I'm using rofi (wiki), together with a customized rust program driving the interactive menu, displayed by rofi.

• I wrote this script using the example from i3_switch_workspace.sh
• It is relatively straight-forward to include other shortcuts to configure the display
• rofi has various themes, I included a screenshot of the default theme

#!/bin/sh

# Configure names of external and internal displays
EXTERNAL="HDMI-A-1"
INTERNAL="eDP-1"

function show() {
  way-displays --delete DISABLED "$1" > /dev/null
}

function hide() {
  way-displays -s DISABLED "$1" > /dev/null
}

OPT_INTERNAL="Internal display"
OPT_EXTERNAL="External display"
OPT_BOTH="Both displays"

function menu() {
  echo "${OPT_INTERNAL}"
  echo "${OPT_EXTERNAL}"
  echo "${OPT_BOTH}"
}

OPTION=$( (menu)  | rofi -dmenu -p "Configure displays")

# Invoke way-displays. Only hide a display if showing the other display
# succeeded. This reduces the chances to end up with both displays turned off,
# which is typically rather inconvenient.
if [ "${OPTION}" == "${OPT_INTERNAL}" ]
then
  show "${INTERNAL}" && hide "${EXTERNAL}"
elif [ "${OPTION}" == "${OPT_EXTERNAL}" ]
then
  show "${EXTERNAL}" && hide "${INTERNAL}"
elif [ "${OPTION}" == "${OPT_BOTH}" ]
then
  show "${EXTERNAL}"
  show "${INTERNAL}"
fi

X11 Applications And Games Are Blurry

Gamescope can be used to start an Xwayland session for an individual application, which will be rendered at 1:1 pixels.

This wrapper may be used to launch an X11 application at the first display's native resolution. Requires yq.

#!/bin/bash

set -o pipefail

# fetch the first display
if ! VARS="$(way-displays -y -g | yq '.STATE.HEADS[0] | "NAME=\"" + .NAME + "\" DESCRIPTION=\"" + .DESCRIPTION + "\" WIDTH=" + .CURRENT.MODE.WIDTH + " HEIGHT=" + .CURRENT.MODE.HEIGHT')"; then
	exit 1
fi

# extract info
eval "${VARS}"
printf "name:   %s\ndesc:   %s\nwidth:  %d\nheight: %d\n" "${NAME}" "${DESCRIPTION}" "${WIDTH}" "${HEIGHT}"

# launch arguments with gamescope
gamescope \
	--prefer-output "${NAME}" \
	--output-width "${WIDTH}" --output-height "${HEIGHT}" \
	--nested-width "${WIDTH}" --nested-height "${HEIGHT}" \
	--adaptive-sync \
	"${@}"

Omit -output-width and --output-height in the event of "source rectangle out of buffer bounds" and repeated "source rectangle out of buffer bounds" failures.

Adaptive sync may not function unless running gamescope as a tty session: https://github.com/ValveSoftware/gamescope/issues/975

gamescope-run-native -- glxgears -fullscreen

Using 2 xwayland instances allows the steam window itself to be resized.

gamescope-run-native --xwayland-count 2 --steam -- steam

Launch Options Command: mangohud gamescope-run-native --fullscreen -- %command%

For reference, the steam deck uses the following to launch steam:

gamescope \
	--generate-drm-mode fixed \
	--xwayland-count 2 \
	-w 1280 -h 800 \
	--default-touch-mode 4 \
	--hide-cursor-delay 3000 \
	--max-scale 2 \
	--fade-out-duration 200 \
	-e \
	-R /run/user/1000/gamescope.1zn7D7r/startup.socket \
	-T /run/user/1000/gamescope.1zn7D7r/stats.pipe \
	-O *,eDP-1 \
	--cursor-hotspot 5,3 \
	--cursor /usr/share/steamos/steamos-cursor.png
