![双显示器不工作,白色背景](https://linux22.com/image/828368/%E5%8F%8C%E6%98%BE%E7%A4%BA%E5%99%A8%E4%B8%8D%E5%B7%A5%E4%BD%9C%EF%BC%8C%E7%99%BD%E8%89%B2%E8%83%8C%E6%99%AF.png)
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:

Screen "amdcccle-Screen[1]-1" 1920 0

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。
