关于昨天提问的修改了登录选项导致不能进入登录界面--[已解决]

[casio1374633]

现在我在网络查了一些情况，似乎比较明朗了。

我是ubuntu和kubuntu共存，用gdm登录，然后在gnome下面使用了“系统－系统管理－登出窗口－辅助功能－启用辅助功能登录”的那个选项我勾选了。在百度下面搜到为在6.10下面的确出现了不能登录的情况，说明不是个例。但是都没有给出如果已经不能登录该如何解决的办法，只是说这是一个bug，并且提醒不要勾选此项。
用百度搜于“ubuntu 辅助功能登录”
http://www.baidu.com/s?ie=gb2312&bs=%C6 ... C2%BC&ct=0

可以看到相关信息，不过我现在已经勾选并且进入不了登录界面了。不过可以使用tty，我请问我该如何解决此问题，修改哪个文件可以搞定？

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

现在有一个更好的消息就是可以通过选择recovery mode，然后startx用root身份进入x-windows（gnome下面）
不过尝试修改回登录选项，弹出对话框为现在不是gdm登录，所以不能修改。。所以不知道各位大侠，有没有解决的办法。。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

再补充一部分。。现在我进入系统X了。。但是方式是，先通过liveCD恢复整个／TMP文件夹，接着从起，先进入tty，然后删除了／tmp／.X0－Lock文件，然后才startx的。不过问题是只要进行登录窗口的选项操作就会回到原来的样子。。请各位帮忙啊～～


～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

现在轻松多了。。因为问题解决了。。呵呵。。。

在搜索过程中看到其实在ubuntu论坛早些时候也有人提问这个问题，一共从百度搜索到了2次。但是很可惜的都是没有人回帖，最后也不了了之了。。

可以证明的是，选项，启动辅助登录是个bug。
我在自己查看文件时候注意到了那个addGTK..=true
我接着使用百度搜索此项目，的确，默认为false，于是我改了过来。其实就是这么一个小小的改动。呵呵。。


需要修改的文件位置:sudo gedit /etc/gdm/gdm.conf-custom
文件最下面开始往上找:
[daemon]
GtkModulesList=gail:atk-bridge:/usr/lib/gtk-2.0/modules/libkeymouselistener:/usr/lib/gtk-2.0/modules/libdwellmouselistener
AddGtkModules=true<---(此处改成false,从起就ok)

zmcbb30兄。

就像我认为的。其实就是得了个感冒发烧什么的。别一下子就判成癌症了。。

还有：也许在你眼里我这算是瞎掰吧。天真吧。幼稚吧。但是我很快乐。我可以肯定，在以后如果有兄弟在不小心做了同样的修改并中招以后，他不需要通过从装整个系统而苦恼，因为他可能和你的分区模式一样，只有/和swap,然后需要需要tar整个home备份自己的重要文件,接着是估计需要30分种的从装和估计几个小时的升级+安装附加软件，但是现在他只需要修改一个文件的一个单词而已。至少他可以在百度里面或者在本论坛得到解决方法。

现在，我至少还了解了gdm配置文件的所在位置，和基本分布情况。

在这里，我还是愿意强调linux的最大不同就是，它不是什么最优秀的操作系统，但是他提供了最开心的解决方式和讨论模式。倒是在win下面，不少看似很厉害的人经常烦躁的对新手的提问说，你从装吧，ghost吧。。怎么瞎掰啊。。怎么不装杀毒软件啊。怎么不用正版啊。

难道没人回帖？！至少说点什么啊

自我再做个补充。想到了自己搜索gdm配置文件

路径如下：
/etc/gdm/factory-gdm.conf和/etc/gdm/gdm.conf-custom这两个文件

我的factory-gdm.conf为

代码： 全选

# GDM System Defaults Configuration file.
#
# This file should not be updated by hand.  Since GDM 2.13.0.4, configuration
# choices in the GDM Custom Configuration file will override the default
# values specified in this file.  This GDM System Defaults Configuration file
# may be overwritten on upgrade, so to ensure that your configuration choices
# are not lost, please make sure that your changes are made only the GDM Custom 
# Configuration file.  The GDM Custom Configuration file is found at the
# following location:
#
# /etc/gdm/gdm.conf-custom
#
# If you were using an older version of GDM, your system may have the the older
# gdm.conf configuration file on the system.  If so, then this file is used
# instead of the GDM Custom Configuration file for backwards support.  If you
# make changes to the GDM Custom Configuration file and they seem to not be
# taking effect, this is likely the problem.  Consider migrating your
# configuration to the new configuration file and removing the gdm.conf file.
#
# You can use the gdmsetup program to graphically edit the gdm.conf-custom
# file.  Note that gdmsetup does not support every option in this file, just
# the most common ones that users want to change.  If you feel that gdmsetup
# should support additional configuration options, please file a bug report at
# http://bugzilla.gnome.org/.
#
# If you hand-edit the GDM configuration, you should run the following command
# to get the GDM daemon to recognize 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/

# It is an IPv6 multicast address.It is hardcoded here and will be replaced
# when officially registered xdmcp multicast address of TBD will be available.
#Multicast_Addr=ff02::1
# Allow adding random hosts to the list by typing in their names.
#AllowAdd=true

[debug]
# This will cause GDM to send debugging information to the system log, which 
# will create a LOT of output.  It is not recommended to turn this on for
# normal use, but it can be useful to determine the cause when GDM is not
# working properly.
Enable=false
# This will enable debug messages for accessibilty gesture listeners into the
# syslog.  This includes output about key events, mouse button events, and
# pointer motion events.  This is useful for figuring out the cause of why the
# gesture listeners may not be working, but is too verbose for general debug.
Gestures=false

[servers]
# These are the standard servers.  You can add as many you want here and they
# will always be started.  Each line must start with a unique number and that
# will be the display number of that server.  Usually just the 0 server is
# used.
0=Standard
#1=Standard
# Note the VTAllocation and FirstVT keys on Linux and FreeBSD.  Don't add any
# vt<number> arguments if VTAllocation is on, and set FirstVT to be the first
# vt available that your gettys don't grab (gettys are usually dumb and grab
# even a vt that has already been taken).  Using 7 will work pretty much for
# all Linux distributions.  VTAllocation is not currently implemented on
# anything but Linux and FreeBSD.  Feel free to send patches.  X servers will
# just not get any extra arguments then.
#
# If you want to run an X terminal you could add an X server such as this:
#0=Terminal -query serverhostname
# or for a chooser (optionally serverhostname could be localhost):
#0=Terminal -indirect serverhostname
#
# If you wish to run the XDMCP chooser on the local display use the following
# line
#0=Chooser

## Note:
# is your X server not listening to TCP requests?  Perhaps you should look at
# the security/DisallowTCP setting!

# Definition of the standard X server.
[server-Standard]
name=Standard server
command=/usr/X11R6/bin/X -br -audit 0 
flexible=true
# Indicates that the X server should be started at a different process
# priority.  Values can be any integer value accepted by the setpriority C
# library function (normally between -20 and 20) with 0 being the default. For
# highly interactive applications, -5 yields good responsiveness. The default
# value is 0 and the setpriority function is not called if the value is 0.

#priority=0

# To use this server type you should add -query host or -indirect host to the
# command line.
[server-Terminal]
name=Terminal server
# Add -terminate to make things behave more nicely
command=/usr/X11R6/bin/X -br -audit 0 -terminate
# Make this not appear in the flexible servers (we need extra params anyway,
# and terminate would be bad for xdmcp choosing).  You can make a terminal
# server flexible, but not with an indirect query.  If you need flexible
# indirect query server, then you must get rid of the -terminate and the only
# way to kill the flexible server will then be by Ctrl-Alt-Backspace.
flexible=false
# Not local, we do not handle the logins for this X server.
handled=false

# To use this server type you should add -query host or -indirect host to the
# command line.
[server-Chooser]
name=Chooser server
command=/usr/X11R6/bin/X -br -audit 0
# Make this not appear in the flexible servers for now, but if you wish to
# allow a chooser server then make this true.  This is the only way to make a
# flexible chooser server that behaves nicely.
flexible=false
# Run the chooser instead of the greeter.  When the user chooses a machine they
# will get this same server but run with "-terminate -query hostname".
chooser=true

[customcommand]
# This section allows you specify up to 10 custom commands. Each of the
# commands can be defined by the seven parameters listed below. In each of the
# descriptions of the parameters N can take on any values between 0 and 9,
# i.e. CustomCommand0=,CustomCommand1=,...,CustomCommand9=.  The  numbers
# can have gaps as long as they fit within predefined set of 10, and their
# placement order within this section and with respect to each other is
# not important.
#
# CustomCommandN, CustomCommandTextN, CustomCommandLabelN, 
# CustomCommandLRLabelN, CustomCommandTooltipN, CustomCommandIsPersistentN
# and CustomCommandNoRestartN should all be defined for a given integer N, 
# where N can be a number from 0-9 (if not the default values will be 
# assigned except CustomCommandN for which no default exists).

# Custom command to run.  Multiple commands may be specified separated by 
# semicolons.  GDM will use the first valid command.  Examples:
# /sbin/bootwindoze;/usr/bin/bootwindoze, or
# /sbin/runupdate;/usr/local/sbin/runupdate
#
#CustomCommandN=

# Custom command dialog message that will appear on all warning dialogs.
# This will vary depending on what you want to do. Examples:
# Are you sure you want to restart system into Windoze?, or
# Are you sure you want do do this?
#CustomCommandTextN=

# Custom command label that will appear as stock label on buttons/menu items.
# This option can't contain any semicolon characters (i.e. ";").
# Examples:
# _Windoze, or
# _Update Me
#CustomCommandLabelN=

# Custom command label that will appear as stock label on radio buttons/list
# items.  The underscore indicates the mnemonic used with this item.  Examples:
#   Restart into _Windoze
#   Perform system _Update
#CustomCommandLRLabelN=

# Custom command tooltip. Examples
# Restarts the computer into Windoze
# Updates the computer software to the most recent version(s)
#CustomCommandTooltipN=

# Custom command persistence option. Setting it to true will allow this
# command to appear outside the login manager, e.g. on the desktop through 
# Log Out/Shut Down dialogs. The default value is false.
#CustomCommandIsPersistentN=

# Custom command gdm/system restart option. Setting it to true will not
# restart gdm after command execution.  The default commands (reboot, shut
# down) all reboot the system by default which is why the default setting
# is true.
# In addition when corresponding CustomCommandIsPersistentN option is set to
# true, setting CustomCommandNoRestartN to false will place CustomCommandN
# in the Shut Down dialog set of actions, setting it to true will place
# CustomCommandN in the Log Out dialog set of actions.
#CustomCommandNoRestartN=
#
# Example layout for more than one command:
#CustomCommand0=

gdm.conf-custom文件为：

代码： 全选

# 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/

我的问题是:
我修改了用户文件的路径
原来LJB用户的配置文件保存在\HOME\LJB里,
我直接在用户和组里面把它改为\ROOT\LJB了,
结果启动的时候,用LJB登录,说找不到配置文件,尝试在HOME里找,但随后又提示HOME里的文件没有权限读取吧,

现在就是进不了系统,
我用LIVE CD进去后,不知道怎么弄才能改回来?
可以的HOME下面看到LJB这个包,
但在用户组里面去找不到LJB这个用户,我添加新用户又不起作用,
应该如何操作?
对了,ROOT登录没有开户

我进行了和楼主一样的操作，出现了一样的问题，鼠标在那里转圈，gdm不能登录，最后在google上以gdm和登录窗口为关键词搜索，在linuxsir的论坛上看到了楼主的帖子，才解决了。

感想：如果是用于日常使用的系统，在不知道自己在进行什么操作的情况下，就不要操作了，也不要去试用那些无关紧要的功能，比方说这个登录声音，毕竟系统是复杂的，时间是宝贵的；如果是用于折腾，除外。

但折腾也有折腾的方法，可以事半功倍，也可以事倍功半，自己的教训：再也不从自己根本不懂的顶层和图形界面去折腾了，比如各种linux发行版和各种窗口管理器，老老实实、谨小慎微的使用就是，毕竟linux是从服务器而来，进行自己并不了解的配置是会搞瘫系统的，有问题，等着官方去解决吧；另一方面，从c语言、shell编程、lfs文档、gnu工具和常用软件的配置文件入手，去学习和了解linux系统。

最后：确认gdm的辅助登录选项是个bug，我用的窗口管理器是feisty下的xfce(LinuxMint)，也出了这个问题，最好是向ubuntu官方报告bug；谢谢楼主的帖子为我们澄清了这个问题，在解决之前，我一直是以recovery模式开机，直接执行startx，启用xwindow，绕过了gdm，所以还有一个建议：如果出了问题，宁愿忍受，也不要逃避（重装），但一定要善用google。
