![Ubuntu 18.04 LTS 的 VGA 屏幕模糊](https://linux22.com/image/911282/Ubuntu%2018.04%20LTS%20%E7%9A%84%20VGA%20%E5%B1%8F%E5%B9%95%E6%A8%A1%E7%B3%8A%20.png)
我有双显示器,一个通过 HDMI 连接,另一个使用 VGA。第二台显示器上的图像很模糊,我使用以下脚本来设置分辨率:
#!/bin/sh
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode DP-1 1920x1080_60.00
在我的配置中,VGA 上的监视器被称为“DP-1”。

答案1
我找到了解决办法:使用合适的 VGA 线。我一直使用廉价投影仪自带的 VGA 线。当我从同事那里借了 VGA 线后,问题就解决了。
