我没有使用glx-new，而是直接去nvidia下了驱动包回来。也装好了，但是却不能切换用户，注销以后无法重新登录X桌面，整个屏幕都是黄色的，只有左上角有一块灰色，然后鼠标挪上去变成'I"字型，但是除此以外没有任何反应了，除非按Ctrl+Alt+Fx切换在终端，或者按Ctrl+Alt+BS登出。必须重启电脑才可以，请问是什么原因？怎么解决这个问题呢？？
晕……换用了nvidia-config生成的conf还是不行……照样无法切换用户。
发现一个新的现象：点击“切换用户”以后的确没反应，但是这时运行任何程序，都不会弹窗口出来，但是系统管理器里面明明可以看到它们的进程。我开始按组合键准备调一个终端出来，结果没出来，我按了很多下都没出来，后来在系统管理器里面发现了一大堆终端，可就是没有显示………………
顺便问一下，如果我删掉了home和etc里面所有的配置文件，会不会再自动给我生成呢？如果还不行我就准备实验一下了，反正最后不行我就重装Ubuntu……
我的xorg.conf:
