Fix "xbacklight no output have properties" on Arch Linux

The Xbacklight no output have properties message can happen if your hardware has poor support or it can’t be detected properly by the xbacklight utility. This might be fixed by using an xbacklight wrapper called acpilight. acpilight can also be used to control the display and keyboard backlight on modern laptops. First, install the acpilight package: sudo pacman -Syu acpilight Add a udev rule to give access to users in the video group, this is needed because users don’t have permissions to alter sys files by default:...

How to install and upgrade packages on Arch Linux

Arch Linux uses a package manager called pacman, as you may know this is pretty standard on any linux distro, however, I’ve seen that not all the people use the same way to install or upgrade packages. The simpler way you can install a package with pacman is: pacman -S package_name But, this will only install the package on your system and nothing else. You may say but that’s what I want basically, but due to the rolling release nature and since partial upgrades are not supported on Arch Linux this might not be the best approach in the long term and could even break your system....

Configure Touchpad options on Xorg after installing i3wm

If you just installed i3 on a laptop and for some reason you can’t tap or the scrolling behavior doesn’t like you, you can update how the touchpad behaves using a xorg config file.

Passing environment variables to GUI apps on i3wm

I started using i3 as my window manager, and at some point started having some issues with env variables on GUI apps. This is because we usually add env variables to the shell config file, in my case the .zshrc file, however, .zshrc will set the env variables only in your shell and not all the apps. So, when setting up a project using git with ssh and a passphrase as authentication (and after doing all the setup for the gnome keyring) I realized that my VSCode wasn’t actually using the keyring and was asking for the ssh passphrase always, however, this wasn’t happening on my shell....
