我刚刚安装了Linux Mint 14，但无法更改屏幕分辨率。适当的分辨率1920 x 1200，只是不在选项之列。

我尝试过此解决方案，但报告：

xrandr: cannot find output "VGA1"

我也尝试过此方法，但报告：

Fatal server error:

Server is already active for display 0

If this server is no longer running, remove /tmp/.X0-lock

and start again.

在终端输出中运行xrandr命令：

DVI-I-1 disconnected (normal left inverted right x axis y axis)

这没有安装nvidia驱动程序。

执行命令后， xrandr --newmode "1920x1200_60.00" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync它将报告：

当我从此处运行尝试解决方案时sudo Xorg -configure，我得到：

Fatal server error:

Server is already active for display 0

If this server is no longer running, remove /tmp/.X0-lock

and start again.
