ssh - remote applications and remote desktop

[beerstein]

Hi: SSH is pretty much straight forward but I still have two problems:
1. I am able to  ssh from Mint14 into TCL piCore5.1rc3 and start extensions such as mc (Midnight Commander), cpanel, apps, filetool, pcmanfm and dillo. I am not able to bring the piCore 5.1rc3 window manager flwm_topside onto my display at the mint15 machine.
here is what I did:
tc@box:~$ flwm_topside
Another window manager is running.  You must exit it before running flwm_topside.
Question: Which window manager is running here? The Mint14- or the piCore window manager?
How can I exit (stop) that window manager which is in my way here ?
This is not a piCore specific problem it applies to all TCLs.

When I ssh from piCore into my Mint14 the ssh connection works perfect. I can start all applications on the Mint14 machine and when I start the file manager nemo on the Mint14 machine I even get the desktop from Mint14 on TCL.
In all cases I only used the CLI command: $ ssh user@IP_address_remote_computer.
No -X and no -Y operators . I have X-forwarding as yes in both config files of openssl on both machines.

Any help is appreciated -  Thanks in advance.

The "WM already running" refers to your host, ie the Mint WM.

I wouldn't know how you would start a Mint session without a WM, perhaps that's a question to the Mint forums. On a simpler distro, you'd just comment out the host WM

thank you for this:
I can remote log in via ssh into Raspian wheeze from my Mint14 terminal. The RasperryPi Raspian must be in CLI.
After ssh -Y pi@IPaddress I am connected and then:
$ lxsession&
gives me the complete RasperryPi desktop on my Mint14 desktop. This is what I would like to do with Mint14 and piCore.
