====卸载掉昨天最后安装的ubuntu tweak============

安装lightgdm和gdm：

=============是没有lightdm的原因么？==========================

lightdm应该是存在的吧。

http://askubuntu.com/questions/172861/ubuntu-12-04-logins-to-tty1-instead-of-regular-login-screen-cant-start-lightdm

sudo apt-get remove lightdmsudo apt-get install lightdm.

If that doesn't work try sudo start lightdm.

If that doesn't work than I don't know.

==========================是因为没有gdm么？=========================

我的gdm却是被我删掉了。

使用默认的lightdm

重新安装下？

=======但还是会卡在这里=================

startx，进入系统，这个时候界面是u界面，不是gnome的：

可见，问题出在修改的一个启动的脚本上：

正确的是不修改，用原来默认的：

昨天按照这个修改的，所以无法进入界面，卡在tty1的字符界面上：

正确的选择登陆界面的方法是：

我现在运行fcitx的界面是gnome classic （no effect ）

If you can't start GDM, simply make it the default and reboot.

Code:

    sudo apt-get install gdm    sudo dpkg-reconfigure gdm    sudo reboot

The second command above will give you a colorful screen where you choose between lightdm and gdm. Choose gdm, press enter. Then use the last command to reboot.

To find out what went wrong, have a look at your log files:

Code:

sudo less /var/log/lightdm/x-0-greeter.logsudo less /var/log/lightdm/lightdm.log
