Ubuntu 20.04.3——启动时黑屏

Ubuntu 20.04.3——启动时黑屏

我在 Ubuntu 启动时遇到一个典型的“黑屏”问题,我无法修复它。

问题:

  • 如果没有“nomodeset”选项GRUB_CMDLINE_LINUX_DEFAULT,我的笔记本电脑的主显示器就会变黑,但 HDMI 显示器可以工作。
  • 使用“nomodeset”选项后GRUB_CMDLINE_LINUX_DEFAULT,HDMI 显示器上出现黑屏,但我的笔记本电脑的主显示器可以工作。

使用“nomodeset”不是一个解决方案,因为它使用的驱动程序不支持很多东西(例如第二个屏幕)

计算机规格:

  • ProBook 450 G7
  • 英特尔酷睿 i5-10210U
  • 英特尔超高清 620
  • Ubuntu 20.04.3(全新安装)

一些命令的结果:

奖励:当计算机进入省电模式时,屏幕会变黑,我必须强制关机。

你知道如何解决这个问题吗?

谢谢

HP 自动更新 BIOS 后我的问题就解决了。
