im trying to get working on HDMI screen, i get blank screen,even set the mode manual via /etc/directfbrc not working.the SOC board have 2 connectors,composite video & HDMI. another test using psplash ported to DRM psplash-drm working succesfully. here are directFB-examples output :

Displaying is done only on the first connector found by default, so you probably get df_andi displaying on your composite video connector.

With multiple connectors, setting connected-outputs=multihead in /etc/directfbrc allows to select which connector to use: in this case it is necessary to use dfbinfo from DirectFB-tools to list the primary layer ids.
Then add in /etc/directfbrc: primary-layer="id of the primary layer corresponding to the HDMI connector in your case"

This is the principle, but a few months have passed since the last time I tested this kind of configuration.

How to manually set resolution?

Yes, it is necessary to also set a resolution supported by the connector when connected-outputs=multihead is set (if the default resolution with the first connector is not supported by the other connectors). This should be improved as a correct mode could be determined automatically.

To select the HDMI connector here, I would say that /etc/directfbrc contains for example:

connected-outputs=multihead
primary-layer=1
mode=1280x720

Do you have df_andi displayed on your composite video connector with the default configuration?

i cant test composite display i dont have the cable,but the hdmi work for sure with splash-drm, i dont think its hardware problem.

i concern with "(!) *** ONCE [no mode found for 1280x720 at 0 Hz", and "!) DRMKMS/Layer: drmModeSetCrtc( crtc_id 42, fb_id 46, xy 0,0, connector_id 34, mode 720x576@50Hz ) failed at index 1!" which is connector id 34, crtc id 42 are belong to hdmi.

here are the output :

its work properly with this configuration

system=drmkms
drmkms=/dev/dri/card0
module-dir=/lib/directfb-2.0-0
connected-outputs=multihead
primary-layer=1
mode=720x480

not working with 1366x768 nor 1920x1080

im create quick patch at here,the code not clean but its work just like i want, with this patch just need to set primary-layer to corresponding connector and set mode with widthxheight@vrefresh, in this case :

primary-layer=1
mode=1366x768@60Hz

It's great that you can run DirectFB2 on your platform!
I agree that the support for multiple connectors with the different possible modes needs to be improved in the drmkms system module.
