debian-based distributions as well.

An RPM for fedora will be released soon after more testing is done.

I have only ever used mint seriously, as I’m getting more into the Linux space, what do you guys think I should try next fedora or arch? After using Mint for around a year and a half I can say confidently that I have become more tech savvy than I was from when I began this journey

The AlmaLinux 10 Beta has now been released for testing and its looking good.

Highlights are:

• Kernel 6.11.0-0.rc5.23.el10
• Gnome 47
• Spice support re-enabled for server and client
• x86_64_v2 support (RHEL is v3 only going forward)

https://almalinux.org/blog/2024-12-10-almalinux-10-0-beta-now-available/

Beta ISOs are available at repo.almalinux.org.

Release notes are available on the wiki.

turn computer into a phone gui > use software to mirror computer screen to phone > use phone to remote control computer.

the idea i basically to turn the computer into a phone and use the phone device as just a type of input control.

So, being new to Linux, and looking for a summary of the patch notes, I was referred to a Linux newbies site. However, while it contains very good information for minor versions, it does not cover patch versions. Since https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.12.4 is way too verbose to be a summary, I asked AI to help per https://www.reddit.com/r/linux/comments/1hbfsgv/kernel_6124_changelog_summary/, but I felt it was still too generalized. So, I rolled up my sleeves a bit. Enter lkcl, a tiny-ish script:

The following will grab your current kernel release from uname and spit back the title of every commit in the changelog, sorted for easier perusal.

lkcl

The following will do the same as the above, but for a specific release.

lkcl 6.12.4

While I'm not an expert here, here's my first stab. Improvements are welcome, but I'm sure one can go down a rabbit hole of improvements.

Cheers!

I just saw a post about how Mint has risen to the top of the popularity list at Distrowatch, beating out MX. We hear a lot about how Mint is great for beginners coming from Windows because the UI is familiar.

That got me thinking. What is the least Windows-like, or most Linux/Unix -like distro? What takes the most traditional *nix approach, whatever you think that may be?

I suppose if I wanted something that looked more traditional I'd go through the effort of using NsCDE. Another part would be using something that hasn't adopted systemd.

Thoughts?

Hello you guys, I’m currently on my last week of my college semester and plan on allocating the next 4-5 weeks to receiving my Linux+. I bought a course on UDEMY called “Linux Administration: The Complete Linux Bootcamp in 2024” and would like to know if anyone else has taken this course and can tell me how good it is? Along with the course, I plan on practicing within a Linux VM and watching YouTube videos on Linux whenever I’m not doing anything. but I would also like to know any resources that you guys have you used to better prepare you for the test. Thank you for any given advice!

Hey all! I've been a basic Ubuntu user and command line user (web dev, managing VPS stuff).

Goal: I'd like to have a PC with a powerful graphics card for:

• Video Editing
• 3d modeling (whether it's CAD, or Blender, etc)

I know that sometimes there are certain brands to favor or avoid, based on whether drivers are readily available/reliable.

If these are my concerns, where's a good place to research compatibility for:

• CPU
• Graphics Cards
• Wi-Fi cards

When it comes to using something like Fedora or Ubuntu? I know Ubuntu has a "certified hardware" list of laptops, but if I were to build from scratch or look for something used, I might not find an "exact" match, not to mention that Ubuntu's list can be very long…

Thanks for any direction you can offer!

Edit: I am researching, but one never knows if an article in the wild is skewing to a particular brand, etc. I'd like to hear from daily users, not a blogger.

This is the only hole in my open source software. I use Master PDF Editor to edit PDF text, and it works great, but is proprietary.

Has anyone tried pdf4qt (https://github.com/JakubMelka/PDF4QT)? Can it modify existing text on a PDF? I haven't tried it because it is not in the Ubuntu repositories, although it does have a Flatpack.

Is there any open source program I'm missing?

Note that I'm talking about modifying existing text. I'm not talking about "editors" in the sense of merging PDFs, or annotating them (which Okular and Xournal do a great job of but from what I understand cannot modify text). I'm also not talking about importing a PDF (I think Libre Office can do this?) because it can change a lot how the PDF looks.

The relevant part

Finally, the onboard technologies are open source. The operating system will be the free Linux, both for the vehicle's basic mechanisms and for the ADAS, which controls safety features such as automatic braking and cruise control. According to the businessman, the choice of open systems allowed the cost of developing proprietary technologies to be reduced. “We brought these features to the car, which became much cheaper and faster to develop. We are internally testing our system to even control a Corolla, for example,” says the executive.

So, being new to Linux, I wanted to find a nice summary of kernel minor version changes, but all I could readily come up with was https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.12.4, which is quite the read!
