Display Manager with fractional scaling support for X11

---

Introduction

ReScreen is an open-source tool that tries to simplify the per-display fractional scaling problem many users have on Linux inside an X11-Session. You can use the graphical display configurator to configure your display setup to your liking. When you are satisfied with the setup, the configuration is saved and applied to your system. Everytime the connected display configuration changes, ReScreen automatically tries to find a matching profile and if it found one, it gets applied. You can also manually force this behaviour using the command line interface.

Installation

Debian/Ubuntu

1. Download the .deb-File from the Release Page.

2. To install it on your system, use

   $ sudo apt-get install -f <path to the .deb-File>

A package repository for deb packages is in the making 🚧

Arch

1. Download the .pkg.tar.zst-File from the Release Page.
2. To install it on your System, use

   $ sudo pacman -U <path to the .pkg.tar.zst-File>

An easier method for installing this package on Arch is by using the AUR ⬇️

AUR

1. With an AUR-Helper of your choice (I will use yay in this example), install the package using

   $ yay -S rescreen

PIP

1. This will not embed rescreen into your system, only the command line tool gets installed. The GUI is not available as a shortcut in the menu and the screen change watcher does not automatically run in the background.

   You also need to install the required system dependencies on your own, including xrandr, xev, loginctl, whoami and edid-decode

   To install only the command line tools on your system, you can use

   $ pip install rescreen

Command Line Usage

Detect and save the current display configuration

$ rescreen save

Detect the current display configuration, try to find a matching profile and apply it if found

$ rescreen load

Start the Graphical Display Configurator

$ rescreen gui

Start the display change watcher that automatically tries to apply the matching profile

Note: This command needs to be run with superuser-permissions. The preferred way of using the watcher is to have it installed as a systemd-service

(This is done in the bundled packages for the distributions)

$ rescreen watcher
