两台笔记本电脑都从 14.04 升级到了 16.04（我更喜欢开源驱动程序，因为它支持第二个 USB 显卡）哪里可能出现问题？

答案1

看起来你的 xrandr 语法错误，你也不需要使用 sudo 运行它。

首先介绍 xrandr 的模式

xrandr --newmode 1920x1080_60 173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

然后将其分配给相关输出（例如 hdmi、dp1、vga）

xrandr --addmode HDMI1 1920x1080_60

然后让输出使用新的分辨率

xrandr --output HDMI1 --mode 1920x1080_60

这是一个相当标准的分辨率，所以我很惊讶你实际上需要这样做，这表明你的显示器没有正确地宣传其功能，或者你的显卡驱动程序不太理想。
