[已解决]16.04， 强制重启一次开机之后总是自动注销

[comero]

Unity 桌面环境
在一次估计内存占用过高(大概是因为网页开的太多了。。)
太卡之后强制重启了一下，开机就这样了，大约20s，就黑一下注销等待密码输入(这20s之内没啥异样)。
看了一下syslog,我复制不出来，不好意思只能贴一下图了


求助一下 T T
我想问题应该在client connected 和 disconnected之间，但却是没什么内容。。 需要多一点我可以再拍点。。

这个可能清楚一点

用ssh登陆复制了一些

复制了一部分syslog出来。

最新一次开机syslog全记录， 20s无操作。
我自己也研究一下。。

看看 ~/.ICEauthority 的权限所有者。正常应该是 -rw------- 1 你的用户 你的用户
看看 ~/.xsession-errors，最好一登录马上 tail -f ~/.xsession-errors，看看“大约20s，就黑一下”之前有什么信息
看看 /var/log/Xorg.0.log.old （上一个 Xsession 的日志。大约20s，就黑一下注销等待密码输入，Xorg 重启了，所以要看上一次的日志末尾部分）

感谢~~
.Xauthority 权限正常

~/.xsession-errors 仅有 这个错误： cannot connect to brltty at :0
尝试了一下 mv ~/.config/dconf/user ~/.config/dconf/user.old ，没啥用 XD
/var/log/Xorg.0.log.old 这个我看了一遍 只有Warning， ( 内容 http://paste.ubuntu.com/25407843/)

有点像这个描述-- 登陆界面循环(不过起码我进去了 ...)
http://bbs.csdn.net/topics/391874698[求教：Ubuntu 14.04升级到16.04在登陆界面循环不能进入桌面怎么办？]
感觉很多都指向 nvidia驱动 我想应该试试吧
不过在此之前再搜搜看，感觉看到更多类似问题了 XD

按照这个看了看用户目录权限, 竟然是 555！ O_o
http://tieba.baidu.com/p/3347036013 [求助！ubuntu无法进入图形界面]
我改成755,以及删掉了 .Xauthority ( 不过 .ICEauthority 和 .Xauthority 的区别我得去看看，我自然而然的一直在关注Xauthority XD )
突破了20s！T T
万分感谢，本来真是一筹莫展以至于睡了一会orz！
