未检测到外接显示器，刷新率停留在单一分辨率

我的笔记本电脑上刚刚安装了 Lunar Legion 5i Pro Gen 7 (16" Intel) (12700h + 3070ti)。插入的外接显示器甚至没有显示在设置中。分辨率选择卡在 2560 * 1600，刷新率也锁定在 93Hz（最高为 165hz）

使用：nvidia-driver-535，x11和内核版本6.2.0-24-generic。

xrandr：

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 2560 x 1600, current 2560 x 1600, maximum 2560 x 1600
default connected primary 2560x1600+0+0 0mm x 0mm
   2560x1600     93.00*

我尝试使用 和 进行编辑/etc/default/grub以GRUB_GFXMODE=2560x1600修复update-grub，xrandr: Failed to get size of gamma for output default但没有效果。还尝试启动到 grub 菜单，然后按 C 进入命令行并运行vbeinfo，videoinfo但收到​​一条错误消息，提示无法使用安全启动运行该命令。

有没有办法在设置中获取支持的分辨率/刷新率，以及如何让我的外接显示器被识别和显示？

提前致谢

我必须使用由 nvidia-xconfig 生成的配置文件，因为我不知道您的配置，所以我将分享我的配置：（由 生成nvidia-xconfig）

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 470.86

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Mouse0"
    ...your own stuff here


EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Keyboard0"

    ModelName      "Unknown"
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option "NoLogo" "1"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Section "Extensions"
    Option         "COMPOSITE" "Enable"
EndSection

 
Section "InputClass"
    Identifier          "Keyboard Defaults"
    MatchIsKeyboard        "yes"
    Option              "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

目前该文件位于 /etc/X11/xorg.conf.d/90-mhwd.conf。如果生成的文件位于其他位置，您可以将其链接到ln -s

请注意，由于非常特殊的配置（旧硬件），我删除了部分输入部分

由于启动速度慢，我通过随机调整系统来解决这个问题

systemd-analyze blame给了我 20 秒的时间plymouth-quit-wait.service

#old line
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset noplymouth"
#new line
GRUB_CMDLINE_LINUX_DEFAULT="fsck.mode=skip quiet"

令人惊讶的是，经过更快的启动后，我的系统具有了屏幕支持的所有分辨率和刷新率。
