Ubuntu 20.04 上的 AOC G2460PG 分辨率停留在 640x480，而英特尔集成显卡 UHD 630 无法达到 1920x1080

我使用的是英特尔集成显卡 UHD 630。我有一台 AOC G2460PG 显示器，它的驱动程序似乎有问题，分辨率卡在 640x480。我找到了一个解决方案这样做是可行的，但我不确定第二部分，因为我没有目录/usr/share/X11/xorg.conf。在查看了Ubuntu维基我看到它位于/etc/X11，但我不知道应该在其中输入什么设置，或者我是否应该/etc/X11/xorg.conf.d/10-headless.conf为 Ubuntu 创建相同的文件/路径。任何帮助都将不胜感激。到目前为止，我每次重启后都只能从 cli 执行第一步，因为设置不会保存，但至少我可以通过这种方式获得 1920x1080 分辨率。

这些是我重启后使用的命令：

$ xrandr --newmode "1920x1080_85.00" 198.500 1920 1968 2000 2080 1080 1083 1088 1124 +Hsync -Vsync
$ xrandr --addmode DP-1 "1920x1080_85.00"
$ xrandr --output DP-1 --mode "1920x1080_85.00"

我尝试将以下内容添加到/usr/share/X11/xorg.conf.d/20-monitor.conf：

Section "Monitor"
    Identifier "DP-1"
    Modeline "1920x1080_85.00" 198.500 1920 1968 2000 2080 1080 1083 1088 1124 +hsync -vsync
    Option "PreferredMode" "1920x1080_85.00"
EndSection

Section "Screen"
    Identifier "Screen0"
    Monitor "DP-1"
    DefaultDepth 24
    SubSection "Display"
        Modes "1920x1080_85.00"
    EndSubSection
EndSection

Section "Device"
    Identifier "Device0"
    Driver "intel"
EndSection

这不起作用。这是我的输出xrandr --query --verbose：

经过几次尝试/编辑后，以下配置对我有用

Section "Monitor"
    Identifier "Displayport-1"
    Modeline "1920x1080_85.00" 198.500 1920 1968 2000 2080 1080 1083 1088 1124 >
    Option "PreferredMode" "1920x1080_85.00"
EndSection

Section "Screen"
    Identifier "Screen0"
    Monitor "Displayport-1"
    DefaultDepth 24
    SubSection "Display"
        Modes "1920x1080_85.00"
    EndSubSection
EndSection

Section "Device"
    Identifier "Device0"
    Driver "amdgpu"
EndSection

由于某些未知原因，我不得不保留英特尔集成显卡Driver "amdgpu"。我之前尝试过Driver "intel"，但遗憾的是没有成功。
