登录tty，输入gdm敲回车，提示

**(gdm-binary:900):WARNING **: Failed to acquire org.gnome.DisplayManager:connection"1.11" is not allowed to the service "org.gnome.DisplayManager" due to security policies in the configuration file

**(gdm-binary:900):WARNING ** Could not acquire name;bailing out

查查xorg的log..

换源更新至xf86-video-ati 6.14.4-2搞定

A卡伤不起！

我才挂了，每次装完重启/dev文件夹都是空白的。
