我正在vmware 4.0播放器上运行ubuntu 11.10。我有问题，希望你能帮我。
当我登录到启动屏幕时，ubuntu会拿走我的密码，但会立即将我返回到启动屏幕。这种情况只发生在1个用户身上（另一个用户登录良好）。当我使用F1登录时，我能够成功登录（注意：它会抛出一个错误"export:29:：bad variable name"）。
我尝试过：删除.config/gnome会话目录，并修改/tmp上的权限（sudo-chmod-Ra+w/tmp），如下所述：http://ubuntuforums.org/showthread.php?t=1139558&page=3（我知道这是错误的版本，但值得一试。）
我还尝试了Alt+SysRq+R+S+E+I+U+B，如下所述：http://www.botskool.com/forum/computer-programming/linuxunix/restartshutdown-frozen-linuxubuntu
最后，我删除了.Xsession并安装了libglib2.0，如下所述：https://askubuntu.com/questions/81147/endless-login-loop
有其他建议或资源需要检查吗？TIA，
Joe

您是否修改了主文件夹中的默认.bashrc？就像一个"高管什么的"？
我知道这听起来很奇怪，但我也遇到了类似的问题，尽管我使用的是KDE而不是gnome。
顺便问一下，你能把你的.bashrc发出来吗？尤其是第25至35行。
