你是否还在为升级后普通用户进不了x发愁？是否出现/dev/null的权限不够？请看这里！

归根结底是升级udev惹的祸
所以有两种解决方案 ：
一：给udev降级；
二：etc-update;
但是etc-update要升级的实在是都
所以我们使用：

1. genlop -t udev

复制代码

1. * sys-fs/udev
   
2. 
   
3.      Sat Mar 12 02:31:47 2005 >>> sys-fs/udev-045
   
4.        merge time: 11 seconds.
   
5. 
   
6.      Wed Jun  8 16:48:11 2005 >>> sys-fs/udev-058
   
7.        merge time: 54 seconds.

复制代码

1. emerge =udev-045

复制代码

然后重启，问题解决！

我是先emerge -C udev,然后把/etc/udev目录删除干净然后重新emerge udev,一切正常，就是不知这样是否有什么不妥？

楼上的办法应该也行

pongo

我是切到控制台，
chmod a+w /dev/null
硬盘一响，进去了

chmod  不是根治的办法，你重启看看，重启以后问题依旧.
