In short, I had to modify the /etc/X11/xorg.conf accordingly, then $ startx -- layout seat0 -config xorg.conf.multiseat. I am now trying to migrate to the new facilities for multiseats from loginctl[2] and Xorg 1.16 with rootless X[3]. Documentation is very rare, and I find it difficult to set up the global scheme. I understand from loginctl(1) I have to first create 1 new seat with loginctl using 1 existing graphic device: $ attach seat1 /sys/bus/pci/device/:00:01.0@ (my graphic card as listed by $lspci). Then, I will attach a usb keyboard mouse the same way, right ? Now, as for the monitor session layout, i have no idea how to deal with it and the global /etc/X11/xorg.conf . Same as before or is there now a more specific way? Then, once I have created seat1, I am left with two seats : seat0 and seat1. I understand I have to bind a user session login to a specific seat, right ? Concretely, how do it ? Thank you for any hint/pointer/suggestion about the path to follow. Note that the multi-seat stuff is about assigning kernel devices to seats. Drivers that do not follow the kernel driver model and DRM are hence not really supported (such as the nvidia driver), and if you want to split a single gfx card into two seats, then we can't cover this either. For the first issue please use the open source nvidia driver, or work with nvidia, to get them to open up the closed source one. For the second issue, please work with the driver authors, to possibly allow turning one graphics card into two DRM devices, so that we can individually assign them to different things.

Re: [systemd-devel] loginctl - multi-seats
provided you tag another suitable device (e.g. a USB hub) as master-of-seat and attach it to seat-1. I will switch to nouveau, as I do not want to go this way. About configuring multiseat using a single multi-head graphics card, the only current available way to do this is with nested X servers: I will forget this trick. As seats will not ask for huge graphic ressources (no hard gaming), best is to engage in a clean fashion with DRM support drivers. TY for your long answer. I see this kind of stuff is of interest, and solid documentation quite rare. ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

I would try with an openSUSE/Fedora Live CD first, because I know it works and if it works for you too but fails on Arch, you may be missing some patches/config and we could see where it fails maybe.

Until now, I have been enable to set a dual seat following the
archwiki[1]. In short, I had to modify the /etc/X11/xorg.conf
accordingly, then $ startx -- layout seat0 -config
xorg.conf.multiseat.
I am now trying to migrate to the new facilities for multiseats from
loginctl[2] and Xorg 1.16 with rootless X[3]. Documentation is very
rare, and I find it difficult to set up the global scheme.
I understand from loginctl(1) I have to first create 1 new seat with
loginctl using 1 existing graphic device:
$ attach seat1 /sys/bus/pci/device/:00:01.0@ (my graphic card as
listed by $lspci).
Then, I will attach a usb keyboard mouse the same way, right ?
Now, as for the monitor session layout, i have no idea how to deal
with it and the global /etc/X11/xorg.conf . Same as before or is there
now a more specific way?
Then, once I have created seat1, I am left with two seats : seat0 and
seat1. I understand I have to
bind a user session login to a specific seat, right ? Concretely, how do it ?
Thank you for any hint/pointer/suggestion about the path to follow.

But in fact, I have one single card but can plug two monitors: one on HDMI and the other one on VGA. Shall i understand there is nothing to do with these two plugin outputs? To be more precised, I have on the back of my computer two HDMI ports and two Display Ports. Can't these two ports be used instead of buying a usb display link ? -- google.com/+arnaudgabourygabx ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
