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(rate-mirrors backend) now uses our mirrorlist API when ranking mirrors, which should give better ranking of outdated and regional mirrors.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

Announcement [Announcement] CachyOS June 2026 Release

963 Upvotes

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

Question What happens for end users if the CachyOS team suddenly stopped working on it?

155 Upvotes

A lot of people recommend new users (and just in general) to go with the big main distros like Fedora, Arch, Debian, Ubuntu or Mint, because they say "who knows if flavour of the week distros still exists in 5-10 years".

So i asked myself today, what would happen if maintenance for CachyOS just halted completely? Would it be necessary or recommended for most users to reinstall a different distro, or would the updater simply just grab the new packages from vanilla arch repos and everything is just fine?

Help Shelly

10 Upvotes

Ok. This is probably massive skill issue on my part (possibly amplified by progesterone effects and me being tired right now).

I wanna try shelly.

I install it via pacman. Launch the GUI.

I enable AUR

Try to install AUR package (both with the cli command and the GUI)

Failed to download package sources
error: AUR operation failed
error: BuildFailed
:: Transaction failed.

I look in the docs / wiki. Nothing related to that issue.

I look in the github issues, nothing related to that issue.

Try with another AUR helper, It works.

...

I enable appimages.

Open the GUI, select the appimage section.

"Drag and drop appimages here to install"

I drag and drop the appimage. Nothing happens.

I click the "+ install appimage" button, select an appimage file.

error: AppImage operation failed
error: AppImage operation failed
error: AccessDenied
:: Transaction failed.

I try to install it with the cli. Same error.

I look in github issues / discussions. Nothing related to that issue.

I look in the appimage section in the shelly wiki.

It mentions installing appimages through two methods : static url or repository

Says nothing about how to actually use any of these two methods.

Search for github issues / discussions. Nothing related to that issue.

...

I click on "updates" in the GUI

"Impossible to execute shelly check-updates. Check the cli output and retry"

I run "shelly check-updates" in the cli.

It gives a list of installable packages whose name are close to "check-updates"

...

What ? Am I completely stupid ? Is this an elaborate prank ?

Question Can somebody explain why pacman is unaware where it pulled this package from?

Post image
• Upvotes

Edit: the picture was intended to be at the end of the post body, my bad.

Ran the usual sudo pacman -Syu

This one in the logs in interesting:

```

[ALPM] upgraded libcdio-paranoia (10.2+2.0.2-2.1 -> 10.2+2.0.2-3.1)

[ALPM] installed pdfio (1.6.5-1.1)

[ALPM] upgraded libcupsfilters (2.1.1-4.4 -> 2.2.1-2.1)

[ALPM] upgraded libresidfp (1.2.1-1.1 -> 1.2.2-1.1)

```

pdfio is availble on the cachy-repo (extra-v3), but on running pacman-Qi pdfio the source is unknown:

```

pacman -Qi pdfio

Installed From : None

Name : pdfio

Version : 1.6.5-1.1

```

The reason I checked this, is because Shelly claims this to be from the AUR (maybe because the source is not registered or something?)

Is this a bug where the source is not registered? Pacman for sure did not (and cannot) pull this from the AUR.

It is from the extra-v3 repo: <inset picture>

Review Linux Distro Benchmarks v Windows.

Post image
184 Upvotes

Though this might interest some people.

I recently Benchmarked a Lenovo T480 across multiple Linux Distros and Desktop Environments plus Windows 11

Not this is a older 8th Gen intel so the results show bad performance more than a more advanced processor.

I wasn't surprised by the poor Windows performance (a local install without MS account so minimum BG activity) but what did suprise me was how little the Desktop Environments were influencing results in the Linux Benchmarks.

Anyway here they are.

Help Trash is not emptying + 1 more issue.

2 Upvotes

I just switched. I have an ntfs partition. SO I am trying to merge some free space with this partition. So I was taking backup in case something goes wrong. And along the way I kept deleting files. Old ISOs and media files. I get error trash full. And when shift deleting to permanently deleting files it stopped working with unable to delete errors. Emptying trash does not give any error. It just does not do anything.

So I rebooted and the trash was empty. So I started again. Deleting stuff, but again noticed that trash still won't empty. Why is this happening? (nvme: WD BLACK SN770)

Also dolphin does not show my Linux partition as a mounted device. I won't mind it much, but now I have no idea how much space is left in my Linux installation partition.

Help Need Help Getting Audio Configured As A Musician

2 Upvotes

As the title states, I do a lot of work with music production but also for fun as a bedroom guitarist. I want to use a guitar amp simulator plugin of mine while playing along to YouTube, but when I go to do this I only get audio out of the plugin and nothing else will play any sound and YouTube videos won't load properly because of it. I've briefly looked into the stuff with pulse, jack, and pipewire but it all seems very overwhelming with no real guides. Is this possible to do on Linux? Any help would be appreciated.

Question Faugus GUI issues with GOG & Rockstar Launcher

• Upvotes

Any ideas and help are welcome.

Rescently installed GOG via Faugus, but the GUI was chopped and shifted, went back to Heroic for GOG. But today I installed Rockstar Launcher to play RDR2 and the GUI is also shifted.

This white stripe is shifting the launcher downwards and mousehover is also shifted.

Is this normal for Faugus or is this a GUI problem with my installation?
Using default CachyOS with KDE Plasma, no ricing (all AMD HW).

I can't stop spinning uncontrollably when I play any type of FPS or shooter. I can't stop spinning, and clicking both M1 and M2 makes my character spin slightly too, which I don't know why this happens. This happens on most FPS games.

Whenever I try to move my mouse, my character usually looks up and starts spinning.
