Hi,

 

My configuration is to output 2 LVDS on a solo board which means

                          +--------> IPU0 DP-BG : /dev/fb0 <----> /dev/video16

LVDS #0  -------+

                          +--------> IPU0 DP-FG : /dev/fb1 <-----> /dev/video17


LVDS #1      --------- IPU0 DC : /dev/fb2 <-----> /dev/video18

 

I'm running LXDE as my desktop on /dev/fb0. When I play video on /dev/vido17, it just overlaid on top of video16. There's no problem to get back to the desktop after video playback is done. However, if I put the video playback on either video16 or video18, the xwindow just lost the control of /dev/fb0 that results in no desktop after video playback. The link between fb0 and xwindow is broken. I can't get the xwindow unless I stop/start xserver again. I wonder if there is a way to prevent this happen. Any comments will be appreciated. Thanks.
