Hi, I would like to run our Qt application (it is basically displaying several QWebEngineViews) in a dual screen setup on the i.MX6 board. Those screens are connected to LVDS - one is on /dev/fb0 and the second is on /dev/fb2. We are able to achieve what we want by running Xorg with 2 devices and 2 screens in configuration. The device Xorg driver has to be "fbdev" as "vivante" xorg driver works only with /dev/fb0 (checked - while X starts fine it crashes when trying to run OpenGL application on the second screen). So we do not have hardware accelerated OpenGL which is a huge performance hit.
So my question is: Is it possible to run some simple QtWayland compositor that would control both displays? So we can have one HW accelerated application displayed on both screens? Or maybe some other way to get this working? And how should I setup the Vivante libraries to make the QtWayland compositor and other applications to run (I mean there are libEGL-fb.so and libEGL-wl.so while the compositor should be ran with eglfs and other apps with wayland platform plugin, right?) Best Regards, Filip Piechocki
