Ubuntu20.04分辨率上的AOC G2460PG在Intel集成图形UHD 630上停留在640x480不能得到1920x1080

Question

我使用英特尔集成图形UHD 630。我有一个AOC G2460PG显示器，似乎与驱动程序有问题，我的分辨率是640x480。我找到了一个可以工作的解决方案，但我不确定第二部分，因为我没有/usr/share/X11/xorg.conf目录。在查看了UbuntuWiki之后，我发现它位于/etc/X11中，但我不知道应该在其中设置什么设置，或者是否应该为Ubuntu创建相同的文件/路径/etc/X11/xorg.conf.d/10-headless.conf。这里的任何帮助都将不胜感激。到目前为止，由于设置不保存，所以在每次重新启动之后，我都要从cli执行第一步，但至少这样我可以获得1920x1080分辨率。

以下是我在重新启动后使用的命令：

$ 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"

我尝试在/usr/share/X11/xorg.conf.d/20-monitor.conf中添加以下内容：

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

那不起作用。下面是我对xrandr --query --verbose的输出：

Answer 1

经过几次尝试/编辑后，下面的配置对我起了作用

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

有了英特尔的集成图形，我不得不保留Driver "amdgpu"，原因不明。在我之前的尝试中，我使用了Driver "intel"，但遗憾的是，这并没有奏效。
