Yeah.

You don't have write permission to the named pipe, that's the
culprit. This needs fixing in weston.

To me it's a bit of a surprise to hear that weston-desktop-shell
is running fine (it draws the panel and background), maybe weston
runs it as root then.

Installing weston without suid should be a workaround.
