我有一台装有 Deepin Linux 的 Dell XPS 台式机，但板载 HDMI 无法工作（无信号）。根据从 Ubuntu 收集的 Ubuntu，Deeping 未识别某些 HDMI 端口（以下两个系统中的 uname/xrandr/lshw）[Deepin]

我尝试了很多不同的方法，但都不起作用，需要解决这个问题。
答案1
自从你做了一个
- 深度操作系统15.8 LiveUSB
- 后确认其 MD5 校验和显示下载未损坏
- Deepin LiveUSB 没有 HDMI 视频启动，
但是 - 一个Ubuntu 18.04.1 LTS 实时 USB之后制作
- 验证其校验和显示 ISO 下载正常，
- 并且您通过 Ubuntu 成功获得了 HDMI 视频，
这是 Deepin 发行版中的一个缺陷，而 Ubuntu 也是一个源自 Debian 的发行版。因此，我建议您联系深度支持。
注意：制作 Debian LiveUSB 的另一种方法是可用，但更复杂。
