Usage

Prerequisites

Install the Xorg dummy driver for your distribution:

# Debian/Ubuntu
sudo apt update && sudo apt install xserver-xorg-video-dummy

# Arch/Manjaro
sudo pacman -S xf86-video-dummy

# RHEL/Fedora
sudo dnf install xorg-x11-drv-dummy

Configuration

Works for me on Manjaro Linux.

1. Backup and remove the current config:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.back
sudo rm /etc/X11/xorg.conf

2. Prepare the configuration directory (if it doesn't exist):

sudo mkdir -p /etc/X11/xorg.conf.d/

3. Create and fill the new config file from this Gist:

sudo nano /etc/X11/xorg.conf.d/99-rustdesk.conf

4. Restart your display manager to apply the new config (or reboot):

sudo systemctl restart display-manager
