Using Custom DNS

sudo systemctl enable --now systemd-resolved

• After enabling systemd-resolved, follow the instructions of custom DNS you want to use. My suggestions are listed below:
• Cloudflare DNS
  • The fastest but weak when it comes to privacy.
• NextDNS
  • The second fastest after Cloudflare but really good when it comes to privacy.
• Mullvad DNS
  • Not bad in terms of speed but the best when it comes to privacy.

Gaming

I have a separate guide about gaming on Linux. You can check the guide from here.

Laptops

I have a separate optimization guide for laptops but mainly for Thinkpads. You can check the guide from here.

Use Android on Linux

I have a separate guide about using Android on Linux. You can check the guide from here.

Disabling NetworkManager-wait-online.service

For a faster boot time, disable NetworkManager-wait-online.service:

sudo systemctl disable NetworkManager-wait-online.service

Terminal Configuration

Fish Configuration

If you would like your terminal to predict what you are going to type, I suggest that you use Fish for your terminal.

sudo pacman -S fish

chsh -s /usr/bin/fish # you should reboot after running the command

Note

• If terminal tells you that the process has failed, try chsh -s /bin/fish instead.
• Additionally, if you would like to see fastfetch every time you launch terminal, you should execute the commands below:

  function fish_greeting
  fastfetch
  end

funcsave fish_greeting

fastfetch Configuration

Warning

• Fastfetch's default theme is usually useful but if you would like to try my fastfetch theme, you should execute the commands below.
• The picture below is an example of how my fastfetch theme looks like. If you did not like it, please skip this step.

sudo mkdir ~/.config/fastfetch/ && sudo nano ~/.config/fastfetch/config.jsonc
