当我正常启动 Ubuntu 20.04 时,出现(背光)黑屏。
当我在启动过程中按住时Shift,我可以看到 grub 启动菜单:
我可以选择“高级选项”,然后选择恢复模式,它以低分辨率启动,并且无需互联网。
我已经清除了所有 nvidia 驱动程序,希望这能解决问题。但并没有。我该怎么办?
我尝试过的方法
模式设置
当我在启动选项中将“quiet splash”替换为“nomodeset”时,我看到的是以下内容而不是黑屏:
我也可以用Ctrl++切换,看到有些变化,但我读不到任何内容。AltF1-F7
恢复模式下的互联网
和本指南我可以在恢复模式下上网。我可以安装另一个 nvidia 驱动程序,但这没用 :-(
显卡有缺陷?
难道是 nvidia 显卡坏了,而英特尔“板载”图形芯片还能用?
在恢复模式下,我得到:
$ nvidia-settings
