Ubuntu 14.4 无法登陆图形界面

简单描述一下就是所有用户（包括guest）都不能登陆图形界面，输完密码后闪一下回到登陆界面（密码没错），登陆命令行没有什么问题。
搜了很多答案，大多和下面的文件有关，这里描述一下。

**貌似#开头的各行字体都很大，下面注释部分的# 换成了 /* # / *

~/.Xauthority权限也没什么问题，不是root
~/.xsession-errors文件没有任何内容，
~/.bashrc已删，直接从/etc/skel/拷了一个过来
/etc/environment在发生以上错误的时候只有一句，PATH= .../usr/bin.../sbin...bin
具体内容不太记得了，网上有说这个文件可以没有，删了说不定能解决问题，已删，还是登不上。。

~/.dmrc 内容如下
[Desktop]
Session=xubuntu

/etc/profile内容如下
