HDMI 显示器停止工作

它曾经工作过，但突然停止工作。（显示器无显示，显示器电源指示灯一直闪烁）

系统日志：（如果我需要添加更多内容请告诉我）

（每个命令都是在 HDMI 电缆连接到笔记本电脑（Dell Inspiron 14 7000）和显示器（Acer）时运行的

get-edid | parse-edid

This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 2
No EDID on bus 4
No EDID on bus 5
No EDID on bus 6
2 potential busses found: 1 3
Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
256-byte EDID successfully retrieved from i2c bus 1
Looks like i2c was successful. Have a good day.

答案1

这很有趣，也难以解释，但我所做的就是解决这个问题

  • 使用 cvt 创建模式行字符串$ cvt 1920 1080（我知道显示器的分辨率）
  • 编辑xorg.conf并强制 Modeline 并告诉它忽略显示器发送的 EDID 信息。（https://wiki.ubuntu.com/X/Config/HDMI）

这些步骤在我重新启动时破坏了我的系统，它进入了某种安全模式，我可以在其中编辑我的 xorg.conf。这也使外部显示器上的显示恢复正常。在对 xorg.conf 进行一些调整后，我能够正确配置，重新引导到正常模式，并用我备份的原始配置替换修改后的配置，一切正常。
