我的教室里有一台电脑，它连接到一台 LG 智能电视（其实它并不那么智能。我不建议购买。）。对于触摸界面，电视需要 1920x1080 的分辨率，频率为 60Hz。但是，我似乎无法将电脑设置为该分辨率。显示设置仅提供 1024x768 和 640x480。
计算机与 Windows XP 双启动，其中宽屏选项可提供大约所需的尺寸，但精确的分辨率——甚至是纵横比——在 XP 中也不可用。
我尝试了以下命令：
xrandr -s 1920x1080 -r 60
答复是：
在可用模式下未找到尺寸 1920x1080
在过去，解决方案是编辑xorg.conf。但是，由于该文件不再存在，而且我找不到最新信息，所以我不知道还能做什么。如果有帮助的话，这台机器将永远不会连接到不同的显示器，因此分辨率灵活性并不重要。
以下是 的输出lshw：

根据系统设置，我的图形驱动程序是未知的，并且我的“体验”是标准的。
这是 64 位 Ubuntu 12.04 (Precise)
笔记：有许多与此类似的问题，但它们没有提供任何对我有帮助的答案。

在发布这个问题后，我注意到一个在侧边栏我通过搜索没有找到它，但它似乎包含答案。基于这个问题，我创建了/etc/X11/xorg.conf下面的文件：

根据/var/log/Xorg.0.log，我的设置没有被应用。事实上，我怀疑配置文件是否被读取。
