# Essential Tweaks to Fedora 34 i3 Spin

(essential for me at least)

1. general system update

   ```

   sudo dnf update

   ```

2. fix 4k display issues (to scale the display by 2X)

   ```

   # install xrandr which is used to change display properties

   sudo dnf install xrandr

    

   # create a shell script to scale the display

   sudo cat > /usr/share/lightdm/display.sh <<EOF

   #!/usr/bin/env sh

   [ -n "$DISPLAY" ] && /usr/bin/xrandr --output eDP --scale 0.5x0.5

   EOF

   sudo chmod +x /usr/share/lightdm/display.sh

    

   # configure lightdm to run the shell script when showing the greeter and when starting a new session

   sudo sed -i '/greeter-setup-script=/ s/.*/greeter-setup-script=\/usr\/share\/lightdm\/display.sh/' /etc/lightdm/lightdm.conf

   sudo sed -i '/session-setup-script=/ s/.*/session-setup-script=\/usr\/share\/lightdm\/display.sh/' /etc/lightdm/lightdm.conf

   ```

3. install `xss-lock` (this is already included in the default i3 config file) to enable auto start of i3lock when the display is locked; and add a keybinding (mod+shift+p - but use a keycode since I am using Dvorak keyboard layout (which maps this to mod+shift+l in Dvorak)) to lock the screen

   ```

   sudo dnf install xss-lock

   echo 'bindcode $mod+Shift+33 exec --no-startup-id loginctl lock-session' >> ~/.config/i3/config

   ```

4. replace urxvt terminal with alacritty (why bother configuring uxrvt to be usable when there are other terminals that work out of the box?).

   ```

   sudo dnf install alacritty

   sudo dnf remove rxvt-unicode

   ```

5. replace dmenu with rofi (using the default config included in the default i3 config file)

   ```

   sudo dnf install rofi

   # comment out the line that exec's dmenu

   sed -i '/exec --no-startup-id dmenu_run/ s/^/# /' ~/.config/i3/config

   # uncomment the line that runs rofi

   sed -i '/rofi -modi-drun/ s/^# //' ~/.config/i3/config

   ```

6. use Hack font instead of monospace for i3 title bars and i3status (it seems Hack is installed by default but I don't really understand how fonts work or how to verify this)

   ```

   sed -i '/^font / s/.*/font pango: Hack Regular 10/' ~/.config/i3/config

   ```

7. configure trackpad natural scrolling and tap to click

   ```

   sudo cat > /etc/X11/xorg.conf.d/40-trackpad.conf <<EOF

   Section "InputClass"

       Identifier "libinput touchpad catchall"

       MatchIsTouchpad "on"

       MatchDevicePath "/dev/input/event*"

       Option "Tapping" "True"

       Option "TappingDrag" "True"

       Option "NaturalScrolling" "True"

       Driver "libinput"

   EndSection

   EOF

   ```
