Elgato 4K X 5Gbps -> 10Gbps link fix
So I had this obscure problem with Elgato 4K X not connecting to my 20Gbps USB-C port in 10Gbps mode. Hence, I wasn't able to actually stream/record gameplay from PS5/XBox Series X/Switch and other devices I own in Y/UV 4:2:0 4k/60Hz and had to use MJPEG which adds extra latency and crushes colors a bit.
I’ve solved it as follows:
1 — Force the card into USB 3.2 Gen 2 (10 Gb/s) with Capture Device Utility Host: macOS 14.4 (Sonoma) Tool: Capture Device Utility 1.3.1- Plug the 4K X into the Mac.
- Launch Capture Device Utility → select the card.
- Hold Option (⌥) / Alt – an extra toggle appears.
- Enable USB Gen 2.
- Disconnect the card.
If you skip these steps, the device stays in 5 Gb/s mode even after updating the firmware.
2 — Verify 10 Gb/s on Linux lsusb -tExpected (note the 10000M lanes):
/: Bus 012.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/5p, 20000M/x2 |__ Port 001: Dev 008, If 0, Class=Video, Driver=uvcvideo, 10000M |__ Port 001: Dev 008, If 1, Class=Video, Driver=uvcvideo, 10000M |__ Port 001: Dev 008, If 2, Class=Audio, Driver=snd-usb-audio, 10000M |__ Port 001: Dev 008, If 3, Class=Audio, Driver=snd-usb-audio, 10000MIf you still see 5000M, repeat step 1 — the switch didn’t stick.
That’s it: once the link reports 10 Gb/s, the 4K X has enough bandwidth for Y/UV 4:2:0 4K/60 captures.
If anyone more knowledgeable comes here -- is there anything we can do on Linux side to set this 10Gbps flag instead of having to use Mac? Do I need to research how to send USB ctrl transfer packets? Possible to figure it out on my own?
E.g.
# Some Python script import usb.core, usb.util VID, PID = 0x0fd9, 0x00ef # Elgato 4K X REQ_TYPE = 0x40 # Vendor | Host‑to‑Device BREQUEST = 0x51 # ← figure out from dump WVALUE = 0x0001 # ← «enable Gen2» WINDEX = 0x0000 DATA = None # no payload dev = usb.core.find(idVendor=VID, idProduct=PID) assert dev is not None, "4K X not found" dev.ctrl_transfer(REQ_TYPE, BREQUEST, WVALUE, WINDEX, DATA) print("Mode switch request sent; replug the device.")Also one more problem I discovered yesterday: when I try to both record video & audio, I hear clicks/pops when using Y/UV 4:2:0 4K/60 mode. It goes away if I switch to MJPEG and/or lower resolution to 1080p. Seems like USB link saturation? usbtop indeed shows 800-950MB/s with 4K60 4:2:0 stream, which is very close to practical limits. I'm also thinking it might be due to my Proxmox/Arch setup or maybe my Ryzen 8500G isn't fast enough (OBS capture only seem to load one core at around 50%)
You can observe these popping artifacts at first 20 seconds of this stream. The only solution I came up with is to use something like HDMI-splitter to extract audio -> send it over my USB Audio interface (Behringer 404HD) -> route into OBS.

SFG OS Follow-up
Hello everyone! I posted here around 3 months ago about my package manager and Linux distro. I wanted to talk a little bit about it because I have restarted the distro portion of the project. I was very close to finishing the first GUI/DE part of the distro but I completely restarted. Since that post, I've made some significant advancements across the project! For Starpack, I've completely switched to zstd compression, which has proven incredibly efficient for size and speed (thanks for the recommendations BigHeadTonyT and others.) I've also significantly sped up parsing and saving operations by utilizing SQLite, and crucially, I've lowered the dependency count considerably by moving away from libcurl.
Beyond Starpack, the core of SFGOS is evolving rapidly. I've created ~63 custom coreutils based off of BSDCoreUtils to replace the GNU ones, and I'm thrilled to announce that their source code will be going live very soon, most likely when I wake up later. To further enhance performance and reduce bloat, I'm making a strategic switch to musl libc. And on the shell front, I've developed my own custom shell called ReefSH, whose source code will also be released in just a few days! (after ironing out a few more bugs) Despite restarting the distro's development, I have made a lot of advancements to the software and distro itself.
The custom components like Pulse Desktop and the graphical setup assistant are still key parts of the roadmap, and I'm very excited about the progress on the core tooling. I am also switching away from systemd, as it is extremely bloated and huge. I will maybe use openrc or make a custom init system, we will see what the future holds.
I know this might not be really within the typical scope of a Linux gaming discussion, but I wanted to provide an update on the underlying development that will ultimately benefit SFGOS's performance as a gaming-centric distro. Your feedback, questions, and ideas are incredibly valuable as I continue this journey. Please remember that I am one person, that rarely has friends help out with code (except on reefsh and the coreutils), so I can NOT do everything correctly, for example, my code is not perfect at all. But I have stayed up entire nights to ensure I tried my best. If you wish to help out with the code, I would genuinely appreciate it.
Thanks for your continued interest and support. I look forward to sharing more updates as SFGOS gets closer to a public release.

White flashes in some games when opening/closing menus, only when HDR is on?
On fedora 42 with KDE plasma. I've got an OLED HDR monitor, but in some games (minecraft pictured, I've also noticed this problem in dune awakening, haven't tested many others) whenever I open/close menus I get this white flash on my screen that's really annoying. Had to record with my phone because it doesn't show up in a screen recorder - tbh it's also more noticeable in person than in the video but you can still see it. This only happens when HDR is enabled in KDE plasma settings, so I can workaround it by turning it off but that's kinda annoying cause some games I play do have nice HDR support (through gamescope) so having to turn it on/off when I play different games is a little annoying.
Monitor: MSI MAG 273QP GPU: Radeon 9070xt CPU: Ryzen 9800x3D
Lmk if there's any other info that would be useful.

I hate processing vulkan shaders :c
I download a new game to play with the boys... they're waiting on vc as I say "Haha fellas it's downloading..." but... it finished downloading... it finished downloading 5 minutes ago actually... As I stall more and more... I look onto my monitor and there's only the pop up. "Processing vulkan shaders: 52%". I wait and wait, each millisecond feels like an hour... "play one without me haha its still downloading" and I just sit there quiet as they have their fun. Maybe I'm a weak man, but when I come across an issue and mention it to my friends, they laugh and say "haha its because you're using linux" and I feign laughter, but deep inside, I'm hurt. I know it's not perfect, but I appreciate what else it has giving me. However, I know that no matter what, I'll always be a bit late. Sorry bros, I have to let my pc process vulkan shaders for 15 minutes.

Mesa 25.2 NVK vs. NVIDIA R575 Linux Graphics Performance
I'm trying to get The Witcher 3 Mod Manager exe working with Protontricks Launcher, but I can't find my game's exe directory. (I'm on Bazzite). What exactly the easiest way to get The Witcher 3 mod manager working?
I want to get back into The Witcher 3, but I want to mod it first. One of the first things to install besides Script Merger is the Mod Manager. However, it looks like I need to use something like the ProtonTricks Launcher (I tried just ProtonTricks, but it wouldn't open anything). The PT app wants me to find my Witcher 3 exe through this awkward small screen that you see on the top left, so I go to "my computer, C drive, program files X86, Steam, Steam apps" and I just come to a blank screen. I tried every other pathway, but I can't find my Witcher 3 game.
What should be an easy install process is turning into an annoying and confusing puzzle game. I would be grateful for advice.

volt-gui 1.0.0 released: A Linux optimization tool focused on performance and ease of use
Hi there lads, I’m here to announce that volt-gui has officially reached its 1.0.0 release.
If you're wondering what volt-gui is, it's quite simple: a simple GUI program for modifying and creating the "volt" script and more. It provides an intuitive interface for configuration management, with the goal of squeezing out the maximum performance possible from a Linux PC.
You can change your CPU governor, start or kill scx_* schedulers like lavd or rusty, and tweak a wide range of kernel values to alter system behavior. Don’t worry if something goes wrong when you restart the PC, and everything reverts to the default boot values.
You can also choose values for a very wide variety of GPU related environment variables. All of these have been extracted from official NVIDIA and Mesa documentation, and in some cases from Freedesktop documentation. I’ve spent quite a bit of time digging through all of that, even reading source code as some of those aren't even documented :/.
The whole point of the project is not just to give you the tools to fine tune your system for gaming or performance, but to do so in the most user friendly way possible. A good example of this is in the GPU section: you can simply select an OpenGL and a Vulkan renderer. That’s it. The program will detect the available renderers on your system (just make sure you’ve installed the requirements), and once selected and applied, it will add the correct parameters to use that driver to the volt script.
I built all of this to make the transition to Linux easier for my friends switching from Windows 10, keeping things as simple as possible.
I’m already very happy with what the program can do, but if you want more features, feel free to open an issue and tag it as a [Feature Request].
Here’s are some images of the program:

Performance uplift in Rimworld compared to Windows
For context, I've dualbooted Linux on and off ever since I was in college. I preferred Linux and liked tinkering, and would occasionally try games on Linux, but my laptop at the time with an nvidia card didn't play very nicely so I avoided games in general. Fast-forward to now, I've recently started dualbooting again and to my surprise a lot of games have been working pretty fine. I play league, so obviously I can't fully migrate, but otherwise most of the games I play have worked as well as on Windows or with minimal fps losses
Rimworld specifically had a performance-related benefit that was actually noticeable: zooming out fully on 3x speed was pretty taxing for my computer on Windows as soon as I got more than 6 or so colonists, usually leading to my frames dropping from a constant 144 to inconsistently spiking below 80. On Linux I still have a performance drop doing that, but it's sticking to around ~110-120 fps without any spikes, and chilling above 130 if I'm not moving my camera around at all. I don't think it's being limited by my specs since I have a 5800x3D and a 9070xt, so I imagine it's something to do with Windows vs Linux CPU scheduling or something, but I'm not really knowledgeable on those specifics. Either way, this was a pleasant surprise. Once I figure out some things like discord screen sharing and input remapping on my dualsense, I might primarily play games on Linux and save my windows partition just for league lmao

Last Of Us part 1 has busted my pc
I was playing Last Of Us Part 1 on CachyOs when my whole system turned off by itself. I cannot power it back on, even after reseating RAM removing CMOS etc. Could my psu, Aerocool Integrator, have fried or could it be that the Mobo Asus A320m-k have died. Not particularly Linux related question but I need an answer nonetheless.

I can't seem to download Bottles (which apparently runs Windows programs) without having to donate. Is this worth it or a scam?
I'm new to Bazzite and wish to start modding The Witcher 3 with its own mod manager. But it looks like I have to use some program that would help me access Windows applications like this mod manager. I came across this video about modding on Linux https://youtu.be/7YrBUMnnCNs?t=90 , where it recommended a program called bottles. When I went to go download, it wanted me to donate some money. There doesn't seem to be a free option.
Is this a scam? Or is it worth donating at least 1 dollar to utilize it? Or is there a free version that I can use?

Desktop entry fixer
When I am playing games on linux, usually I got annoyed by the gear icon showing on the opened game (normally a proton game) and not the right game icon. So I study it a little and notice that native games usually show it just fine, so analyzing their desktop entries I notice what is wrong: StartUpWmClass is missing from any other game. I did a script in rust (I am learning this week, so sorry if its not that good haha) to automatically fill this field and consequently shows the right icon. Feel free to use it and ask me on github to improve or fix it :)
Known Issues:
- Does not support some native games since they dont follow the same pattern
- Does not mess with the file neither
- Does not support non steam games (WIP)
- Same
You can see the installation script if you want to give a try. Also its important to say that this does not consume too much resources so its just fine to keep it in background (uses 1.5 - 1.8 Mb ram).

Will Intel Arc ever be good?
I am looking at probably switching to Linux, and am considering upgrading my 2060 as well, and Arc is so tempting for the price, but sounds like a terrible idea. Anyone think it will get worth it?
