Arch Linux — Powered by Dag

What about having a fully working Arch Installation - on your machine? Well, it always has been my dream since the first Arch installation ever.

As I told you here, I installed Arch on a specific computer, so I have carefully chose my packages.

These packages are in addition to the packages I’ve already installed in that guide:

intel-ucode nvidia vlc firefox discord telegram-desktop alsa thunar gcc htop i3 lxappearance ntfs-3g wget picom powertop redshift git xdg-user-dirs xclip maim tree xorg neofetch base-devel

Issues I had once I installed Arch Linux:

  • can’t change background
  • no aur helper
  • no common programs installed
  • no polybar setup
  • audio control not available by keyboard
  • brightness control not available by keyboard
  • no trasparent windows
  • “open containing folder” button doesn’t properly work in Firefox
  • autoconnect to wifi
  • wifi powersaving off
  • Enable lightdm and fix it because it doesn’t work
  • no wakeup after sleep
  • autostart things — redshift in my case
  • screenshot pasted into clipboard
  • multiple keyboard layout: switch between one layout and another one by pressing CTRL+SPACE
  • poweroff commands don’t work
  • no speakers and no microphone
  • cant open zip file and unzip them
  • battery drain

Can’t change background

This is an easy one, just put this in your console:

nitrogen <wallpaper folder>

It will open a window which will prompt you image picker.

In your i3 config place this line:

exec –no-startup-id nitrogen –restore

No aur helper

sudo git clone [https://aur.archlinux.org/yay-git.git](https://aur.archlinux.org/yay-git.git)
sudo chown -R user:user yay-git
cd yay-git & makepkg -si

No common aur programs installed

In my case they are polybar, vscodium-bin and intellij-idea-ultimate-edition

yay -S polybar vscodium-bin intellij-idea-ultimate-edition p7zip-gui siji

No polybar set up

Comment the lines related to bar in your i3 file and add this line:

exec_always — no-startup-id $HOME/.config/polybar/launch.sh

Create xdg user dirs by giving xdg-user-dirs-update

Now polybar in order to work needs two files: config and launch.sh

cp /usr/share/doc/polybar/config .config/polybar/config

Change your “example” to “bar”.

Create into ./config/polybar/ a file named launch.sh , give:

chmod 755 ./config/polybar/launch.sh

Now it’s time to fill it by copy-pasting this:

#!/bin/bash

# Terminate already running bar instances  
killall -q polybar

# Wait until the processes have been shut down  
while pgrep -u $UID -x polybar >/dev/null; do sleep 1; done

# Launch Polybar, using default config location ~/.config/polybar/co>  
polybar bar &

echo “Polybar launched…”

Audio control not available by keyboard

In your i3 config file you need to comment the lines related to bindsym XF86AudioRaiseVolume , bindsym XF86AudioLowerVolume and bindsym XF86AudioMute.

NOTE: I installed sof-firmware that’s why I need to specify the -c 1 option.

It is needed to overwrite them with the ones we are adding:

Audio control

bindsym XF86AudioRaiseVolume exec amixer -q -c 1 sset Master 1+ unmute  
bindsym XF86AudioLowerVolume exec amixer -q -c 1 sset Master 1- unmute  
bindsym XF86AudioMute exec amixer -q -c 1 sset Speaker toggle & amixer -q -c 1 sset Master toggle

Brightness control not available by keyboard

Add this in i3 config file:

Backlight Control — requires brightnessctl and nvidia

bindsym XF86MonBrightnessUp exec xbacklight -inc 5 # increase screen brightness
bindsym XF86MonBrightnessDown exec xbacklight -dec 5 # decrease screen brightness

No trasparent windows

After having installed picom, copy the default conf file:

sudo cp /etc/xdg/picom.conf .config/picom.conf

Fix its permissions:

sudo chown user:user .config/picom.conf

Then edit with nano by replacing vsync = true; with vsync = false

vsync = false; in the .config/picom.conf

Add this in i3 config file:

# Window Compositor  
exec_always picom -f

Add this to .config/picom.conf

inactive-opacity = 0.75;  
active-opacity = 1;  
frame-opacity = 1.00;

Open containing folder button doesn’t properly work in Firefox

When you click on Firefox “open containing folder” button after a file it didn’t work

xdg-mime default thunar.desktop inode/directory

Autoconnect to wifi

In the terminal:

cp /etc/netctl/examples/wireless-wpa /etc/netctl/somedescriptivename
  • Edit your new config at /etc/netctl/somedescriptivename to fit your setup.
    Remember to set priority or it won’t work
  • Enable the netctl-auto service for your wireless adapter.
systemctl enable netctl-auto@<device>.service

To list your interfaces (install iw first):

iw dev | awk '$1=="Interface"{print $2}'

Wifi powersaving off:

sudo nano /etc/udev/rules.d/81-wifi-powersave.rules

Inside it:

ACTION==”add”, SUBSYSTEM==”net”, KERNEL==”wl*”, RUN+=”/usr/bin/iw dev wlp0s20f3 set power_save off”

Enable lightdm (and fix it because it will not work)

Uncomment in lightdm greeter-session and replace with

[Seat:*]  
greeter-session=lightdm-gtk-greeter

FIX: Add this to your /etc/lightdm/lightdm.conf in the [LightDM] section:

   logind-check-graphical=true

Then:

systemctl enable lightdm

No wakeup after sleep

sudo nano /etc/systemd/system/suspend@.service

Write this inside:

[Unit]  
Description=User suspend actions  
Before=sleep.target  
  
[Service]  
User=%I  
Type=forking  
Environment=DISPLAY=:0  
ExecStartPre= -/usr/bin/pkill -u %u unison ; /usr/local/bin/music.sh stop  
ExecStart=/usr/bin/sflock  
ExecStartPost=/usr/bin/sleep 1  
  
[Install]  
WantedBy=sleep.target

Now, type

sudo nano /etc/systemd/system/resume@.service

Write this

[Unit]  
Description=User resume actions  
After=suspend.target  
  
[Service]  
User=%I  
Type=simple  
ExecStart=/usr/local/bin/ssh-connect.sh  
  
[Install]  
WantedBy=suspend.target

And finally

systemctl enable suspend@  
systemctl enable resume@

Autostart things with i3

Add them to i3 config file preceded by exec or exec_always.

Useful things I put in mine:

exec redshift -l 41.90:12.49

Screenshot

Add this to i3 config file (requires maim and xclip):

bindsym Ctrl+Print exec --no-startup-id maim | xclip -selection clipboard -t image/pngbindsym Ctrl+$mod+Print exec --no-startup-id maim --window $(xdotool getactivewindow) | xclip -selection clipboard -t image/pngbindsym Ctrl+Shift+Print exec --no-startup-id maim --select | xclip -selection clipboard -t image/png

Multiple key layout (switching from one keyboard to another one with WIN+Space)

Copy-paste this into terminal

localectl set-x11-keymap us,it pc105 qwerty grp:win_space_toggle

Poweroff commands doesn’t work

Become superuser:

sudo su

Override visudo editor:

export EDITOR=nano

Type visudo then add this at the end of the file:

_user_ _hostname_ =NOPASSWD: /usr/bin/systemctl poweroff,/usr/bin/systemctl halt,/usr/bin/systemctl reboot, /usr/bin/systemctl suspend

And in your .bashrc:

alias reboot="sudo systemctl reboot"  
alias poweroff="sudo systemctl poweroff"  
alias halt="sudo systemctl halt"  
alias suspend="sudo systemctl suspend"

No speakers — no microphone

It works for me:

echo "options snd-hda-intel model=generic" >> /etc/modprobe.d/alsa-base.conf  
echo "options snd-hda-intel enable_msi=1" >> /etc/modprobe.d/modprobe.conf

Let’s install sof-firmware:

sudo pacman -S sof-firmware

Can’t open zip files and unzip them

sudo pacman -S p7zip

then from your favorite aur manager:

yay -S p7zip-gui

Battery drain

Install TLP

sudo pacman -S tlp

Let’s autostart this service

sudo systemctl enable tlp.service`

Cool custom theme

Download it first:

wget [https://github.com/Roboron3042/Cyberpunk-Neon/raw/master/gtk/materia-cyberpunk-neon.tar.gz](https://github.com/Roboron3042/Cyberpunk-Neon/raw/master/gtk/materia-cyberpunk-neon.tar.gz) -O materia.tar.gz

Let’s un-tar it:

tar xzf yourfavouritetheme-cyberpunk-neon.tar.gz -C ~/.themes/

Open lxappearance and select it from your theme list
