最近我在以下设备上安装了 14.04：
- 华硕 A88XM-A 主板
- AMD A10 7700K 处理器
- 32G 内存。
内核版本为： - 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
我的视频连接是通过 MoBo 的集成视频连接（而不是单独的视频卡）。我的 HDMI Monitory 是 SAMSUNG 27 SyncMaster。昨天我购买了 Benq sensey 27，现在使用单链路电缆连接到 DVI-D。
问题是两个显示器都是镜像的。显示器只显示一个显示器为粉红色（内置显示器），内置显示器下方为粉红色，开/关开关为灰色并设置为开启。镜像显示器也为灰色，似乎未选中。分辨率为 1920x1080(16:9)，启动器位置为所有显示器。
单击“检测显示器”时没有任何反应。请帮助我了解如何在双显示器配置中关闭镜像。
我真的不知道我在找她什么，但在/var/log/Xorg.0.log这看起来很有趣：

答案1
你需要切换到 2D 模式 对我来说很好用
