URL doesn't change

[vivien]

Hi there, I'm setting a different URL in the config file but the browser will always display the builtin default ossystems website:

root@beaglebone:~# cat /etc/qt-kiosk-browser.conf
{
    "URL": "https://github.com/OSSystems/qt-kiosk-browser",
    "RestartTimeout": 0,
    "ScreenSaverTimeout": 0
}
root@beaglebone:~# /usr/bin/qt-kiosk-browser --no-sandbox -platform linuxfb /etc/qt-kiosk-browser.conf
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QtWebEngine::initialize() called with QCoreApplication object already created and should be call before. This is depreciated and may fail in the future.
This plugin does not support createPlatformOpenGLContext!
Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created.

Am I doing something wrong?

If not, is there another way to provide an URL, like a webengine/chromium command line argument or environment variable?

Thank you.

The URL must be set using the qt-kiosk-browser.conf file. You can set the URL in there.

Please take a look at the commands above, that's what I've done. I used the qt-kiosk-browser github URL instead of the default https://www.ossystems.com.br. The issue is that only https://www.ossystems.com.br will be displayed, regardless the settings. Hence my two questions.

It might have something to do when running qt-kiosk-browser as root with --no-sandbox, not certain yet.

I found the problem. The issue indeed came from how I was invoking qt-kiosk-browser as root:

qt-kiosk-browser -platform linuxfb --no-sandbox /etc/qt-kiosk-browser.conf

strace shows that qt-kiosk-browser is trying to load the configuration file --no-sandbox which obviously doesn't exist, silently falling back to the built-in URL value.

To fix this, the chromium options must be passed after the qt-kiosk-browser options:

qt-kiosk-browser -platform linuxfb /etc/qt-kiosk-browser.conf --no-sandbox

or via an environment variable like this:

QTWEBENGINE_CHROMIUM_FLAGS="--no-sandbox" qt-kiosk-browser -platform linuxfb /etc/qt-kiosk-browser.conf

I'm opening a new issue to request erroring out when the provided configuration file does not exist.
