r/cachyos

I'm an old-timer Linux user (started with Ubuntu 14.04, 12 years ago). I've always switched between stable and cutting-edge distributions since (Ubuntu, Debian, Fedora...). I've been using CachyOS for a full year now (on my desktop, with KDE Plasma for gaming, and on my laptop, with Gnome). I've never had such a good experience on Linux ever, either on my desktop for gaming on my Intel 12700K/RTX 3080 on KDE Plasma (which has the best gaming performance) and on my AMD Ryzen AI 9 HX 370 on laptop with Gnome, which has just perfect work efficiency. I'm a forever Gnome lover, and I think I have found the best balance for all my usages.

Thank you for this incredible distribution, its incredible performance for all DEs, and it's stability.

Here are a few wins:

- On my desktop, I'm playing a lot of games without any difference compared to Windows. I've finished Clair Obscur, many Nintendo Switch games with Eden, Spiderman 2, TLOU 2, and many others, without a single glitch/crash. It's the first time in my Linux gaming experience when I can't tell that I'm not using Windows.

- On my laptop,I can use my NPU to generate daily tech radar reviews with OpenClaw, with very low energy and a great stability, and do many tasks in parallel. I installed a lot of exotic things on my system, and it remains stable as hell, plus I have security with Limine.

Thanks a lot for this incredible Linux experience, it's the first time in my life I have never ever needed Windows for any task.

i love linux but i cant play a game fix this error and new errors coming my pc specs ddr5 16 gb ram rtx 4060 intel i7 12 th msi cyborg 15avf laptop i installed all drivers all packages but i play a game with lutris i have errors with nvidia graphics card and i tried every thing
im very loving the linux but i cant play and decided to back laggy shitty windows 11

After 20 minutes approximately playing SOTF in my pc, when I open the inventory the fps drop and GPU usage scales to 100%.
Also after 2h approximately the fps drop and the game starts going quite bad.
I’m using proton-experimental to launch the game, because I saw it worked properly.
What can make this issue?

I switched from HDMI to DP. The HDMI port on GPU has become flakey and sometimes drop the monitor signal. With HDMI, PC would turn off display and go to sleep. Now with DP, it doesn't do any of that. Why the difference? I'm running an AMD 7700x and 6700XT on an ASUS ROG B650E-I mobo. Anything I can do to change the behavior? TIA!

I have a LOVINGCOOL DP-360-02 and the problem I have is that the software doesn’t detect it when using wine. I made a windows partition to change the screen (which it worked nicely) but that would give the problem where every time I restart the PC I have to go back to windows, and open the software or it would just stay as the default screen image. I’m not sure what to do I’d just like to stop needing a windows boot 😭

I installed the most recent update, and now I can't open any programs. I did nothing else, just updated through flatpak. When I attempt to open Discord or Firefox or tge settings or the command prompt it just loads and doesn't open. On top of that, the login screen just doesn't show, it just goes straight to desktop despite having set it to need a password when first installing. Not even the shut down and restart options work, I have to shut it down manually!

I am a long-time linux user, primarily Ubuntu-derived distros such as Mint.

I dual-booted Mint and Windows 11 for a long time, until I started to get annoyed with MicroSlop and went full Mint last year.

But, as someone who likes to explore and try new things, I caught wind of CachyOS, and watched a ton of videos on it. I decided to try it for myself, nuked my Windows 11 install, and went full CachyOS this last weekend and could not be happier!

Problems that plagued me on Mint just don't exist here, probably because I have up-to-date packages and a current kernel.

Much love to the CachyOS team, and thanks for creating an OS based on arch that is user-friendly and demonstrates why those that use arch rave about it all the time. I get it now!

I could make this a long post, and I've written long posts before, but I've been accused of AI slop too many times now that I frankly don't even want to invest that much time in riffing something out of my fingers.

Still, this part wants to be written, we'll see how far we get.

My journey with Linux began with Ubuntu about 2 decades ago, an elderly person in my family just wanted a basic laptop for email/youtube/news and that was it. That's when I first installed and tested it myself, and I knew, they'd never have issues with getting all kind of spyware installed where the browser suddenly has all these extra tool/spy-ware-bars added. Or all kinds of supposedly anti virus software. I knew Ubuntu would be zero maintenance on my end given their known use case. They would never care about games or performance and so Ubuntu was perfect.

Wait, why am I recounting history, that makes it long, but TL;DR: Ubuntu -> Mint -> frustration with multi monitor setup -> search for better alternatives -> KDE -> Arch, but didn't care to go through the full setup process, I was looking for good defaults such that I could recommend the OS for another future family/friend -> Manjaro

Staid there a little over a year. Didn't really have any issues with it, and still don't, I have it as my backup/most-stable/tested OS installed still. Manjaro is the first that became my own daily driver, where I discovered KDE and fell in love with Linux for the first time. Finally, proper multi monitor setup support. I was sold. After about half a year of tinkering and tweaking it to my preferences, I finally happily deleted my windows partition. My love for Linux kept growing. Mostly thanks due to KDE frankly, it's so extremely config-able and in essence starts of being similar enough to Windows in design that it made the transition very simple.

So then why am I now here on r/cachyos?

During my Manjaro discovery, I ended up learning about BTRFS, because I saw it as an option in Timeshift and because the backups/restore-points were taking way too long to my liking, I ended up looking up what btrfs meant. I quickly understood I wanted to try it. And so I ended up converting my OS to BTRFS and modified the OS such that it would automatically create snapshots on every update and automatically these entries into grub. None of this was default. And it further encouraged me to keep tinkering with the OS, this time, knowing that I have instant backup & restore available at my finger tips.

Eventually, I realized, I wanted to start form scratch, too many changes & modifications happened, I strayed too far from the distro defaults to my own liking. And I started looking around, native boot-able BTRFS snapshots became non-negotiable and any distro that doesn't natively bake this into their entire design philosophy just doesn't make sense to me anymore (other than nice use/server-cases of course)

I knew that eventually I want to step back into the corporate environment, I want to convert as many people to Linux and recently figured out I will be targeting high schools specifically. Old enough to learn new habits. Not too old to stubbornly refuse to change their ways. And so with this in mind, I ended up on Tumbleweed. Close enough to enterprise support Leap, I wanted to get familiar with that environment. And earlier this week I finally downloaded the iso and started installing. It was not a pleasant experience. And especially not when I found out the installer doesn't even have a live-OS option, enough things went wrong such that I needed to download a Manjaro install/live-iso and flash it on a USB to rescue my system. Luckily I have an 10 year old laptop laying around with a super old Mint install still acting as my backup system for cases like this. I was baffled that opensuse wouldn't include liveOS functionality in their installer image. After tinkering for 2 days on Tumebleweed I finally was done and got it functional enough to be viable to switch over from Manjaro. But I wasn't happy with the entire experience. The sheer bloat of software/package-management GUI's, urgh. I just couldn't ever see myself recommending it to tech-noobs. There were like 4-5 software managers/variants, how am I supposed to know which to use and why?

So today, since I already knew about cachyos, my curiosity drove me towards overwriting the entire disk with a cachyos install instead, it's not even been an hour or so since my install. And everything ... just works? Nvidia drivers included.

And ... 1 software/package GUI easily find-able through the start menu. It started with asking me which software sources to include. I already knew, oh yes, oh fuck yes, this is what I want, all gathered and brought together in 1 portal, with some proper warnings in place for certain sources/methods of course.

I didn't even need to find out which driver to install, it was already taken care of by default.

And then the terminal, initially, a bit frustrated with the seeming bloat start message of system OS stats. But quickly loved how it's subtly guiding people towards learning how to customize their CLI, which ... was extremely easy and seemed to serve as mini tutorial. Brilliant.

All my main apps, all directly find-able and 1 click install in 1 unified GUI. I'm so happy.

Proper defaults. Very user friendly. Zero hassle. Good installer relying on the liveOS, which yay! I knew for sure it was by default included. Which is another good design choice, no matter what gets bricked, I can always plug the installer USB and get access to a nearly fully functional OS (a browser + easy GUI to manage internet/disk is really all you need for rescuing an existing OS)

This feels like the future of Linux. Sound design all around.

The only thing I still worry about is stability, but that will only reveal itself to me over the coming months just like Manjaro has earned a certain amount of trust over the time period I was on it. I am hoping to get similar perfect stability here on cachyos.

If so, I finally found the distro with proper defaults that I will be recommending to everyone.

It just works. And you retain full Arch freedom to remove/modify whatever the hell you want.

Thank you, to everyone who contributed, in whatever way.

ok, this got long again anyway, oh well /ramble

Thanks for coming to my TED talk :)

A while ago I enabled Cachy Update from Cachy Hello when I stopped using Octopi. But now I want to use Shelly. I don't want two system tray items or notifications for updates. If I go into Cachy Hello and toggle off Cachy Update, it goes away... until I reboot. What is the proper way to disable it again?

Hi everyone, I'm running into a frustrating issue with Sunshine/Moonlight on CachyOS that started a few months ago after system updates. Looking for ideas.

Setup:

• CachyOS, KDE Plasma 6.6.5 Wayland
• Ryzen 7800X3D + RX 7800 XT (RADV)
• NIC: Aquantia AQC113 10G (enp7s0), wired
• Network: TP-Link Deco X50+X20 in AP mode, firmware 1.8.0
• Clients tested: Steam Deck (Moonlight Flatpak) + Android (Moonlight) - same issue on both
• Sunshine 2026.516.143833, also tested Polaris fork

Symptoms:

• CLIENT CONNECTED in Sunshine logs, then DISCONNECTED after ~12 seconds
• Moonlight shows "No video received from host"
• Worked perfectly until February 2026
• Steam Remote Play works flawlessly on the same setup

What I've tested:

• All UFW ports open (47984/47989/47990/48010 TCP, 47998:48000/48002 UDP)
• Reduced NIC speed to 1Gbps with ethtool (Sunshine docs suggestion for fast host/slow client)
• MTU 1400 instead of 1500
• Disabled Fast Roaming on Deco
• Forced non-DFS 5GHz channel
• Switched between Deco "Ultra Fast" and "Stable" modes
• VAAPI and Vulkan encoders (both detected)
• Reset xdg-desktop-portal config

Key observations (tcpdump):

• Sunshine sends UDP packets of 15488 bytes on port 47998 → marked "bad length 15488 > 1408"
• Steam Remote Play sends packets <900 bytes → works
• wayland-info | grep zkde_screencast returns empty
• plasma-xdg-desktop-portal-kde logs: MegaAuth: Failed to lookup permissions: "No entry for remote-desktop" and Only stream input

Question: Did anyone else experience this regression after Plasma 6.6 update? Is the screencast portal issue related to the video stream failure, or is it a separate UDP/network issue? Any pointers appreciated.

In my /etc/pacman.conf, I see

[cachyos]

SigLevel = Optional TrustAll

Include = /etc/pacman.d/cachyos-mirrorlist

Is this there for everyone? It makes CachyOS packages not require a signature. This seems unusual to me, but let me know!

Thanks in advance! :]

Updated info: I checked on DistroSea, which is a website that lets you try distros in your browser, and that setting appears there too! With everyone saying it isn't there on their install, it seems to me like it might only be set for newer installs? I installed Cachy last Sunday. Why is it set like this?

title, tried everything

Having reaallllyy bad ping spikes while gaming that make it unplayable ill be at 50 then spike to 300 and then back down to 50

Replaced modem and router (Spectrum provided)
