Setup Hyprland with ML4W Dotfiles 2.9.8.7 on CachyOS 250530 via Pamac-GUI

We start with attempt to install Pamac-GUI on CachyOS 250530. When install of Pamac-GUI succeeded we synchronize instance with AUR and make sure that ml4w-hyprland-git shows up via interface Add/Remove Programs. Next step is building ml4w-hyprland-git utilizing Pamac-GUI. When done reboot and attempt to run ml4w-hyprland-setup .

Detailed protocol of command running ml4w-hyprland-setup and installing flatpack's applications on CachyOS 250530 follows below after first screenshot , which confirms that `sudo pacman -S pamac-gui` succeeded on current release of CachyOS

Solution one task of Boolean Algebra via Python module utilizing **dict(zip([keys],[values]))

The approach of utilizing **dict(zip([keys],[values])) for solving a wide range of tasks in the course of Boolean Algebra for students is known in general . This post is just a demo of flexibility of python programming for a hard to complete similar tasks in the way limited by the framework of exclusively truth tables, even obtained with limited Python programming skills

The logical function F is given by the expression:

A partially filled fragment containing non-repeating rows of the

truth table of function F is given. Determine which column of the

truth table corresponds to each of the variables x, y, z, w

In your answer, write the letters w,x,y,z in the order in which the

columns corresponding to them appear ( first the letter corresponding to the first column; then the letter corresponding to the second column, etc.) . Write the letters in your answer in a row; no separators need to be placed between the letters.

Solution of the problem above

Instead of building truth table for x,y,z,w via nested loop :-

print("x y z w")
for x in range(0,2):
for y in range(0,2):
for z in range(0,2):
for w in range(0,2):
if ((w == y) or (((not x) <= z) and ((not z) <= y))) == 0:
print(x, y, z, w)

and attempt to place x,y,z,w as correct headers of original columns of the table above using Boolean reasoning .

We intend to run python module below

─boris ~/DICTZIP02

╰─ ❯❯ cat djs02-dzen.py

def f(x, y, w, z):

# due to (not(x) -> z) is equivalent (x or z)

# due to (not(z) -> y) is equivalent (z or y)

return (w == y) or ((x or z) and (z or y))

from itertools import *

for a1, a2, a3, a4, a5, a6, a7, a8 in product([0, 1], repeat=8):

t = [(a1,1,1,a2), (a3,a4,1,a5),(1,a6,a7,a8)]

if len(set(t)) == 3:

for p in permutations('xywz'):

if [f(**dict(zip(p, r))) for r in t] == [0, 0, 0]:

print(*p, sep='')

and obtain result in a few minutes

One more time Hyprland Starter and Dotfiles Installer on Fedora 42 KDE Plasma 6.4.1 && WKS

Detailed instructions as of 06.28.25

Installation via Dotfiles Installer (Stephan Raabe) on Fedora 42 Dual DE (Gnome && KDE Plasma)

As of now just straight forward following directions provided by https://github.com/mylinuxforwork/hyprland-starter?tab=readme-ov-file didn't bring me to success . An exact sequence of steps which allowed me to get the work done follows below. I understand that Hyprland Starter would be built for Fedora 42 with no issues by Stephan Raabe some time later. Posting this approach I consider it only as a workaround at the moment , which may be reproduced and verified. I also have to notice that activation behind the scene of repository copr:copr.fedorainfracloud.org:solopas is important for this setup .

$ sudo dnf5 install hyprctl

Setup kgx via Copr Repos according to Google's AI directives

Install and run Dotfiles Installer per Stephan Raabe

$ sudo reboot

Login via ssh to F42 Dual DE instance.

Then run :-

sudo dnf5 install  \
                   unzip \
                      git  \
                    gum \ 
            hyprland \
              waybar  \
      rofi-wayland \ 
                    kitty \
                  dunst \ 
                thunar \
  xdg-desktop-portal-hyprland \
    qt5-qtwayland  \
     qt6-qtwayland \ 
             fastfetch  \
                        jq  \
       brightnessctl \
     wireplumber  \
               wlogout 

$ sudo reboot
$ sudo dnf5 install hyprpaper
$ sudo dnf5 install hyprlock

Login via ssh to F42 Dual DE instance:-

# Update hyprpaper.conf , add line

ipc = true


# Update monitor.conf

monitor = ,1920x1080@144,0x0,1

$ sudo reboot

Now Hyprlnad with ML4W Dotfiles is ready to run switchWallpapers.sh

#!/bin/bash

WALLPAPER_DIRECTORY=~/Pictures/Wallpapers
WALLPAPER=$(find "$WALLPAPER_DIRECTORY" -type f | shuf -n 1)
hyprctl hyprpaper preload "$WALLPAPER"
hyprctl hyprpaper wallpaper "Virtual-1,$WALLPAPER"
sleep 1
hyprctl hyprpaper unload unused

Setup above was tested on Fedora 42 with Dual DE in virtual environment
