I have an issue when I add tcpdump and htop to the file ~/build-webos/meta-webosose/meta-webos/conf/distro/include/webos.inc using the two commands IMAGE\_INSTALL +="htop" and IMAGE\_INSTALL +="tcpdump." After successfully building and flashing to the Raspberry Pi 4 board, the system boots up normally. However, when I connect the HDMI port to an external monitor, the screen is black, displaying only the mouse cursor, which can be moved.

I cannot reproduce this issue. I tried with as below

$ git diff  
diff --git a/meta-webos/recipes-core/images/webos-image.bb b/meta-webos/recipes-core/images/webos-image.bb  
index 8a8e6cc4b19..6edb3c38047 100644

Please try it again.

I appreciate your support.  
I tried to rebuild it, It is OK.
