3. Display platform[edit | edit source]
Two solutions exist to display the web browser:
- using eglfs
- using Wayland

- Weston must be started. If you have stopped it, you can restart Weston with the following command
Board $> systemctl start weston@root
- Install qtwayland
Board $> apt-get install qtwayland
- Set Wayland egl as display platform
Board $> export QT_QPA_PLATFORM=wayland-egl
- Launch the Python web browser
Board $> qt-wpe-simple-browser <url http://>
or
Board $> python3 web_browser.py <url http://>
3.2. eglfs[edit | edit source]
- Stop the Weston application
Board $> systemctl stop weston@root
- Set eglfs as display platform
Board $> export QT_QPA_PLATFORM=eglfs
- And set the following variables
Board $> export QML2_IMPORT_PATH='/usr/lib/qt5/qml/'
Board $> export QT_QPA_EGLFS_ALWAYS_SET_MODE='1'
- Launch the web browser
Board $> qt-wpe-simple-browser <url http://>
or
Board $> python3 web_browser.py <url http://>

With HDMI connection, it is advised to use the following kms eglfs_config.json config file in order to avoid cursor rendering issue.
{
"device": "/dev/dri/card0",
"hwcursor": false,
"pbuffers": true,
"outputs": [
{
"name": "HDMI1",
"mode": "1280x720"
}
]
}
Set Qt variable to use the json config file: Board $> export QT_QPA_EGLFS_KMS_CONFIG='/home/root/eglfs_config.json' |
