Comment (by rudolfc):
Another comment: So with the HDMI adapter I see that both FDI links (A and
B) seem correctly and individually programmed/accessed. You can see that
the internal panel uses a single lane, where the HDMI connection uses 2
(1920x1080 should be possible there that way).
But I am missing panelfitter messages in the syslog, so are you sure you
installed the V4 driver correctly? You are running on the current git
version from the looks of it?
If you have the V4 correctly installed, and you set a mode that should be
compatible for both screens, you might have a correct desktop on the
external screen.
Note however that dualscreen output is not yet supported (did not
explicitly look into that yet) so on a laptop it's a bit unsure how this
all works out for now.
If you do more tests, post info here I'd say. Can you BTW in the bootmenu
(so before the icons screen) set your external screen's native resolution?
or does this menu not offer that? Anything above 1920x1080?
If so, I'd love a syslog from that to see what it does for the lanes (HDMI
adapter).
But, don't use it too long, since it's not supported by your internal
panel. You should in the end set a mode that's compatible for both screens
at the same time (so lower or at native interal screen resolution).
