Cannot start Lighdm in separate Xephy server

Hello!

I tried to start a ligdm session in a separate x-server (running xephyr on display=:7) and used:
>DISPLAY=:7 lightdm
wondering, that I need permissions ...
bash: lightdm: command not found

Then I tried:

sudo DISPLAY=:7 lightdm

** (lightdm:580779): WARNING **: 01:56:08.049: Failed to create IPv6 XDMCP socket: Unable to create socket: Address family not supported by protocol

** (lightdm:580779): WARNING **: 01:56:08.050: Error getting user list from org.freedesktop.Accounts: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Accounts was not provided by any .service files
Failed to use bus name org.freedesktop.DisplayManager, do you have appropriate permissions?

I am looking for a way to run a second x-server with another user
(authenticated or not)

It is not a problem to run an xterm using ssh -X in it.

Similar problem for using xfce4-session:

$ DISPLAY=:7 xfce4-session
xfce4-session: Another session manager is already running

And also using startxfce4:

$ DISPLAY=:7 startxfce4
/usr/bin/startxfce4: X server already running on display :7
xfce4-session: Another session manager is already running

Any help would be great!

What if you were to ctrl-F2 and login as a second user the startxfce4 :1

Hello!

Thanks, but what I need is this session running just in a window (including, second step probably,
enabling cu&paste and sound).
Using

pkexec -u OtherUser bash -c 'DISPLAY=:5 startxfce4'

it works (and as I expected: no sound (like fast userswitching) and no cut&paste).
Its probably mostly a matter of systematic documentation, but I am not
finding somethings about it.

Thanks for your response!
