Hyprland on Ubuntu 24.04

Hyprland is not available by default on Ubuntu 24.04 so instead we can utilize the Nix package manager and Home Manager.

Nix

The benefit of the Nix package manager compared to others in this case is that the package and dependencies of Nix packages is immutable and self contained. This means that the entire setup is contained to a separate /nix path. Changes to Nix packages does not break Ubuntu and changes to Ubuntu does not break Nix packages.

You should be greated by the ClickHouse prompt

ClickHouse client version 21.12.3.32 (official build).

Background

The Swerty keyboard layout is created by Johan E. Gustafsson and hosted on http://johanegustafsson.net/projects/swerty/

Swerty is released under the MIT Licence.

Since I spend a lot of time getting the right alt-gr key to work I decided to share back my fixes.

How to install Samsung ML-2160 in Arch Linux

In order to use a USB connected Sasmung ML-2160 printer in Arch Linux you will need to first install the correct drivers. For this perticular printer the drivers are included in the samsung-unified-printer AUR package.

If you know what you are doing I recommend installing it using a AUR helper such as yay.
