imx8qxp 双屏显示的应用问题

各位:

        我们基于NXP kernel-4.14.98版本开发了demo板,目前已经成功驱动2个LVDS屏幕,可以通过鼠标将QT应用拖拽到不同的屏幕上显示。为了实现双屏同显和双屏异显,我们参考了imx6的配置方法,但imx8qxp显示框架为drm,imx6的方法在imx8上无效。目前我们遇到的问题:

        1.双屏异显:在命令行模式下,我们要如何配置才能让2个屏幕显示指定的内容?比如,LVDS-1上显示QT-APP-1应用程序,LVDS-2上显示QT-APP-2应用程序。

        2.双屏同显:如何配置才能实现双屏同显?

Yocto工程为4.14.98,文件系统采用NXP编译的固件,图形后端/桌面为wayland/weston.

try to use the Qt5_Cinematics is under /usr/share/cinematicexperience-1.0/
you have to click with the mouse at the destination monitor, then run the cinematics with &, click with the mouse at the second display, and run the cinematic again.

感谢回复。

采用键鼠的方式我知道如何实现双屏异显;

但我们更关心的是如何配置wayland/weston桌面,使得能够不用键鼠,而是使用命令终端实现双屏同显和双屏异显?

if you playback the video, you can use gstreamer to display different video to the different display, but if you display weston desktop, you need to use mouse
