./configure -release -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$TOOLCHAIN/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot $ROOTFS -prefix /usr/local/qt5


This plugin writes directly to the framebuffer. Only software-rendered content is supported. Note that on some setups the display performance is expected to be limited.

The linuxfb plugin allows specifying additional settings by passing them in the QT_QPA_PLATFORM environment variable or -platform command-line option. For example, QT_QPA_PLATFORM=linuxfb:fb=/dev/fb1 specifies that the framebuffer device /dev/fb1 should be used instead of the default fb0. Multiple settings can be specfified by separating them with a colon.


When no windowing system is present, the mouse, keyboard and touch input are read directly via evdev or using helper libraries like tslib. Note that this requires that devices nodes /dev/input/event* are readable by the user. eglfs has all the evdev input handling code built-in, while linuxfb relies on the traditional and somewhat limited -plugin command-line parameters.

Input on linuxfb

To enable keyboard, mouse, touch or tablet support with linuxfb, pass QT_QPA_GENERIC_PLUGINS=evdevkeyboard,evdevmouse,evdevtouch,... in the environment or, alternatively, -plugin evdevkeyboard, -plugin evdevmouse, -plugin evdevtouch, or -plugin evdevtablet on the command-line. Most of these can take a device node parameter, for example QT_QPA_GENERIC_PLUGINS=evdevmouse:/dev/event1, in case the Qt's automatic device discovery (based either on libudev or a walkthrough of /dev/input/event*) is not functional or misbehaving.
