Nothing is switching to tty7 as I'm connected via UART so different
output.
Anyway weston starts properly on tty7 and is displayed correctly on
the
display.
Well, Weston may start and be displayed, but are you sure the local
console's current VT is VT7?
I can. If I connect a keyboard, Ctrl+Alt+F1 => Black screen, Ctrl+Alt+F7
=> weston

No, ssh can connect (I get the content of /etc/issue.net) but after
that
it hangs and will not ask for the password.
Or if I had an ssh connection already opend, and want to "ps aux" if
weston still running. I call "ps aux" and it will never show anything
or
stop. It just hangs in there.
Huh. I wonder if Weston(-launch) is attempting to control the serial
tty
somehow...
Does a simple 'echo foo' work instead of 'ps'?
further testing revealed, that if I'm fast enough ps aux will output
stuff but stop at one point.
So I guess ps stops working, when "It" happens. Whatever "It" is.
> Are you unable to switch vts after exiting weston?
Ctrl+Alt+F1? Never tried, but I guess if I can, I would be able to
login, cause a login via UART (which is the same as locally) hangs
too.
Well, would be nice to know if your serial tty is jammed or if it is
actually the login procedure... sounds like the tty, though. But that
doesn't explain ssh login getting stuck.
How can I check if tty is jammed?

I tried weston-launch without --tty too.
Unfortunately I don't have much experience in launching weston from a
serial connection. I would recommend still trying to use weston-launch
with both --tty and --user and using a normal user as the user, not
root.
You may need to be root to run openvt and/or weston-launch. Please try
also to make openvt switch (-s) to the new VT before it execs
weston-launch.
You might also try weston-launch with --tty and --user but without
openvt.
As --user is dedicated to root; weston-launch with --user and --tty
starts but doesn't work either as
XGD_RUNTIME_DIR is then root's not that from the user.

libwayland: unable to open lockfile /run/user/0/wayland-0.lock check
permissions

So currently I can run weston-launch only with openvt, with or without
--tty and not with --user.
Any further ideas? ... As I run the app in kiosk mode and don't need to
stop weston, it is just annoying, that I have to reboot when I sometimes
need to restart weston.
Cheers,
Thilo
