我刚刚安装了 Ubuntu，并使用 xrandr 将 1280x1024 添加到我的辅助显示器。当我这样做时，Ubuntu 将辅助屏幕显示在原来的左侧，这意味着我只能看到部分屏幕。
xrandr 的输出：

cvt 1280 1024 的输出：

然后我使用以下命令添加显示模式：
xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
xrandr --addmode DVI-I-1 "1280x1024_60.00"
然后我打开设置并选择分辨率。
我的显示现在如下所示： 显示器
我曾尝试从显示器本身改变位置，但这不足以将显示器置于正常位置。
我该如何让显示器恢复正常位置？谢谢！
答案1
我已经找到了如何在特定显示器上修复此问题的方法。我进入显示器设置，选择自动调整，这样屏幕就可以处于正确的位置，然后我调整垂直值以将显示设置在正确的位置。如果没有这些选项，这仍然无法在显示器上工作。
