双显示器不工作，白色背景

我的问题是，我的第二台显示器是白色的。我尝试过以下方法：系统设置 > 显示 > 启用显示。然后我得到：所需的虚拟尺寸不适合可用尺寸：请求=(3840, 1200)、最小=(320, 200)、最大=(1920, 1920)

我下载了最新的驱动程序和 CCC。然后我尝试使用 Catalyst Control Center 并在那里启用显示，然后重启后我得到的是白色显示。

我的驱动程序如下所示：

$ lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cayman XT [Radeon HD 6970]

我的 X11 xorg.conf 如下所示：

我过去曾通过以下方式成功解决过类似的问题。首先拔下第二个显示器并运行：

sudo aticonfig --initial

这将重新初始化您的 xorg.conf。现在重新启动您的机器。重新启动后，重新插入第二个显示器，运行

gksu amdcccle

并根据需要配置显示。请注意，如果您从仪表板运行 Catalyst 控制中心，它将没有 root 权限，并且无法将您的配置保存到 xorg.conf。
