Display manager for kde5/openrc with multiseat?

[Apollo_Futurae]

For some time, I have been using a multiseat setup, with kde4 and kdm, under openrc. It is working nicely.

Now, I'm considering upgrading to kde5, but it's not clear to me what display manager I could use:

• the preferred new display manager, sddm, does not currently handle multiseat;
  
• I would like to stay on openrc and keep out systemd as much as possible, so LightDM is then not an option, or is it?
  
• Is it even possible to use kdm with kde5? This is not clear to me from the kde upgrade guide.

What would be the best bet?

I've used LightDM with Plasma 5 and OpenRC in the past and it worked fine

As for KDM, I've heard mixed reports but wouldn't recommend it - it's completely unsupported upstream and will be removed along with the rest of Plasma 4.

Can someone who knows how to aply these kde settings to lightdm.conf help me please. Theres 3 seats started with kdm..

[X-:0-Core]
AutoLoginEnable=false
AutoLoginLocked=false
AutoLoginUser=markus
ClientLogFile=.xsession-errors
ServerCmd=/usr/bin/X -nolisten tcp -novtswitch -config /etc/X11/xorg_left.conf -br -sharevts vt12

[X-:1-Core]
ClientLogFile=.xsession-errors1
ServerCmd=/usr/bin/X -nolisten tcp -novtswitch -config /etc/X11/xorg_right.conf -br vt12

[X-:2-Core]
ClientLogFile=.xsession-errors2
ServerCmd=/usr/bin/X -nolisten tcp -novtswitch -config /etc/X11/xorg_middle.conf -br -sharevts vt12

THis was so easy and it has worked like a dream with games and all

But how to apply that to lightdm.conf ??

To me those settings look very much like LightDM configs.
Here's my two-seated config:

I think it should work with this server command below.. But not able to verify that because I havent updated anything else but system because this kdm thing (few months now). I havent had time to think this and we really need those three seats Lightdm command produses some icu 57 missing error so this could take a few days

xserver-command=/usr/bin/X -screen screen0 -config /etc/X11/xorg_left.conf

Or does it have to be scripted that config for it to work? Or what there is in display-setup-script?
