Lenovo Ideapad s340 无法识别 Mint 19.3 HDMI 端口

Lenovo Ideapad s340 无法识别 Mint 19.3 HDMI 端口

所以我的联想ideapad s340运行linux mint 19.3 cinnamon 64位5.3.0-28-generic。 (笔记本电脑已经用了 3 天,没有操作系统 [只有 BIOS],我在第一次启动时安装了 mint)。

GPU 是 Intel UHD 620(无 Nvidia),驱动程序管理器显示没有 Intel 驱动程序,它只显示空白屏幕并显示“没有使用专有驱动程序”。

我的笔记本电脑甚至无法识别 HDMI 端口的存在(当我运行 xrandr 时,它不会出现在那里),并且显示设置仅显示笔记本电脑的主显示器,尽管有一个功能齐全的显示器正确插入 HDMI 端口(尝试了 3 个显示器,包括1台电视),显示器只显示“无信号”

答案1

尝试在 BIOS 中将启动模式从传统模式更改为 UEFI。启动时按 F2 即可访问 BIOS。

答案2

解决方案:

命令

sudo strings /sys/firmware/acpi/tables/DSDT | grep -i 'windows ' | sort

列出了几个 Windows 选项,最新的是“Windows 2018”,所以我使用以下命令编辑了 grub 菜单

xed admin:///etc/default/grub

去了线:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

并添加了

acpi_osi=! \"acpi_osi=Windows 2018\" ,

将行更改为:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=! \"acpi_osi=Windows 2018\""

之后我运行“sudo update-grub”并重新启动计算机。

然后我进入 BIOS 并将设置“启动模式”从“传统支持”更改为“UEFI”,现在它可以工作了
