how to write a system service to auto startup chromium on wayland with non-root user?

gonewtinwind

Hi Joshua  & all

 

I use the below system service can auto startup chromium on maaxboard wayland with root user, but it's not safe with root user, so I need to startup with non-root user.

I tried to modify it somewhere, but not work.

any help?

 

my service ,you can see it's root user with --no-sandbox option :

/etc/systemd/system/chromium.service

----

 

Description=launch chromium

 

[Service]

User=root

Environment=DISPLAY=:0

Environment=XDG_RUNTIME_DIR="/run/user/0"

Type=oneshot

ExecStart=/bin/sleep 15

ExecStart=/usr/bin/chromium --no-sandbox --disable-infobars --user-data-dir=/tmp/chromium --gpu-no-context-lost --enable-gpu-rasterization --start-fullscreen --kiosk --no-first-run --incognito http://localhost:3300/rpi.html > /dev/null 2>&1 &

 

[Install]

WantedBy=multi-user.target

 

ref:can not auto startup chromium(chromium-ozone-wayland)

  • Hi Peter,

     

    Did you have success in finding a solution to this?

     

    Here is our reccomendation

    "

    It could be specified one user in system service , For example, let user ‘avnet’ start this service, then modify the property:

    /etc/systemd/system/chromium.service

    [Service]

    User=avnet

     

    Another method is to delete the property ‘’ User=’’ , then any user could use the service.

    "

     

    Thanks,
    Josh

    I posted NXP too, but no solutions.

    I tried to research online. but only old solutions for rc(old skills worked well before) not systemd.

     

    https://community.nxp.com/t5/i-MX-Processors/how-to-write-a-system-service-to-auto-startup-chromium-on/m-p/1275666#M1739…

    any suggestions?

  • in reply to gonewtinwind

    Hi Peter,

     

    This should solve your problem.

     

    Refer to the following steps to solve this problem:

    1  start the weston desktop on maaxboard with ‘avnet’ user. (Refer to the guide in PDF form below for detailed example)

    2  create a service file and enable this service to automatically start Google Chrome

       maaxboard:~# vi /etc/systemd/system/chromium.service

    [Unit]

    Description=chromium Browser

    After=weston.service

     

    [Service]

    User=avnet

    Environment=DISPLAY=:0

    Environment=XDG_RUNTIME_DIR="/run/user/1000"

    Type=oneshot

    ExecStart=/usr/bin/chromium --start-fullscreen > /dev/null 2>&1 &

     

    [Install]

    WantedBy=multi-user.target

       maaxboard:~# sudo systemctl daemon-reload

       maaxboard:~# systemctl enable chromium.service

     

    Note: in the chromium.service file , the number 1000 is the user's id.

    Use the command “id avnet” to get the user's id value

     

    3  reboot the system.

     

    Detailed guide see document - https://avtinc.sharepoint.com/:b:/t/ET-Downloads/EQCw2IF8l89Jo3yJokpDgHABeQbHIp2qwwOVyN759U4odg?e=ePHugh

     

    Thx,

    Josh

    hi Josh,

    Thank you very much.

    did you test it on your maaxboard(yocto-zeus)? I followed your guide, but it still does not work.

    Hi Peter,


    I will verify the OS used.

    Can you share similiar screen captures as shown in the user guide provided to make sure we are on the same page?

     

    Thx,

    anyway,I did the way as your guide many times in both maaxboard and iwave  before, but did not work! I asked the same question on NXP, but there was no solution either
