This is a snap package of Qt5 and Oxide, with default EGLFS QPA, so the WebView works without display server.
The amd64 version is using eglfs_kms backend (KMS/DRM), and the RPi2/3 version is using eglfs_brcm backend from Broadcom's dispmanx/EGL driver.
Install from beta channel in the store:
sudo snap install oxide-digitalsignage --devmode --channel=beta
Or download snap oxide-digitalsignage_1_amd64.snap, and install locally:
sudo snap install oxide-digitalsignage_1_amd64.snap --dangerous --devmode
The --devmode parameter is required since EGLFS scans video devices, and currently there's no plug for that.
Stop the X11 session, and if you have more than one graphic card, you'll need to disable the other one (nouveau for nVidia, radeon for AMD), too:
systemctl stop lightdm
sudo chmod a+rw /dev/dri/*
sudo modprobe -r nouveau
Then launch the WebView by:
/snap/bin/oxide-digitalsignage.start-oxide --url="http://google.com/ncr"
You'll need to add ppa:ci-train-ppa-service/stable-phone-overlay PPA for more recent packages:
sudo add-apt-repository ppa:ci-train-ppa-service/stable-phone-overlay
Then build it with:
snapcraft snap
There's prebuilt Qt5 binaries needed that's linked against OpenGLES, that will be extracted via tar-content plugin and copied over to prime/. We could try to use stage packages like libqt5gui5-gles in the future.
For Raspberry Pi2/3 please refer to rpi2 branch.
