Cosmic Beta DE setup performed via native CashyOS 082825 Calamares installer

 Just select Cosmic during initial run of CashyOS 082825 Calamares installer 

and proceed with installation of Cosmic Beta DE utilizing native CachyOS repositories . Finally make sure that Cosmic Beta has been installed in the same way how we may install KDE Plasma 6.4.5 via original Cachyos ISO as of 08282025

We also may install Hyprland with ML4W Dotfiles DEV 2.9.9.3 along with Cosmic Beta DE on CachyOS. Apparently pre-loading  Hyprland virtual instance and performing actions causing trouble for Cosmic creates some shared objects in virtual machine RAM serving in particular the target of normal switching between folders contain desktop wallpapers  and afterwards we may work for a while in Cosmice DE instance preserving ability to manage Cosmic Desktop with no issues visible at first glance .

I have to notice that the only CachyOS provides a straightforward setup of Cosmic Beta DE vs an other clones of Arch Linux . Say Garuda Mokka or Manjaro Linux for instance

Setup Cosmic Beta as dual DE for openSUSE Krypton ( KDE Plasma 6.5 Beta2)

UPDATE as of 10/7/25  

The most recent CachyOS build as of august 28-th of 2025 provides      straightforward Cosmic Beta installation via it's own version of Calamares Installer . At the moment of writing Google AI's report is not complete regarding CachyOS advantiges. Here we go

Done. Cosmic Beta has been deployed via native CachyOS 082825 installer

Now reproduce the hack been tested on Suse Krypton and switch wallpapers folder to another one . 

END

Once again install Hyprland with ML4W Dotfiles DEV 2.9.9.3 along with Cosmic Beta DE. Apparently pre-loading  Hyprland virtual instance and performing actions causing trouble for Cosmic creates some shared objects in virtual machine RAM serving in particular the target of normal switching between folders contain desktop wallpapers  and afterwards we may work for a while in Cosmice DE instance preserving ability to manage Cosmic Desktop with no issues visible at first glance .

Runtime snapshots of Cosmic Beta DE while main instance is running Suse Krypton been rolled forward up to 10/04/25 (KDE Plasma 6.5 Beta2)

Setup dual DE Cosmic Beta and Hyprland with ML4W Dotfiles 2.9.9.3 on top of fedora 43 server ( build as of 09/30/25)

UPDATE as of 10/2/25  

Actually, I was forced to install Hyprland with ML4W Dotfiles  as second DE, otherwise in Cosmic Beta DE switching of folders contain wallpapers didn't work for me. Same behavior of Cosmic DE shows up on any of Arch Linux Clones.

END UPDATE

First we setup F43 Server KVM Guest and issue `sudo dnf5 update` then reboot instance and run

$ sudo dnf install @cosmic-desktop-environment

Then disable cosmic-greeter.service and enable sddm

$ sudo systemctl disable cosmic-greeter.service

$ sudo systemctl enable sddm

Reboot instance and log into Cosmic Beta DE on top of fedora 43 Server via SDDM login prompt

Verify switching to tiling windows mode

To install Hyprland with ML4W Dotfiles DEV 2.9.9.3 follow same instructions as advised in https://lxer.com/module/newswire/view/357587/index.html

Reboot one more time and now select "hyprland" option been added to drop-down menu of SDDM login prompt

Verify basic Hyprland with ML4W with Dotfiles 2.9.9.3 feature     

Snapshot of SDDM login prompt providing switching between instances

Attempt to run Pycharm on Cosmic DE Beta1 as second DE for Arch Linux KDE Plasma 6.4.5

 Setup Cosmic as second DE for KDE Plasma , reboot select COSMIC from drop-down SDDM menu 

$ sudo pacman -S cosmic-session cosmic

$ sudo reboot

It appears that the only way to create new python code file (or any other file ) for particular project requires one or another way of manual intervention.  In particular it may be done via dolphin file manager either via `touch -f NewPytonFile.py` in correspondent directory  

Run 3D plotting python script in floating windows style

Now switch to tiling windows style for current workspace

Switching between floating style windows to tiling style windows mode and vice versa works fine on Cosmic DE. 

By the way, I have to notice that performance of CachyOS instance ( bare metal ) vs native Arch Linux instance on the same box been assembled with Intel Xeon CPU E5-2690 ( Haswell ), 32 GB RAM and WD NVMe SSD is really impressive, moreover some issues which show up in Cosmic Beta as dual DE appear to be gone when basic instance is running CachyOS.

Setup Hyprland with ML4W Dotfiles DEV 2.9.9.3 via Dotfiles Installer on Fedora 43 Beta as second DE.

 Following below is an attempt to setup Hyprland  with ML4W Dotfiles 2.9.9.3 (Stephan Raabe) on Fedora 43 Beta . Several Copr repositories , which may be easily detected via command `dnf5 repolist` , will be automatically activated

First step would be  add the repository using using remote-add and installing  com.ml4w.dotfilesinstaller

$  flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

$  flatpak install com.ml4w.dotfilesinstaller

Next Step would be start of com.ml4w.dotfilesinstaller

$ flatpak run com.ml4w.dotfilesinstaller

Right after start of installer copy the following url into the Dotfiles Installer and start the installation

https://raw.githubusercontent.com/mylinuxforwork/dotfiles/main/hyprland-dotfiles.dotinst

then  click on Download button. When download will be finished copy to clipboard buffer highlighted command in popped up window and run the script

 /home/boris/.var/app/com.ml4w.dotfilesinstaller/data/downloads/com.ml4w.dotfiles/setup/setup.sh

in another tab keeping original process up and running.  All the steps would be exactly the same as described in Attempt to run the most recent version of Dotfiles Installer designed by Stephan Raabe on СachyOS250713.  See   https://lxer.com/module/newswire/view/355632/index.html

Once again build CachyOS Kernel 6.16.5 on Debian 13 Trixie (VENV)

UPDATE as of 09/08/25  Tested on bare metal as well

Zram enabled

 boris@derp-SVC8664:~$ zramctl

NAME       ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT

/dev/zram0 lz4          15.6G   4K   64B   20K         [SWAP]

 END UPDATE

In general we follow https://news.itsfoss.com/cachyos-kernel-builder/

Start with Pre-installation step

$ sudo apt install bpftool

and include /usr/sbin in system $PATH variable.

On Debian Trixie stable vs Testing install libdw-dev and build dependencies for libdw-dev steps are required to succeed with build CachyOS 6.16.5 Kernel on Debian 13

$ sudo apt install libdw-dev

$  sudo apt-get build-dep libdw-dev
