Mir Kiosk Chromium

Mir Kiosk Chromium enables to run web based kiosks on Ubuntu Core. This is forked from Gerry Boland's mir-kiosk-chromium

Build

git clone https://github.com/zhex900/mir-kiosk-chromium

cd mir-kiosk-chromium

docker run --rm -v $PWD:/project -w /project zhex900/snapcraft:core18 snapcraft

Install

This is tested on Ubuntu Core 18 and 20

First install mir-kiosk

sudo snap install mir-kiosk

Install this snap package

sudo snap install ./mir-kiosk-chromium_87.0.4280.66_amd64.snap --dangerous --devmode

Configuration

To customize the startup url for chromium use:

sudo snap set mir-kiosk-chromium url="https://yoururl.com"

Set browser refresh interval. Default is 1hr (60 mins)

sudo snap set mir-kiosk-chromium resettime=60

Show nav bar

sudo snap set mir-kiosk-chromium shownav=true

Hide cursor (true/false)

sudo snap set mir-kiosk-chromium hidecursor=true

Disable kiosk mode (true/false)

sudo snap set mir-kiosk-chromium disablekiosk=true

Screen orientation

sudo vim /var/snap/mir-kiosk/current/miral-kiosk.display. Append this to the end of the file.

  kiosk:
    cards:
    - card-id: 0
      DisplayPort-1:
        orientation: right # left or normal

Apply the new kiosk layout

sudo snap set mir-kiosk display-layout=kiosk

Remove chrome profile lock on boot

When the kiosk is ungracefully shutdown, like lost of power. Chromium will display a white page asking to unlock existing profile. To remove this on reboot. Existing Chrome profile needs to be removed.

sudo vim /etc/systemd/system/snap.mir-kiosk-chromium.mir-kiosk-chromium.service

Add this before ExecStart. This will remove the profile lock when chromium crashes or ungracefully reboots.

ExecStartPre=/usr/bin/rm -rf /root/snap/mir-kiosk-chromium/current/.config/chromium/SingletonLock
ExecStartPre=/usr/bin/rm -rf /root/snap/mir-kiosk-chromium/current/.config/chromium/SingletonCookie
ExecStartPre=/usr/bin/rm -rf /root/snap/mir-kiosk-chromium/current/.config/chromium/SingletonSocket

Change Restart to always. Restart=always

sudo systemctl daemon-reload

sudo snap restart mir-kiosk-chromium
