将屏幕分辨率更改为真实分辨率选项不可用

我最近在安装全新安装的 Ubuntu 12.04 后通过软件更新进行了更新，我的屏幕分辨率完全乱了。目前的默认屏幕分辨率是：

1600 x 1200 (4:3) -- Using this now and it is quite hard to see the screen considering there is no HDMI, just VGA
1280 x 1024 (5:4)
1024 x 768 (4:3) -- Unusable as when I select it, I get a "Fuzzy" screen
800 x 600 (4:3)

我已进入xorg.conf文件并确保我的vertRefresh和horizontal Sync全部正常且符合显示器制造商的规定。这并没有改变任何事情。我还尝试添加 1366x768 的元模式和模式，但仍然没有奏效。

这是我当前的 xorg.conf 文件：

我也尝试使用 xrandr 将分辨率设置为 1366 x 768，但没有成功。有什么方法可以让我的分辨率恢复正常吗？谢谢！

您确定您的显卡拥有正确且最新的驱动程序吗？

检查是否可以更新驱动程序。
