ubuntu 12.04 中出现双屏吗?

我正在使用 ubuntu 12.04,我的显卡是 ATI Radeon 5000。我无法使用双屏(扩展版)。我收到此错误http://i48.tinypic.com/o9341y.png

无法应用所选的显示器配置,CRTC 148 请求的位置/大小超出允许的限制:位置=(1280, 0)、>大小=(1280, 768)、最大值=(1440, 1440)

我尝试了所有显示设置,但没有作用。

系统设置的一些输出:

我将非常感激任何关于如何解决问题的建议。谢谢

实际上正试图在错误的地方修复这个问题,转到终端并输入 sudo amdcccle 它将打开一个 AMD 催化剂中心窗口,在那里您可以去显示,检查显示器的正确分辨率,然后重新启动。一切都会像魔法一样运转!

瞧!
