Hi,
agl-shell-app-id takes a string as an argument. The application has to
set it up. You can either grab that by grepping for app_id request when
starting the application env variable WAYLAND_DEBUG=1 over the cmd line,
or verify the systemd journal log of the compositor. The compositor logs
the full application id. After that you would modify the ini file and
restart the user session.

Hi Marius,
Thanks for your inputs, could you please simplify the below comment, assuming I have HDMI and DP monitor, IVI launcher has booted on HDMI monitor, and I need to run glmark2 on DP.
You should be able to display another application on other output my modifying the ini configuration file as specified at [1]. The application needs to have an application id set-up, otherwise we won't be able to place it accordingly. You should be able to corroborate that by checking out the systemd journal for agl-compositor. Keep in mind you need to restart the user session for changes to be applied.
From logs I see agl compositor app ID = 581?
Apr 25 18:26:13 amd-v2000 agl-compositor[581]: [18:26:13.637] Command line: /usr/bin/agl-compositor --config /etc/xdg/
weston/weston.ini --idle-time=0
That's the PID of the compositor, nothing with the app_id. See
https://wayland.app/protocols/xdg-shell#xdg_toplevel:request:set_app_id
for more info.
I have kept my Weston.ini output something like below
===================
[output]
#name=DP-1
name=HDMI-A-1
#transform=rotate-90
agl-shell-app-id=573
=====================
Best Regards,
Rahul

Subject: Re: Boot agl ivi demo with two physical display monitor(clone or extended)
Hi Rahul,
There's nothing to be displayed on the other screen and by default there's black curtain installed on it. Even if it wasn't you'd still see black/blank screen. Keep in mind that the application itself doesn't extend to cover the other screen.
You should be able to display another application on other output my modifying the ini configuration file as specified at [1]. The application needs to have an application id set-up, otherwise we won't be able to place it accordingly. You should be able to corroborate that by checking out the systemd journal for agl-compositor. Keep in mind you need to restart the user session for changes to be applied.
For cloning, we have similar configuration entry, it's called "same-as"
where you specify the output being a clone of another. This is indeed undocumented but it is also untested, so I don't know if this works or not.
Further more, this requires proper hardware, meaning that the underlying hardware would power up all connectors from same/shared source.
Underneath there's no duplication/cloning per-se, the same buffer is being scanned out to all outputs/connectors attached to that source.
I believe the DRM backend would actually complain/let you know if the ^ aren't possible.
Hope this helps,

Hi All ,
When I try to boot two displays (HDMI and DP) with agl demo image,
display boots only with HDMI monitor, and DP monitor remains blank.
I think we can make both monitor work as extended and clone mode, do
we have any documentation or steps for this.
Best Regards,
Rahul
