[Bug 75254] Re: XDMCP not working

[Laurent Bigonville]

I've recompiled with --enable-ipv6=yes, same problem...

In fact the negotiation is made in ipv4 (xdmcp port) and the export
display is made in v6

If I change the -query option to the server ipv6 address, the screen
stay black, with wireshark I see that the server doesn't event open his
xdmcp port in v6 to negotiate the connection.

XDMCP not working in ipv6, gdm should be compiled with --enable-ipv6=yes
