Вот моя последняя установка киоска для протокола.

В ~/.xinitrc я добавил:

# disable screen saver
xset s off
xset -dpms

# start window-manager
i3

В ~/.i3/config я добавил:

# Setting workspace to monitors
workspace 1 output HDMI1
workspace 2 output HDMI2

# tie each browser to each monitor
for_window [class="^chromium-left$"] move workspace number 1
for_window [class="^chromium-right$"] move workspace number 2

exec ./start-browsers.sh

И для запуска браузеров

./start- browsers.sh

#!/bin/bash

left_url="http://whatever/url/for/left/monitor"
right_url="http://whatever/url/for/right/monitor"

tmpdir1=$(mktemp --directory)
tmpdir2=$(mktemp --directory)

left_target="chromium --new-window $left_url \
--user-data-dir=$tmpdir1 \
--class=chromium-left \
--no-first-run \
--disable-restore-session-state \
--no-default-browser-check \
--disable-java \
--disable-translate \
--disable-infobars \
--disable-suggestions-service \
--disable-save-password-bubble \
--start-fullscreen"
right_target="chromium --new-window $right_url \
--disable-java --user-data-dir=$tmpdir2 \
--class=chromium-right \
--no-first-run \
--disable-restore-session-state \
--no-default-browser-check \
--disable-translate \
--disable-infobars \
--disable-suggestions-service \
--disable-save-password-bubble \
--start-fullscreen"

# start app for left screen
i3-msg 'workspace 1'
$left_target &

# start app for right screen
i3-msg 'workspace 2'
$right_target &

# hide mouse pointer
unclutter &
