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:...

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.

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....
