XDMCP登录失败

[kelvinwu_2008]

查了相当多的资料，在ubuntu8.1上开启XDMCP服务，都不成功，表现为当别的机器通过网络连接该XDMCP服务时，只有黑色背景和一个叉鼠标，没有登录对话框。有谁在8.1上设定XDMCP成功过？

是这个效果吗

我在本机可以用另外的帐号再登录一次本机

对，就是这个。楼上的朋友是怎么开通本机的XDMCP的，你的是8.1的版本吗？我的只有一个背景与叉。

效果如下图所示，连上去后一直保持这个画面。

我的配置过程：

在“系统”－“系统管理”－“登录窗口”，把远程打开，XDMCP的配置默认，配置完以后应该就可以了。

可以在/etc/gdm/gdm.conf-custom里面可以看见已经打开远程连接了

代码： 全选

[xdmcp]

Enable=true

本机这个时候应该开放了udp177端口，连接成功后会开放tcp6000端口

代码： 全选

udp        0      0 0.0.0.0:177             0.0.0.0:*

搞到我使劲改gdm.conf

原来要改gdm.conf-custom才行的。
这里贴下gdm.conf-custom文件内容，他的说明挺奇怪的。注意红色的部分
kelvin@fortest:~$ cat /etc/gdm/gdm.conf-custom
# GDM Configuration Customization file.
#
# This file is the appropriate place for specifying your customizations to the
# GDM configuration. If you run gdmsetup, it will automatically edit this
# file for you and will cause the daemon and any running GDM GUI programs to
# automatically update with the new configuration. Not all configuration
# options are supported by gdmsetup, so to modify some values it may be
# necessary to modify this file directly by hand.
#
# Older versions of GDM used the "gdm.conf" file for configuration. If your
# system has an old gdm.conf file on the system, it will be used instead of
# this file - so changes made to this file will not take effect. Consider
# migrating your configuration to this file and removing the gdm.conf file.
#
# To hand-edit this file, simply add or modify the key=value combination in
# the appropriate section in the template below. Refer to the comments in the
# /usr/share/gdm/defaults.conf file for information about each option. Also
# refer to the reference documentation.
#
# If you hand edit a GDM configuration file, you should run the following
# command to get the GDM daemon to notice the change. Any running GDM GUI
# programs will also be notified to update with the new configuration.
#
# gdmflexiserver --command="UPDATE_CONFIG <configuration key>"
#
# e.g, the "Enable" key in the "[debug]" section would be "debug/Enable".
#
# You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and
# re-read the new configuration settings. You can also restart GDM by sending
# a HUP or USR1 signal to the daemon. HUP behaves like gdm-restart and causes
# any user session started by GDM to exit immediately while USR1 behaves like
# gdm-safe-restart and will wait until all users log out before restarting GDM.
#
# For full reference documentation see the gnome help browser under
# GNOME|System category. You can also find the docs in HTML form on
# http://www.gnome.org/projects/gdm/
#
# NOTE: Lines that begin with "#" are considered comments.
#
# Have fun!

设置成功了吗？只是需要修改这一个地方吗

设置成功了吗？只是需要修改这一个地方吗

改那地方后，改一下登录相关的设置就OK了。
