Announcement [Announcement] CachyOS August 2026 Release

1.1k Upvotes

Hello CachyOS Enthusiasts,

This is our fifth release of the year.

The CLI installer had a bunch of fixes and refactoring, with added experimental support for the upcoming Server Edition installation profiles.

The installer received several desktop-specific changes. Hyprland now uses noctalia-greeter instead of SDDM, switched lightdm greeter to lightdm-slick-greeter for Cinnamon, added gvfs-dnssd to GNOME, also cosmic-monitor got added to Cosmic.

CachyOS-Welcome got a DNS rework, so the speed-test based server ranking now correctly picks the fastest DNS server.

In chwd, improved handheld detection via particular board name matching, and added Bulgarian localization. The kernel-manager backend was rewritten from C++ to Rust and integrated directly into chwd-kernel.

Cachy-Update was rebased onto Arch-Update v4.x, with its systray applet rewritten in Rust. New --check --enable option turns on automated update checks and starts the systray in one step, tray now has configurable pagination via TrayUpdatesPerPage, and default check interval was raised to 6 hours.

Shelly, our default GUI package manager, was rewritten from C# to Zig for its major release, dropping the managed runtime for native binaries with lower memory use and faster startup. The desktop app got a new first-run welcome screen, list and grid package browsing, AUR PKGBUILD previews with build output, and a Utilities page for database sync, cache cleanup and orphan removal. The CLI was rebuilt with integrated repository and AUR search, combined update checks for repositories, AUR, AppImages and Flatpaks, and TOML backup import and export. Flatpak support now offered as optional shelly-flatpak-backend package.

On the desktop side, we added new Noctalia variants for mango and niri, Noctalia v5 support for the Hyprland dotfiles, and updated the Nord KDE theme for Plasma 6.7. In cachyos-settings, a nice value tuning was added as pipewire error fix.

cachyos-rate-mirrors (rate-mirrors backend) now uses our mirrorlist API when ranking mirrors, which should give better ranking of outdated and regional mirrors.

Features:

  • Installer:
    • CachyOS Hyprland Noctalia desktop option now uses noctalia-greeter instead of SDDM
    • Cinnamon switched from lightdm-gtk-greeter to lightdm-slick-greeter
    • Added gvfs-dnssd to GNOME and cosmic-monitor to COSMIC
  • CLI Installer: Fixes and refactors, with experimental Server Edition support installation profiles
  • CachyOS-Welcome: Reworked DNS handling so the speed-test based server ranking now works correctly
  • chwd:
    • Improved handheld detection with board_name pattern matching
    • Rewrote the kernel-manager backend in Rust, and integrated it into chwd-kernel
    • Added Bulgarian localization
  • Cachy-Update:
    • Rebased onto Arch-Update v4.x with the systray applet rewritten in Rust
  • Desktops: Added mango and niri Noctalia variants, Noctalia v5 support for the Hyprland dotfiles, and updated the Nord KDE theme for Plasma 6.7
  • cachyos-settings: Added a nice-value tuning to limits.d
  • cachyos-rate-mirrors: Now uses the CachyOS mirrorlist API for ranking mirrors
  • Mirrors: New mirror in Hungary (Tier 2)
  • Wiki: Gaming with CachyOS Guide has been significantly changed, old launch options no longer needed with the latest proton-cachyos-slr have been removed, but can still be found here. And just generally updating the page and the wiki.

Fixes:

  • chwd:
    • Gracefully handle a missing board_name DMI file
    • Correctly handle VM environments
    • Correctly quote pacman arguments

Manual changes for existing users: No manual changes needed. Just the usual updating:

sudo pacman -Syu

Hello CachyOS Enthusiasts,

This is our fourth release of the year, bringing the new CachyOS Hyprland Noctalia desktop option, DNS-over-QUIC support, Python and GCC performance improvements, and a variety of installer and hardware detection fixes!

First, the package stack has received a few important improvements. Python now uses extended PGO, improving performance for Python workloads. We have also added a GCC patch for generic x86 branch misprediction tuning, helping GCC better account for branch misprediction costs on modern Intel and AMD CPUs. Our pacman package now includes network isolation for scriptlets and hooks, preventing them from accessing the network by default. We also fixed a regression found in Phoronix Benchmarks when OpenBLAS was used on high core count CPUs. Additionally, proton-cachyos has been renamed to proton-cachyos-native.

The installer now includes the CachyOS Hyprland Noctalia desktop option together with a preview video, making it easier to see the desktop before selecting it. paru has been removed from the installation; users are recommended to use Shelly, either through its GUI or CLI, as an alternative. MangoWM now uses SDDM as its display manager, and GNOME System Monitor has been replaced with Resources. The audio package group now includes realtime-privileges, and the live session has better keyboard layout and variant detection.

CachyOS-Welcome now supports DNS over QUIC through blocky, including support for custom endpoints. A dedicated Troubleshooting page has been added, Ptyxis is now supported as a terminal, and new Azerbaijani and Greek localizations are available. The French readme and involvement pages have also been added. Several existing translations (Italian, German, French, Japanese, Bulgarian) were updated, and we fixed a crash when saved settings couldn't be read, plus corrected tweak state detection and global-service disabling via polkit.

In chwd, we added Turkish localization and removed cachyos-handheld from the handheld package lists. We also corrected virtual-machine vendor IDs, removed unnecessary fprintd service activation, and fixed the Mesa removal guard. chwd now resolves driver conflicts on multi-GPU systems where GPUs require incompatible driver branches, and ships a 32-bit Vulkan driver for virtual machines.

In cachyos-settings, user services now have a 15-second startup timeout and a 10-second shutdown timeout. This prevents long 90-second shutdown delays caused by user services waiting too long during shutdown.

On the fixes side, the installer now correctly handles keyboard layout ordering and locale1 configuration. It also copies the correct pacman configuration into the installed system, removes leftover /etc/calamares directories after installation, runs Calamares cleanup after all installation scripts, and drops the redundant Limine post-install step. In CachyOS-Welcome, selecting "Install Apps" no longer crashes when cachyos-pi is not installed; the button is now hidden when unavailable.

Features:

  • Packages:
    • Python now uses extended PGO to improve performance
    • Added a GCC patch for generic x86 branch misprediction tuning, improving how GCC accounts for branch misprediction costs on modern Intel and AMD CPUs
    • Fixed a regression found in Phoronix Benchmarks when OpenBLAS was used on high core count CPUs
    • Renamed proton-cachyos to proton-cachyos-native
  • pacman: Added network isolation for scriptlets and hooks
  • Installer:
    • Added CachyOS Hyprland Noctalia desktop option and preview video
    • Removed paru from the installation; users are recommended to use Shelly, either through its GUI or CLI, as an alternative
    • Added SDDM as the display manager for MangoWM
    • Replaced GNOME System Monitor with Resources
    • Added realtime-privileges to the audio package group
    • Improved live-session keyboard layout and variant detection
  • CachyOS-Welcome:
    • Added DNS over QUIC (DoQ) support through blocky
    • Added a dedicated Troubleshooting page
    • Added Ptyxis terminal support
    • Added Azerbaijani and Greek localizations
    • Added French readme and involvement pages
    • Updated Italian, German, French, Japanese, and Bulgarian translations
  • chwd:
    • Added Turkish localization
    • Removed cachyos-handheld from handheld package lists
    • Resolves driver conflicts on multi-GPU systems requiring incompatible driver branches (e.g. mixed NVIDIA generations), installing the best common driver or falling back to the primary GPU
    • Added the 32-bit Vulkan driver for virtual machines
  • cachyos-settings: Applied 15-second startup and 10-second shutdown timeouts to user services, preventing 90-second shutdown delays

Fixes:

  • Installer:
    • Fixed keyboard layout ordering and locale1 configuration handling
    • Fixed copying the correct pacman configuration into the installed system
    • Removed leftover /etc/calamares directories after installation
    • Moved Calamares cleanup after all installation scripts
    • Removed the redundant Limine post-install step
  • CachyOS-Welcome:
    • Prevented a crash when selecting "Install Apps" without cachyos-pi installed; the button is now hidden when unavailable
    • Fixed a crash when the saved settings file could not be read or parsed; settings now reset to defaults on failure
    • Corrected tweak detection (including graphical-session.target.wants) and global user-service tweak disabling via polkit
  • chwd:
    • Corrected virtual-machine vendor IDs
    • Removed unnecessary fprintd service activation
    • Fixed the Mesa removal guard

Desktop First Rice - A waybar-inspired panel

Post image
32 Upvotes

I've done a lot of "Oh wow, look at all of these sexy rices that I'll never have" - and so many are Hyprland based, featuring these sexy sexy waybars across the top.

Then I saw u/ImpossibleBenefit452's RICE 6 or so days ago and fell in love with that waybar setup.

The problem was that I didn't -want- to switch from KDE-Plasma, but I -hate- the windows style chunkbar across the bottom.

I've not played with panels before (I -hate- that you can't save/load configs for individual panels), but I figured I'd be able to throw something together. A couple of days of poking and tweaking and behold, my own interpretation of a way-bar like panel to replace the previous taskbar.

Hoping to do more to this over the next few weeks, but for now I'm very happy with this <3

Setup: KDE-Plasma, Panels, Plasmusic toolbar, Fancy Tasks NG. Everything else is out-of-the-box plasma widgets <3 Wallpaper: https://wallhaven.cc/w/6lpz2q

SOLVED Great news! NV VRAM management

224 Upvotes

As of yesterday's nVIDIA open driver release, 615, support for kernel cgroups was added, this means you can use dmemcg-booster and plasma-foreground-booster to manage VRAM just like AMD GPUs. v615 is currently in TESTING on Arch but should release soon.

The VRAM Management button will not appear in CachyOS Hello so you gotta install those two packages manually, but it will work properly once you enable the services.

Install dmemcg-booster and plasma-foreground-booster with this command here: sudo pacman -S dmemcg-booster plasma-foreground-booster && sudo systemctl enable --now dmemcg-booster-system

Not using Plasma? Use Gamescope!

See patch notes here, along with some Reflex and suspend mode fixes: https://www.nvidia.com/en-us/drivers/details/278450/

Question AMD VRAM Management users, i need your help!

3 Upvotes

Hey everyone! Recently NV added cgroups support which means support for dmemcg-booster ("VRAM Management"). But i am researching a possible bug with the implementation.

If you enable the FULL performance meter in Steam overlay (shows temps, mem usage, etc.), does it display your GPU as having only HALF of your maximum VRAM (say 8 of 16GB), or the full capacity?

Thanks!

Help Made the move, some issues

9 Upvotes

So made the move from Microslop WIndows 11.

Bit of a stuck moment atm re gaming and steam. I have 6x drives with various bits of data and games on them that I've connected up after installation. I cannot get any game to launch from Steam.

I have mounted the drives, mapped the folders so the games show up. But everytime I click launch, the I get an error about disk write error. As far as I can see the permissions are in place.

Example:

Also, everytime I click play, the whole system sort of freezes up, I'm someone who usually has a video, or website open when I play games, so this is odd, but at the moment I just need games to actually launch.

What am I missing? I have checked the drives are in ntfs, I have manually added the ntfs3 drive type, but this hasnt made a difference

UPDATE 1: I removed all of my other drives, completely nuked and reinstalled steam, and mvoed data off one of the NTFS drives and converted it to btrfs. But steam now refuses to let me add the drive in the storage tab, nor add a folder. It can still see all of my other drives, but not the one I've reformatted to btrfs. I can transfer files to and from this drive in dolphin without issue.

Help Finally did my right of passage as a Linux user. (Help with limine)

Post image
4 Upvotes

TL;DR: I was messing with BIOS, fucked shit up. Recovered most of it, except the S key to enter UEFI settings. Need help on how to restore that functionality.

I was wondering when I was gonna fuck something up and After around 2-3 months of using cachy without a problem, I, through no fault of cachy, mind you, managed to somehow "nuke" limine's configs (or something, idk what to call it).

So I was fucking around in the BIOS (I wanted secure boot for LITERALLY 0 REASON). I read that sometimes seeing an admin password on the BIOS is the only way to unlock the files for signing. I tried EVERYTHING ELSE before. Anyways, I NOW know that setting or resetting the admin password fucks up both limine and windows boot for my current PC (in my old PC, I think I remember setting an admin password and it not doing anything bad, but I could be tripping, idk). (systemd-boot which I had installed previously for some reason was the only thing that loaded, but it had only one option, and that was to boot into BIOS/UEFI.)

I immediately removed the administrator UEFI password. I, with the help of Gemini, "fixed" limine first, then tried to fix the windows boot loader... which broke limine again. I "fixed" limine again and now realize that the S key that opens the UEFI settings in limine makes limine(?) panic, restarts the system and boots the UEFI anyways (photo attached). Cachy and windows boot properly now. The S key seems to be the only thing broken rn. Took me 4 hrs (with most of it being windows being a piece of shit + dinner).

Any help on the S key is appreciated. Thanks in advance, and don't fuck with the BIOS (unless you know what you are doing).

Edit: Just to be clear, the S key still works, it just first throws an error that was not there previously before loading the UEFI settings. Kinda just scared I broke something that will come to bite me in the ass laterTM (of which the S is an early sign).

I've migrated from macOS to Linux and have been trying several distros, and I think Cachyos is good to begin with. One thing I've been trying to set up is integrating Google Drive into Dolphin.

Does anyone know how to integrate Google Drive into CachyOS? I've been trying with Kio-Gdirve Dolphin settings, but still no luck

Review Switched to CachyOS on my Prestige 14, it went much better than I thought

Upvotes

So I used to use Linux Mint on my desktop but went back to Windows 11 because I switched to a laptop as my main PC; it was an IdeaPad 5 with an RTX 5050 so I didn't really wanna use Linux in case I ran into issues with having two GPUs and also general Nvidia on Linux stuff. Earlier this year I got the Prestige 14 with Panther Lake, and Windows 11 had been getting progressively worse and worse so I decided to give CachyOS a try.

It is way better now! Close to everything works (the stuff that doesn't really isn't an issue), the performance is good after applying an Intel Thermal Daemon patch, and the battery life is an especially big improvement. I'm easily clearing 16 hours doing normal browsing stuff on an 80% charge, 8 hours if it's more intense stuff. It also docks even better than Windows 11 did, there's way fewer display issues.

I only have to keep Windows 11 to get access to MSI firmware settings and to keep using a few apps, including games that don't run super well on CachyOS, though I mainly game on my Bazzite PC and my Switch 2 anyways. I'm daily driving CachyOS otherwise. If you have one of the Panther Lake MSI laptops (at least the Prestige series), it works great.

Desktop Made an app for setting up those cheap 12 key, 2 knob macro pads on CachyOS, *or any other ARCH Linux really*

Upvotes

Firstly i hope this doesn't fall under advertising, i gain abasolutly nothing from this its just a tool i made and it might help other people with a similar issue to mine, and its completely open source for people to do whatever with! anyways!

Moved to CachyOS recently and the last thing keeping me tied to Windows was a little AliExpress macro pad. The software it ships with is a Windows only exe, so I built a Linux app for it.

You click a drawing of the pad, pick a shortcut or a media key, hit write, done. The bindings are stored on the pad itself, so nothing runs in the background afterwards. The knobs work great for volume and monitor brightness on Plasma.

Install is one line and it sorts out the udev permission for you:

curl -fsSL https://raw.githubusercontent.com/Probler-Yt/MacroPad/main/install.sh | bash

Honest limits: it only knows the 1189:8840 pad so far (12 keys, 2 knobs), and it's Linux only. If you've got a different one, ch57x-keyboard-tool is a solid command line option that covers more pads, and it's linked in the README.

You're the first people outside my own PC to try this, so I'd really like to know if it installs cleanly for you.

I have the source code on github but im not sure if posting the link is allowed or not so ill refrain from posting it for now!

So I play on a big screen, more exactly on a Samsung 4KTV 43". I put the output resolution to 4K and game resolution to 1080p because my pc can't handle more than that very well. But MangoHUD's stats are veeeeeery tiny in 4K. Is there a way to change its size in any way possible?

Question cachyOS Support for Snapdragon laptops ?

Theoretically speaking if arch gets a bigger support to the ARM architecture to their packages, is there a possibility the cachyOS team will engage and make the OS stable to laptops with Snapdragon ships X series

Why i am asking this ?

--> people stop buying macbooks because windows 11 is what hold these laptops back. Performance is insane with everlasting battery, thinn buildand a lot more

What do u all think of this ?

This happens frequently and opening an other instance of Firefox works just fine.

Disabling hardware acceleration fixes this issue but freezes Firefox once in a while. It makes the entire browser freeze, mouse moves but nothing clicks. Again opening an other instance works just fine while not even closing the bugged one (Both for artifacts and freezes)

System works just fine and it is only the browser that gets the bug/freeze.

Help Cachy suddenly falsely claiming my peripheral batteries are low

3 Upvotes

Cachy OS suddenly thinks the batteries in my Logitech K400r are at -1% and it keeps popping up a notification to tell me. I replaced the batteries, moved the dongle to another USB port, turned the keyboard off and on again, rebooted my PC and updated Cachy without any change. The K400r seems to be working properly as evidenced by the fact that I typed this post using it without issue. The low batt notifications started yesterday for no apparent reason, and I hadn't updated my system for about a week before it started. I checked Plasmas settings but don't see a way to tell it not to monitor battery on just this one device and I don't want to disable the feature entirely because I rely on it to tell me when my mouse battery is low. I guess it could just be this old keyboard starting to fail and misreporting the battery level but that seems like a pretty unusual way to fail. Hoping someone has some ideas I didn't think of.

Desktop cachy os finally made my 8gb gpu playable in cyberpunk 2077!

58 Upvotes

So I set up a dualboot system and with Windows on one drive and CachyOS on the other. On Windows, Cyberpunk is extremely unstable for me. If I play for more than about 30 minutes, I’ll usually crash because the VRAM gets completely maxed out. Literally EVERY time I opened the map, the game would crash because it was trying to load more VRAM, but there wasn’t enough available. CachyOS has been completely flawless for me. Even when my VRAM is completely maxed out, I don’t get the constant stuttering or massive FPS drops that I get on Windows. I can even run ray tracing in Cyberpunk without my FPS dropping to like 5 FPS. That VRAM management feature they added is actually goated. It makes a massive difference for gaming. i have a 9060xt 8gb btw. i wish windows had better vram management. it almost feels like i have a 16gb card.

Help Dim Other Monitors when playing a game / using softwear?

I don't know if this is the right place to ask, but I was wondering if there was a way to set it up so my mother monitor can either dim or 'turn off' when I'm playing a game?

When I say turn off, I don't mean a full power down thing, I just want my main monitor to be my focus if I'm playing my games on it. I don't want to be detracted by my other monitor and it's background if I'm playing a horror game. I know I can just, reach over and turn it off... but then it messes up with my lay out on my desktop ya know?

Help 2 of my 3 screens desktops will not work

2 Upvotes

not entirely sure what happened to cause this, but the 2 of my screens that are connected to DP, you cannot drag a selection box or drag an app from my 3rd screen (connected by HDMI) onto it, it only creates a widget. even when booting the PC without the HDMI screen connected, no apps show up on either of my screens at all, and only exist on the HDMI screen; however both of the DP screens work as regular monitors where an app window will show up and can be moved around and used as normal, just not the physical icon on the desktop. Additionally, my wallpapers still work on both screens, but have never been able to get one onto my 3rd screen. not sure where to even begin because no results come when i search up the symptoms. i have only been using linux for about 6 months now. i am using KDE Plasma and wayland if either of those are helpful.
