如何配置 Displaylink USB 显示器？

我看过很多文章，但没有一个全面的指南可以解决这个非常常见的问题，特别是在没有 xorg.conf 文件的 Ubuntu 11.10 中。有没有简单的操作指南（对于像我这样的 Linux 新手）来完成此操作。我看过的其他文章需要相当多的 Linux 能力才能使它们工作。更好的是让 Ubuntu 自动检测这些类型的显示器。

我的屏幕是绿屏，而且驱动程序也已安装。但我就是无法在 Doublesight USB 显示器上看到图像。如有任何帮助，我将不胜感激。

这也许能帮助你实现这一目标。

Displaylink Doublesight DS-90U 显示器正在工作

1）安装构建 displaylink X 服务器所需的依赖项......

apt-get install xinit xserver-xorg xserver-xorg-dev xfonts-base libusb-dev xorg-dev git-core build-essential

2) 从以下网址下载并修复 xserver-xorg-video-displaylink 的源代码发射台并提取源代码。

tar xvfz xserver-xorg-video-displaylink_0.3.orig.tar.gz
cd xf86-video-displaylink

编辑src/displaylink.c

#graphical
gedit src/displaylink.c

#command line
nano src/displaylink.c

注释掉（在前面添加#）以下行...

//#include "xf86Resources.h"
//#include "xf86RAC.h"
//      pScrn->racMemFlags = RAC_FB | RAC_COLORMAP | RAC_CURSOR | RAC_VIEWPORT;
//      pScrn->racIoFlags = RAC_FB | RAC_COLORMAP | RAC_CURSOR | RAC_VIEWPORT;
//      xf86CrtcScreenInit (pScreen);`

3）构建并安装

./configure && make && make install
sudo cp  /usr/local/lib/xorg/modules/drivers/displaylink_drv.so /usr/lib/xorg/modules/drivers/

4）创建/etc/X11/xorg.conf

Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen         0  "DisplayLinkScreen" 0 0
EndSection
Section "Device"
    Identifier  "DisplayLinkDevice"
    Driver      "displaylink"
    Option      "fbdev" "/dev/fb0"
EndSection
Section "Monitor"
    Identifier  "DisplayLinkMonitor"
    # DS-90U is 1024x600 9-inch monitor - remove or change the DisplaySize for other devices
    DisplaySize  190 115
EndSection
Section "Screen"
    Identifier  "DisplayLinkScreen"
    Device      "DisplayLinkDevice"
    Monitor     "DisplayLinkMonitor"
EndSection

5）将 Displaylink 显示器插入 USB 端口（屏幕应变为绿色）

6）重启或重新启动X
