背景
我正在运行一个 3 屏设置，其中 2 个 1080p 屏幕一个在另一个之上，侧面有一个 1680x1050 的纵向屏幕。
问题
启动时，纵向屏幕未呈现在正确的高度。相反，它显示一个图像2432px 高。将鼠标移到屏幕边缘会导致其在此大图像内滚动。当屏幕分辨率设置为auto和明确设置为 时，都会发生此问题1680x1050。
如果在启动后，我将方向更改为不同的值，点击应用，将其恢复为rotate 90并再次应用问题已解决。
如果重新保存 xorg.conf 并将屏幕设置为横向，则计算机可以正常加载。
线索
当我单击Save to X Configuration Filenvidia 设置时，出现以下对话框。
多个 X 屏幕设置为使用绝对定位。虽然这样做是有效的，但一个或多个 X 屏幕可能（或可能变得）由于重叠和/或死区而无法访问。建议仅对第一个 X 屏幕使用绝对定位，对所有后续 X 屏幕使用相对定位。
我没有遇到死角。我无法找到将纵向显示器设置为相对定位的方法，尽管为辅助 1080p 屏幕（顶部屏幕）进行设置很容易。
截断 MetaMode 列表？
当前 X 服务器不支持较长的 MetaMode 字符串（大于 900 个字符）。截断 MetaMode 列表以使 MetaMode 字符串不超过 900 个字符，将导致只有前 28 个 MetaMode 写入 X 配置文件。
注意：将所有 MetaMode 写入 X 配置文件可能会导致解析错误并无法启动 X 服务器。
我的选项是truncate metamodes或write all metamodes。我选择write all metamodes。这似乎是导致我的问题的最可能原因，但我无法用谷歌找到任何解决方案。以下是我的 xorg.conf
