运行 Mint 17.1 和 Cinammon 2.4.8，我有两个 2560 * 1440 显示器，两个显示器都放置在显示设置中，彼此相邻，而不是镜像。
鼠标光标在两个显示器之间正常移动，但左显示器右侧顶部和底部的约 16 个像素除外。然后，光标将不会再向右移动，直到我将其移动到距离屏幕顶部或底部超过 16 个像素为止。
这大约是面板或标题栏的高度，所以我的第一个想法是关闭所有应用程序并在空桌面上尝试。仍然发生。与从底部移动任务栏面板相同。
我也尝试过更换显示器，但它仍然发生。即使设置显示偏移，例如，光标从左屏幕的中间移动到右屏幕的顶部，反之亦然，也没有效果；光标仍然卡在左屏幕顶部和底部 16 像素处。

答案1
我知道这有点旧了，但是 Cinnamon 面板设置中有一个选项可以“允许指针穿过面板的边缘”。默认情况下禁用此功能。这可能是你的问题。
我运行 17.1 已经有一段时间了，我的屏幕截图来自 18.3，但我很确定该选项仍然存在于某处。
答案2
这看起来像是屏幕具有不同的分辨率，特别是左边的屏幕比右边的屏幕更高并且延伸得更高和更低。xdpyinfo可以验证或反驳这一点。
