我在配有 2 个显示器的电脑上安装了 Ubuntu。一个显示器通过电缆连接到处理器视频VGA
,另一个显示器通过DVI
电缆连接到独立 Nvidia 显卡。
计算机是双启动的,Windows
可以看到两个显示器并在其上扩展桌面。
后者正在工作,而前者已无任何踪迹。
是否可以强制此东西找到我拥有的所有显示器/视频卡?
更新
我已经下载了英特尔图形工具并运行了它的更新功能,但
在此之前,我进入系统设置 | 软件和更新 | 附加驱动程序,发现第二台设备从“不工作”变成了这样:
不幸的是,Ubuntu 忘了告诉我这个设备是什么,它可能与显卡不同……
更新2
当我尝试安装该库时,它显示:
$ sudo apt-get install libglapi-mesa

libglapi-mesa is already the newest version (17.0.7-0ubuntu0.16.04.1).
更新 3
我绕过了包不匹配的问题,但仍然没有看到第二张视频卡。
