Ok it's an ipv6 issue... I have to blacklist the ipv6 module on the 'server' to make it works. It seems that gdm try to connect in ipv4 (/usr/bin/Xnest :20 -br -br -audit 0 -name Xnest -auth /tmp/.gdmQRU2JT -terminate -query 192.168.1.133 -fp /usr/share/fonts/X11/misc,/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType,/usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/100dpi/,/usr/share/fonts/X11/75dpi/ -display :0)
but the connection is made in v6 (according to wireshark) ** Tags added: ipv6 -- XDMCP not working https://launchpad.net/bugs/75254 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
