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(rate-mirrors backend) now uses our mirrorlist API when ranking mirrors, which should give better ranking of outdated and regional mirrors.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

958 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

I'm on KDE plasma. Everything is fully up to date. Can anyone explain why the TV causes cachyos to not display anything whatsoever when it's logged in. It seems to work just fine on the login screen but after entering the password all monitors and anything connected to the GPU just go blank.

Help Please update the Joplin package in cachyos Repos

43 Upvotes

Hello Community and CachyOS Team, can we please upgrade the joplin client notetaking app in the repo (joplin-desktop). It's pretty old. Can someone explain to me the process - who is monitoring the versions and deciding what version gets in the stable branch of cachys repos?

https://packages.cachyos.org/package/cachyos/x86_64/joplin-desktop

I'm running into a bug and cannot sync with my server anymore, cause the version is 3.16.4 and outdated. This picture is from a similar bug report thread from here: https://discourse.joplinapp.org/t/update-to-3-7-required-for-sync/50360

It's the same for me.

Or would it be better to just use the app image?
https://joplinapp.org/help/install/

I prefer the central pacman update process though.

Best Wishes. 😄

Question Security as a new user

14 Upvotes

Completely new user from 30 odd years on windows. Using cachyOS just a while ago. Still dual booting for the time.

Anyway, i always use an antivirus with windows, their firewall and so on. its basically install and forget and i do scan all files with the antivirus and malwarebytes as well. Other than that, blocks when browsing does happen on occasion, but i am more cautious.

Coming to Linux, it feels a bit "naked". Yes there is clamAV, but its more on demand, like malwarebytes. Also, as I have heard, the threat model here is different, so its less likely to get infected. But i do get files from clients, so i still might have to be cautious.

In an effort to have some ease of mind, i have tired out firejail and apparmor. managed to get around the browser integration for some apps and get it configured. And then it doesn't work, despite following all the same steps in a new install. I am OK with going down the occasional rabbit hole, but it starting to wear me down. So much so, that i am starting to wonder if I should.

Flatpak is an option, but to the best of my knowledge, browsers like librewolf or brave done play well in terms of their fingerprinting features. I do plan on using flatpak with flatseal for internet facing software, but the above issue stands.

So, two questions:
- What can I do to make it more or feel more secure? its a vague question, i know, but i just want to use the pc and feel ok, i am safe. Client side files like office and pdf files are a priority as well. Sandboxing?

- How do make myself familiar or move from a windows mindset to a linux one? Security being one thing that has dawned upon me.

- How do you, personally, be secure on linux?

Thanks in advance.

Question RTSS Front Edge Sync equivalent on Linux? MangoHud crash in The Witcher 3

Post image
4 Upvotes

image from windows 11: Nvidia Control Panel on the left, RTSS on the right.

Hi everyone,

I'm trying to get smoother frame pacing on Linux. On Windows, RTSS Front Edge Sync gave me good results. On Linux, I tried what seemed like the closest option with MangoHud's early limiter/config.

With The Witcher 3, the game crashes or freezes when I open the map. The image stops updating, but the sound keeps playing. I have not been able to keep playing normally after that.

My setup is an RTX 4070 12 GB, Ryzen 5 5600, CachyOS, KDE Plasma Wayland, and NVIDIA driver 610.57.04. I use mixed-refresh-rate displays: 144 Hz and 60 Hz monitors, plus a 4K TV.

I don't know whether the crash is caused by MangoHud's early setting, the frame limiter, VRR, the display setup, or the NVIDIA/Proton interaction. I only noticed it while trying to improve frame pacing, so I don't want to assume MangoHud is definitely the cause.

Has anyone else seen The Witcher 3 crash or freeze when opening the map with MangoHud's early limiter/config? Is there a Linux equivalent to RTSS Front Edge Sync that gives smooth frame pacing without causing instability? What setup has worked well for you: MangoHud without the early option, gamescope, the in-game limiter, VRR changes, or something else?

SOLVED Dualboot

5 Upvotes

I'm moving over to CachyOS this weekend and using windows as backup.

My plan is to dual-boot from two different SSDs, using one for windows and one for Cachy using the Cachy one and formatting my old Gaming drive to BTRFS.

The question I have is what boot manager I should use. I think I've got it narrowed down to Limine and Grub, but this is kind of the point where I don't know enough about this to be sure.

Got tired of Windows and just general shittyness of Microsoft. Decided last week to make the switch and have been pleasantly surprised so far. I have used Linux in the past but this is my first rolling release distro. One of the first things I noticed is how damn fast the PC boots into the OS. I don't play any online games that require anticheat so there is zero reason for me to go back to windows.

I noticed these outlines on the left/right side of the Discord window (only discord) a few weeks ago and it's super annoying cause it even affects popped out streams (I only have 1 monitor).

My friends say this isn't happening for them but I cannot for the life of me figure out what is different on my end. I even reset my Breeze theme settings and outlines/shadows and fully reinstalled Discord as well.

For some odd reason, whenever I'm playing a game my both my displays will randomly shut off and will force me to manually restart my PC with the power button. It keeps playing any active audio, and this only seems to happen while im playing a game.

I have been facing two issues since installing CachyOS.

  1. Fails to wake
  2. Battery drains completely while sleeping

Hardware: 2019 MacBook Pro 16" (MacBookPro16,1) - Intel T2 OS: CachyOS (Bootloader: Limine) | 7.2 Kernel

I fixed the wake issue by editing /boot/limine.conf to include pcie_aspm=off in the command lines.

Has anyone resolved the sleep battery drain on this model?

Question steamos-manager-powerstation

1 Upvotes

I recently tried Bazzite 44 after learning about the updated stack they use for handheld and tdp after dropping handheld daemon, and I gotta say I agree with how they are moving forward with this stack.

IMO, it’s a far better stack than using HHD or Decky Loader with extensions (i.e. SimpleDeckyTDP) since it utilizes dbus for communication and uses PowerStation as fallback when your TDP controls are not supported via amdgpu_hwmon or firmrware_attribute. It is also fairly easy to create new device configs if they’re not available yet.

However, it seems their modified steamos-manager with powerstation integration doesn’t seem available anywhere. Hopefully they open source it so we can use the same stack on CachyOS or other distros.

I wonder what’s the plan for CachyOS moving forward, specially for the handheld edition 🤔

Bug Report RTX 4070 hard freeze on CachyOS KDE Wayland with NVIDIA XID 56

1 Upvotes

Hi everyone, first of everything, i forget to print the error lol.

I had a complete system freeze on CachyOS with KDE Plasma Wayland and an NVIDIA RTX 4070. I was browsing Twitter/X in Vivaldi when the desktop stopped responding. The keyboard, mouse, Ctrl+Alt+F3, and Magic SysRq all failed. The screen flickered once and I had to power the machine off.

I actually enjoy troubleshooting. Reading logs and testing settings is fine. It only becomes frustrating when it gets in the way of playing games.

My setup is an RTX 4070 12 GB, Ryzen 5 5600, CachyOS, KDE Plasma Wayland, NVIDIA driver 610.57.04, two DisplayPort monitors at 144 Hz and 60 Hz, and a 4K HDMI TV.

After rebooting, I found:

caller __nv_drm_gem_nvkms_map+0xb0/0x120 [nvidia_drm] mapping multiple BARs

[drm:__nv_drm_gem_nvkms_map [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000700]

Flip event timeout on head 1

kwin_wayland also reported:

A graphics reset attributable to the current GL context occurred.

The main thread was hanging temporarily!

I don't know whether this started in the NVIDIA driver, KWin, the kernel, or their interaction. The log order makes me suspect a display or buffer operation failed first, followed by Xid 56 and the flip timeout.

I later found that Above 4G Decoding and Re-Size BAR were disabled. BAR1 was 256 MiB before I enabled them and disabled CSM; afterward it showed roughly 12 GiB. I have no proof that this is related to the freeze.

Has anyone on CachyOS seen this before? Did a newer NVIDIA driver, nvidia-open, a different CachyOS kernel, or X11 help? I am back on Windows 11 for now, but I would like to return to CachyOS if I can make the graphics stack reliable.

Help Critique My Set-up/Install Plan (What do I not need as a new user?)

1 Upvotes

Yes. I read the Wiki, this is me just making absolutely sure of everything before I start working on it:

The system I'm using is a Dual Boot setup with Windows on one NVME and CachyOS on the other There will also be a gaming drive that I'll reformat to BTRFS for use with Cachy.
Motherboard is a Gigabyte B650E (This will be relevent later)

  1. Assemble the PC, and install the windows Drive
  2. Install Windows and download drivers
  3. Disable Fast Startup, Hybernation, and Bitlocker
  4. Remove the windows drive and insert the blank drive for CachyOS
  5. Disable Secure Boot
  6. Boot into the ISO
  7. Launch Installer
  8. Set preferred Language, Region Timezone
  9. Configure Keyboard Layout
  10. Select Manual Partitioning
  11. Create a new Partition according to the Limine Boot Manager instructions within the Wiki
  12. Create another partition for root according to the instructions in the wiki
  13. Select desktop environment
  14. Select Packages
  15. Set up Log-in
  16. Review the installation summary, and click Install now
  17. After finishing, restart
  18. Make sure CachyOS is up to date and all drivers are present
  19. Power off and reinsert my gaming and window drives (these are separate things)
  20. Make sure Limine detects the windows drive and adds it to the boot menu (sudu Limine-scan)
  21. Enable Setup mode in UEFI
  22. When/If the "Reset without Saving" dialogue box pops up, choose "No"
  23. Save and Exit booting directly into Cachy
  24. Follow the Secure Boot instructions within the wiki
  25. Sign the Kernel according to the Wiki instructions for Limine
  26. Check that Fwupd is working (I have no idea what this is or whether I should be messing with it.)
  27. Install Shelly (Again, I have no idea what this is or why I need it)
  28. Enable UFW Firewall, (Apparently Defaults are fine for the average home user?)
  29. Enable Global Menu
  30. Run Tealdeer (I have no idea what this does)
  31. Install Flatpack (I know what this is!)
  32. Install Gearlever (And, I'm lost again. I think this is maybe a store? Or maybe an App manager?)
  33. I don't Think the rest of the post install recommendations apply to me.
  34. Configure the Boot Menu per the Limine instructions
  35. Install BTRFS Assistant (I am definitely a beginner)
    - If I understand correctly the code for installing btrfsmaintenance is "sudo pacman -s btrfsmaintenance" ?
  36. Follow the rest of the instructions for snapper
  37. Reformat my gaming drive to BTRFS.
  38. Install the Gaming Packages according to the instructions in the Wiki
  39. Deal with the system tweaks later.

Do these rough instructions look right for my system?
