HDMI 连接消失

HDMI 连接消失

我使用的是东芝笔记本电脑,在英特尔图形控制器上运行 Ubuntu 12.04,通过 HDMI 连接到飞利浦显示器。有一天,联系(更不用说显示器了)通过 HDMI 就消失了。我之前也遇到过同样的问题,通过更新解决了这个问题(就像这个家伙的如何使用 xrandr 检测和配置输出?)。那天我记录了自己运行的更新,但好像没有任何图形更新。这似乎是系统问题,所以我想一劳永逸地解决它。

提前谢谢!如果您需要更多详细信息,请告诉我。

我试过:

  1. 重启
  2. sudo apt-get upgrade && sudo apt-get update
  3. 重新连接

xrandr 的输出:
