Napomena, kada koristite dual-boot sa Windows operativnim sistemima, koristite EasyBCD da dodate u Windows boot meni i stavku za Void Linux.

Ako koristite GPT umesto BIOS (dos) particija, onda morate koristiti i SuperGRUBdisk.iso, a ovaj ISO možete dodati u EasyBCD kao ISO stavku (koristite podizanje ISO iz memorije, mnogo je brže, a i SuperGRUBdisk.iso je veoma mali oko 12 MB, a izuzetno koristan).

Void Linux - an incredible linux distro indeed

Void Linux idle RAM usage:

Void Linux idle htop RAM usage = 280 MB:

Void Linux + Firefox +YouTube + htop RAM usage = 688 MB:

Void Linux + FreeTube + htop RAM usage = 532 MB:

Install>

Boot your machine from the install media you created. If you have enough RAM, there is an option on the boot screen to load the entire image into ram, which will take some time but speed up the rest of the install process.

Once the live image has booted, log in as root with password voidlinux and run:

# void-installer

Post-install>

# xbps-install -Su

# xbps-install -S pulseaudio

# xbps-install -S pavucontrol

# xbps-install -S xfce4-pulseaudio-plugin

# xbps-install -S htop

# xbps-install -S xfce4-xkb-plugin

(right click mouse on Panel, +Add Panel, +add Keyboard Layouts), select your flag - keyboard layout and enjoy !

In Settings > Keyboard you can add other keyboard layouts.

Just use SuperGrubDisk.iso to show all partitions and boot Linux partition alongside other Windows partitions.

Alpine Linux i3 installation

The Alpine Linux installation ISO uses root as the default user and an empty password. In order to login, just enter the username root and press return.

Post installation commands:

# apk update

# apk add xf86-video-intel xf86-input-intel xf86-video-fbdev xf86-video-vesa

# apk add terminus-font xrandr

# apk add dbus doas nano

# dbus-uuidgen > /var/lib/dbus/machine-id

# rc-update add dbus

# nano /etc/doas.d/doas.conf

Add the following line and save the file (ctrl+O, crl+X):

permit persist :wheel

# setup-xorg-base

# apk add i3wm i3status xterm firefox-esr geany thunar pulseaudio pavucontrol

# apk add icu-data-full ----►(for non-unicode locales)

# adduser joe

# adduser joe wheel

# addgroup joe input

# addgroup joe video

# adduser joe video

# adduser joe audio

# adduser root video

# adduser root audio

# rc-service dbus start

# rc-update add dbus

# rc-update add udev

$ pulseaudio -k

$ pulseaudio --start

$ pavucontrol

xrandr

xrandr -s 1024x768

$ startx /usr/bin/i3

Press enter for the first time to select Win mod key, when you enter in i3 environment first time.

Important notice: Write on paper file path to i3 config file !

In i3 config just add:

In my case you have for instance file:

/home/joe/.config/i3

In that file just add following lines:

bindsym $mod+Shift+t exec xterm

bindsym $mod+Shift+w exec firefox

bindsym $mod+Shift+d exec geany

bindsym $mod+Shift+f exec thunar

So it works like...

If you want to start terminal press Win+Shift+t,

If you want to start firefox press Win+Shift+w,

If you want to start file manager press Win+Shift+f,

If you want to start text editor press Win+Shift+d,

If you want to close selected window press Win+Shift+d, that is like ALT+F4 (but alt+f4 not working in i3).

If you want to close i3wm, just press Win+Shift+e.

Isn't it sweet ?

Optional part:

~~But nitrogen is not in repositories ?~~

~~# apk add nitrogen~~

add line to /home/joe/.config/i3:
exec --no-startup-id nitrogen --set-auto /path/pic1.jpg --head=0 && nitrogen --set-auto /path/pic2.png --head=1

The Negative aspects of Alpine Linux are:

1.) Repository has not "nitrogen".

2.) ImageApp not working.

Instead of ImageApp you can use better solution = it is FLATPAK.

FLATPAK can install almost everything.

Lightdm exist in repositories, that is awesome :)

And last settings for loging Lightdm stuff:

# apk add lightdm lightdm-gtk-greeter

# rc-update add lightdm

# echo "exec startx /usr/bin/i3" >> ~/.xinitrc

# rc-service lightdm start

Select user joe from lightdm form and enter proper user password for joe !

-------------------------------------------------

That is i3wm installation, if you like rich XFCE try this:

Fedora xfce idle RAM usage ~ 600 MB

My suggestion to you, avoid Fedora if you can !

Beware: ☺► FreeTube ImageApp and RPM install of FreeTube "working", but reproduction of video and audio not working on Fedora.

Fedora is not good and easy like some Debian based distros. Some apps not working, panel bar sometimes flickering!

Please compare 576MB of idle RAM usage in Fedora and 280MB idle RAM usage in Void Linux !

Both distros use XFCE, and what a difference !

Fedora is overbloated Linux distro after all.

ARCH LINUX for beginners

XFCE instalacija na ARCH Linuxu:

Evo uputstva na engleskom, koji verovatno svi razumete. Uputstvo sam napravio na engleskom da što veći broj ljudi razume koliko je u stvari instalacija Arch Linux-a jednostavna, zaboravite na Arch Wiki.

First load Arch Linux, then start following command:

archinstall

You must have at least 3 partitions, like:

/root 100G ◄----ext4

/boot * 512M ◄----ext4

/swap 4G ◄-----linux swap

When you create partition be sure to select "dos" option at first.

Warning, partition "/boot" must be set as [boot], if everything is fine then you must see * asterisk near boot partition.

If you not set /boot partition as boot, grub will not working properly.

After creating of partitions, you must to select proper partition and confirm that.

After "installing applications", you must to rotate down the mouse wheel to continue with installer, do not leave or close installer until all stuff was installed !

During installation process you must to choose "pulseaudio", that is very important !

After successful completion of "archinstall" script and reboot, you must to do post-installation steps:

sudo pacman -Syyu

sudo pacman -S nano doas

-----------------------------------

nano /etc/doas.d/doas.conf

Add the following line and save the file (ctrl+O, Enter, ctrl+X):

permit persist :wheel

-----------------------------------

sudo pacman -S elogind polkit-elogind

sudo pacman -S xorg xfce4 xfce4-terminal xfce4-screensaver lightdm-gtk-greeter dbus

sudo pacman -S xfce4-pulseaudio-plugin

sudo pacman -S pavucontrol firefox

sudo pacman -S xfce4-xkb-plugin

reboot

Kada instalirate xfce4-xkb-plugin, onda možete šaltovati jezike, ako ste prethodno u Settings - Keyboard - Layouts namestili layoute za engleski, srpsku cirilicu i latinicu.

Pre uportebe treba da dodate Keyboard Layout Switcher u Panel, desni taster miša na Panel, pa add to Panel.

Nakon toga je vreme da podesimo splash formu za logovanje na sistem ili "Lightdm":

Tu se unosi username i password pre ulaska u desktop...

Loging settings - Lightdm settings:

---------------------------------

sudo nano /etc/lightdm/lightdm.conf

just uncomment, remove # at line:

greeter-session=lightdm-gtk-greeter

make sure that =lightdm-gtk-greeter

after change, just press (ctrl+O, Enter, ctrl+X) to save it.

------------------------------

lightdm --test-mode --debug

Very important command:

sudo systemctl enable lightdm -f

Following command is not necesary:

lightdm --test-mode --debug

Ovde je ukratko objašnjen ceo postupak instalacije Arch linux-a, kao što možete primetiti uopšte nije tako komplikovano.

Sada priznajte, da li ste na nekom drugom web sajtu videli ovako jednostavan postupak, čak i na ArchWiki je ultra komplikovano i konfuzno objašnjeno kako instalirati Arch.

Evo dokaz da Arch instalacija može biti ultra jednostavna.

Koristio sam XFCE jer je najsličniji Windows-u koji koristi većina ne-Linux korisnika, odnosno, običnih korisnika kompjutera.

Imate sve od zvuka, mreže, firefox, sve kompletno i funkcioniše, sve ostalo možete sami instalirati koristeći pacman -S (naziv-aplikacije).

Arch Linux RAM usage in XFCE:

Arch + xfce + firefox + youtube = 1.03 GB

Arch + xfce + freetube = 734 MB

Anydesk is available for Arch Linux users. However, there are no download instructions on the Anydesk website. Instead, Arch Linux users will need to rely on the Arch Linux AUR.

To start the installation, you will need to install the Trizen AUR helper. Install Trizen with the commands below.

sudo pacman -S git base-devel

git clone https://github.com/trizen/trizen

cd trizen

makepkg -sri

After installing the Trizen AUR helper, you will be able to install Anydesk on Arch Linux with the following command.

trizen -S anydesk-bin
