Eu usei alguns scripts em cima de xrandr por alguns anos para definir lado a lado e (atualmente) desktops em formato de tee no Arch Linux. Deve ser um trabalho simples adaptar side-by-side.sh às suas necessidades:
#!/bin/sh
eval '\'dirname -- "$0"\'/monitor_resolutions.sh'
expected_monitors=2
if [ "${monitor_count:-0}" -ne "$expected_monitors" ]
then
echo "$0: Expected ${expected_monitors} monitors; found ${monitor_count:-0}." >&2
exit 1
fi
xrandr \
--output "$monitor1_name" \
--mode ${monitor1_width}x${monitor1_height} \
--rotate normal \
--output "$monitor2_name" \
--mode ${monitor2_width}x${monitor2_height} \
--right-of "$monitor1_name" \
--rotate normal
script de ajuda do monitor_resolutions.sh :
#!/bin/sh
#
# NAME
# monitor_resolutions.sh - Variables for monitor resolutions
#
# SYNOPSIS
# eval './monitor_resolutions.sh'
#
# DESCRIPTION
# Prints a set of 'eval'-able variable assignments with monitor name,
# width and height for each monitor plus a monitor count.
#
# EXAMPLES
# eval './monitor_resolutions.sh'
# Assign monitor1_name, monitor1_width, monitor1_height,
# monitor2_name, etc. and monitor_count variables.

Execute side-by-side.sh no seu local .xprofile ou, caso contrário, apenas após começando X, e você deve ser bom para ir.
Essa configuração funcionou com as placas de vídeo AMD e nVidia, usando drivers proprietários e de código aberto. Eu não acho que eu já tentei com Wayland ao invés de X, mas eu suspeito que isso deveria funcionar se o xrandr trabalhar com Wayland.
