这个问题真把我搞的很头大了,我用的是ATi5400+集成显卡。装的是12.04 装完系统以后执行xrandr有发现两个显卡。安装完ati的闭源驱动以后就只能发现Ati的了,貌似集成的被自动屏蔽了。
我在命令行下面执行X -configure :1生成修改xorg.conf文件,并覆盖原有路径下的xorg.conf

重启计算机以后,提示The System is running in low-graphics mode. 如果我在Section "ServerLayout" 里面只保留screen 0 或者1,重启以后都能正常进入系统。这个问题已经让我抓狂了,有同学说在N卡下都正常,不知道大家有没有碰到这个问题。
