我已经将此报告为错误（https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1272621）但我认为这可能对其他用户有用，所以我认为我应该在这里请求修复。
我在华硕 F201E 上使用 Ubuntu 13.10 64 位，当我通过 VGA 插入我的 Acer x233h 作为外接显示器时，“系统设置 > 屏幕显示”中可用的最大分辨率是 1024×768（以及 800×600），但屏幕的最大分辨率应该是 1920×1080。
我在“系统设置 > 软件和更新 > 附加驱动程序”中没有可用的专有驱动程序，并且我安装了最新版本的英特尔 Linux 显卡驱动程序https://01.org/linuxgraphics/downloads，以为它会有所帮助（版本 1.0.3），但无济于事。
这似乎不应该是默认行为。任何帮助都将不胜感激，因为这个外接显示器的最大分辨率最终不如我的小笔记本电脑……:)

答案1
关于您缺少的分辨率，遇到该问题后，请尝试重新启动并保持显示器连接。有时有用。
如果失败，请尝试关闭连接显示器的笔记本电脑盖子；或许它会假定您的显示器现在是主显示器并让您使用全分辨率。
祝你好运 ：）
