找不到最佳屏幕分辨率

一周以来，我一直是 Ubuntu 用户。由于我的付费 XP 许可证不再受支持，因此我从 Windows 切换过来。我对 Ubuntu 非常满意，它运行完美！

只有一个小问题，那就是我的屏幕分辨率。我在 ubuntu 12.04 LTS 上使用 Iiyama ProLite E1902WSV 显示器

当我将代码xrandr放入终端时，我得到以下信息：

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768       60.0* 
   800x600        60.3     56.2  
   848x480        60.0  
   640x480        59.9  
DVI-D-1 disconnected (normal left inverted right x axis y axis)
TV-1 disconnected (normal left inverted right x axis y axis)

现在问题来了，因为我的 Iiyama 的最佳屏幕分辨率不在此列表中。我在网上查了一下，最佳分辨率应该是 1440x900 (来源）

有人知道如何解决这个问题吗？提前谢谢！

在得到 Sylvain Pineau 的解决方案后，我今天早上启动了电脑并收到了以下消息。

none of the selected modes were compatible with the possible modes:

这个问题也有解决办法吗？我的屏幕分辨率还是和一开始一样，1024x768 (4:3)...

答案1

首先尝试定义一个 VIRTUAL1 显示：

xrandr --newmode "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync

并用它来设置VGA-1：

xrandr --addmode VGA-1 1440x900_60.00
