Ubuntu 12.10 - 如何在系统启动时使用命令行将分辨率设置为 1024x768 和正确的速率？

我有以下代码，其中我的 VGA 输出总是显示超出范围。我该如何解决？

$ cvt 1024 768
$ xrandr --newmode shvga 74.50 1024 1072 1176 1328  768 771 775 798
$ xrandr --addmode VGA-1 shvga
$ xrandr --output VGA-1 --mode shvga

我还应用了 xrandr --output VGA-1 --mode shvga --rate 60 或 70，但都无济于事。有永久的解决方案吗？

另一方面我还有另一个屏幕

    echo "[resolution]: trying 720p"
    export DISPLAY=:0.0 && cvt 1280 720 70
    export DISPLAY=:0.0 && xrandr --newmode legend 74.50  1280 1344 1472 1664  720 723 728 748
    export DISPLAY=:0.0 && xrandr --addmode HDMI-1 legend
    export DISPLAY=:0.0 && xrandr --output HDMI-1 --mode legend
    export DISPLAY=:0.0 && xrandr --addmode HDMI-2 legend
    export DISPLAY=:0.0 && xrandr --output HDMI-2 --mode legend

这给了我：
