[Wine] Multiple Instances of Diablo 2

[blawa]

Hi all,
I'm currently trying to run multiple Diablo 2 Windows with 1 user.
Thats what i managed to do until now:
if I use export WINEPREFIX=~/.wine2 and then run a copied d2, it works to join bnet twice, but when both are in the same game, 1 will get a Timeout.

So i tried to find a sloution (and found one):
I made another user (called "d21") and installed D2 into his personal .wine folder.
Now when I can have both accounts in the same game without getting a timeout, but i have to switch between the users all the time.

So i thought i could start a console with my first account ("blawa") and use:
sudo -u d21 -i
So after i auth, I'm into d21's personal folder in that console.
But now when i try to use wine with D2.exe, I get the following Errors:

Now, can someone tell me what exactly this error means, and if there is a way to fix that?
To me, it looks like wine wants me to start a 2nd X-Server so that he has a Window-Manager. But isn't there a way to pass the X-Server from my first account to the console where the 2nd account is logged in?

I hope someone can help me,
