从 11.10 升级到 12.04 beta 后，我收到以下错误。即使每天更新补丁，问题仍未解决，因此我将其发布出来。
Ubuntu 12.04 beta Compiz 错误：Fatal: couldn't open display :0
基本上：当我启动时，屏幕会短暂显示 Ubuntu 加载，持续几秒钟，然后转到终端登录屏幕。
我有一张 ATI 卡，以前在 11.10 上安装了我自己编译的驱动程序，不确定升级是否覆盖了它。
更新
当尝试安装fglrx驱动程序时，我收到类似这样的错误：（我无法在控制台中截屏或复制粘贴，因此我在另一台计算机上写出它：
dpkg: 处理 /var/cache/apt/archives/fglrx_2%3a8.960-0ubuntu1_amd64.deb (--unpack) 时出错：
子进程错误状态 1
