![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](https://linux22.com/image/1206985/Ubuntu%2020.04%20%E4%B8%8A%E7%9A%84%20AOC%20G2460PG%20%E5%88%86%E8%BE%A8%E7%8E%87%E5%81%9C%E7%95%99%E5%9C%A8%20640x480%EF%BC%8C%E8%80%8C%E8%8B%B1%E7%89%B9%E5%B0%94%E9%9B%86%E6%88%90%E6%98%BE%E5%8D%A1%20UHD%20630%20%E6%97%A0%E6%B3%95%E8%BE%BE%E5%88%B0%201920x1080.png)
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

SubSection "Display"

这不起作用。这是我的输出xrandr --query --verbose

答案1
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。
