AFAIK, Weston uses "libinput", so I assigned "WL_SEAT" of input devices
Hi,
should that not be ID_SEAT?
Also remember to set it for the DRM device you want to use with the
seat.
ID_SEAT is for physical seats which is what you are setting up. WL_SEAT
is for "seats" inside a single Weston session so that you can group
input devices to different wl_seat Wayland objects. Particularly, two
mouse devices in the same wl_seat move the same pointer, while two
mouse devices in different wl_seats gets you two independent pointers
in the same session.
In fact, this is the thing I don't quite understand. In what situations
having 2 logical seats inside 1 physical seat is useful? And what seats
the event "wl_registry::global" announces--logical or physical?
Anyway, I set WL_SEAT and ID_SEAT to "seat1" before writing to this
list. For example. {{{

Have you tried using the --seat command line argument to make Weston's
DRM-backend pick a seat other than the default "seat0"?
Okay, Weston drives "seat1" if given the option "--seat=seat1" and no
configuration file. But "seat0" where I start Weston freezes until
Weston terminates.
Why should I run "weston-launch" from a virtual terminal? I would like
to run it from "gnome-terminal".
BTW, the option "--connectorid=card1-VGA-2" gives the "unhandled option"
error.
You would be running an instance of Weston per each seat / gfx card.
It is an old dream of mine to attach all seats to 1 videocard. Is it
possible? If not, is this a limitation of Weston, Wayland, or Linux? I
mean, may 2 processes drive 1 videocard?
