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
