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
hello ,
please tell me how to use command to display different video to different display. i have seach for some messenge on internet ,but always use overlaysink,but in I.MX8M Plus BSP it was not exist.
