Let me know if you have any success.

Thanks,

I have find the solution. it's hard to do in systemd(maybe it's new for me):

1. create environmen file chromium first:

cat /etc/default/chromium
#OPTARGS="--xwayland --use-g2d=1"

XDG_RUNTIME_DIR="/run/user/0"

2. create a chromium.service file at /etc/systemd/system/chromium.service , put in the environmen file   like following:

[Unit]
Description=launch chromium

[Service]
User=root

Type=oneshot

ExecStart=/bin/sleep 20

EnvironmentFile=-/etc/default/chromium
ExecStart=/usr/bin/chromium --no-sandbox --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

3. run: systemctl enable chromium or

directly make a symbol link at :

/etc/systemd/system/multi-user.target.wants/chromium.service -> /etc/systemd/system/chromium.service

at  /etc/systemd/system/multi-user.target.wants/. to run ln -s  chromium.service  ../chromium.service  to make this link

.

try to run systemctl start chromium to test. works well.

power off and power on or restart . work well.

done

Thank you

First, you should set the User option to your user to avoid running chromium as root, then set WantedBy to your DE's .target.

Probably a better option would be to use your DE's autostart feature, made for this exact purpose of starting GUI programso on boot

hi @Mate Varga,

how to avoid running chromium as root? I tried my time to run as myuser, eg:

ExecStart=sudo -u myuser /usr/bin/chromium  --gpu-no-context-lost --enable-gpu-rasterization --start-fullscreen --kiosk --no-first-run --incognito http://localhost:3300/rpi.html > /dev/null 2>&1 &

but can not be successful. so I have to use root user.

how to write the chromium.service?
