cluster dashboard opens on second display when multiple displays are enabled

Fixed

Description

I work with AGL Reference Hardware board, it has two HDMIs: HDMI-A-1 and HDMI-A-2. By default, only HDMI-A-1 is enabled.

I run agl-cluster-demo-platform image.

When I enable second HDMI, cluster applications moves to its display.

I have found in https://gerrit.automotivelinux.org/gerrit/gitweb?p=apps/agl-cluster-demo-dashboard.git;a=blobdiff;f=app/main.cpp;h=3c460d53cde791d0ec3949095346763f072108b1;hp=a5b9ecead3353431e22aaea3bc61e7cedb47ceb0;hb=233faba31d4ed8b3a4d6e758275b2103a5c69ef3;hpb=843114c08eabcd51a58c94c7e9130652b86b1449 that cluster application looks for primary display in Qt.

I don't understand why HDMI-A-2 becomes primary display. In my opinion first HDMI should be primary display.

We can add to the potential feature list for 2021 in consultation with the IC EG.

cluster-gauges is like homescreen, a client shell, and not an application, so we can't really migrate it that way. It has to be started straight in on another output (like there an environment variable for homescreen), or we "enhance" the compositor to use the same agl-shell-app-id for the client shell. Currently there's no code in the compositor to deal with the client-shell, just applications.

Would like to get some feed-back on the matter before I write something up.  or  what is the take on this? Is this something that is worth looking into?

Well, the logs shows that the appid option is not found. I'm going to do a short test and get back to you.
