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

Proceed with cloning https://github.com/Nitrux/linux-cachyos-deb

$ git clone https://github.com/Nitrux/linux-cachyos-deb

$  cd linux-cachyos-deb

Script installs all required packages and pops up TUI dialog to configure kernel 6.16.5 and finally proceed with building of debian kernel packages.

$ ./cachy-kernel-deb

Upon build completition
