I am setting up a "kiosk" mode display but Im having a hard time getting chromium to show properly on raspbian login. If I comment the line out, and manually start chromium, it will show. If I start using various different startup arguments in /etc/xdg/lxsession/LXDE-pi/autostart chromium starts but no window shows. How do I know? ps aux | grep chromium shows it's started up. If I try to open a browser after that, it will just say "opening in existing browser session" which is obviously also a problem because the existing browser session isn't showing.

I am guessing that it has something to do with the "restore pages" dialogue box, because if I start chromium manually, without any autostart scripts, it will ask me if i want to restore pages. But, I'd assumed --disable-restore-session-state flag would have taken care of that. I did find another threat that mentioned I should flag the opening address with --app but that also didn't work. Here are variations of what I've tried in my autostart script...

@chromium-browser --start-fullscreen --ignore-certificate-errors --disable-restore-session-state -
@chromium-browser --start-fullscreen --ignore-certificate-errors --disable-restore-session-state ---app=
@chromium-browser --kiosk --app=
@chromium-browser --kiosk

@chromium-browser --kiosk --force-device-scale-factor=2.0 --user-data-dir=/home/pi/.config/chromium-display1 --app=https://[first site]
@chromium-browser --kiosk --force-device-scale-factor=1.0 --user-data-dir=/home/pi/.config/chromium-display2 --window-position=1921,0 --app=https://[second site]

works for me. I am using it for two different displays so you can remove the second one if you don't need it.

  • That's essentially the same as what I'd already done @chromium-browser --kiosk --app=

I was able to get this to work by adding the --app-auto-launched flag to one of my previously mentioned entries.

@chromium-browser --kiosk --app-auto-launched --app=
