英特尔视频问题

我是 Ubuntu 新手，有 14.04，我尝试设置超过 800x600 的显示分辨率，但可能犯了一个错误。我预期三星 S27E390H 的分辨率为 1366x768 或 1920 x 1080，但现在分辨率为 1024x768，并且安装了错误的软件包。

答案1

xrandr如果无法通过 xorg 进行设置，则可以使用以下命令来设置所需的分辨率：

cvt 1920 1080 60
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync   #those numbers may vary depending on your screen
xrandr --addmode VGA-1 1920x1080_60.00
xrandr --output VGA-1 --mode 1920x1080_60.00

为了使更改持久，您可以将模型行添加到 xorg 文件，或者创建在系统启动时运行的 bash 脚本。

#!/bin/bash
cvt 1920 1080 60
xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-0 1920x1080_60.00
xrandr --output VGA-0 --mode 1920x1080_60.00

希望这可以帮助

对于未满足的依赖项，您可以尝试先卸载驱动程序，然后安装依赖项，然后再安装驱动程序。

我在 Acer Aspire 5630 笔记本电脑上试用 Ubuntu 16.04LTS 时也遇到了类似的问题，这台笔记本电脑配备了英特尔移动集成显卡 940GM/GMS 943/940GML。我只能达到 1024x768 的分辨率，而 xrandr 无法检测伽玛或任何更高的分辨率。在尝试了网上的许多建议后，我只需安装 xserver-xorg-video-intel 软件包，然后就可以使用原生 1280x800 分辨率。它还解决了启动问题，因为以前我只能使用恢复模式启动并恢复启动，有时必须恢复启动两次。
