我有一台双启动 Windows 10 和 Ubuntu 22.10 的 PC。我有一台外接电视作为显示器，通过 VGA 电缆连接，我知道电视和 VGA 都完美支持 1920x1080，因为它可以在 Windows 10 上运行。但是，当我尝试在 Ubuntu 的设置中将显示器设置为 1920x1080 时 - > 显示，屏幕只是闪烁并恢复到旧分辨率。

我有来自 hardinfo 的以下系统信息：

    Operating System: Ubuntu 22.10
    CPU: Intel(R) Care(TM) i3-4130t CPU @ 2.90Ghz 1 physical process, 2 cores; 4 threads
    RAM: 3920360 KiB
    Motherboard: Hewlett-Packard 21D0
    Graphics: 1680x1050 Mesa intel(R) HD Graphics 4400 (HSW GT2) The X.Org Foundation
    Storage: ATASTS001_7012-PWS14
    Audio: HISA-Intel-FICA Intel PCH

我的 xorg.conf 文件的内容是：

Section "Monitor"
    Identifier "Monitor0"
    Modeline "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
    Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
    Option "PreferredMode" "1680x1050_60.00"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
        Modes "1680x1050_60.00"
    EndSubSection
EndSection

当我运行 $ xrandr 时，我得到以下输出：

Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 16384 x 16384
VGA-1 connected primary 1680x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)

我怎样才能在 Ubuntu 22.10 上获得 1920x1080？”
