![Ubuntu 13.10 更新后无法检测到 HDMI](https://linux22.com/image/1118628/Ubuntu%2013.10%20%E6%9B%B4%E6%96%B0%E5%90%8E%E6%97%A0%E6%B3%95%E6%A3%80%E6%B5%8B%E5%88%B0%20HDMI.png)
我正在运行 Ubuntu 13.10,出于某种原因,当我重新启动计算机时,我的 HDMI 不再被识别。发生了什么事?我该如何解决这个问题?
这是我的输出lspci -v -s 00:02.0

HDMI 未断开连接,应读取。进入显示后,我没有看到第二个屏幕。我已经看到多个与此相关的问题跟踪,但尚未解决。

这看起来像是显卡问题,但我怀疑我之前会注意到这个问题,而不是现在。也许这与我重启之前进行的 ubuntu 更新有关???
下面我添加了我的主板的规格。我使用的是集成显卡。
