我有 Ubuntu 10.10 x86_64,带有 Nvidia 9800 gt 和 Nvidia 驱动程序版本 270.41.06
我的显卡有两个 DVI 插槽,但我只使用单显示器配置。现在,我认为主 DVI 插槽可能坏了,所以我想尝试将另一个插槽启用为主插槽,但是,我不知道如何实现。我尝试将显示器插入该插槽,但它不会自动检测到它(这本来很容易就能实现)。
这是我的xorg.conf

答案1
你现在有办法控制电脑吗?你能SSH
进去吗?最后的办法:拔出磁盘,将其插入另一台计算机,这样你就可以编辑文件了。
假设您可以访问某些内容,请/etc/X11/xorg.conf
以 root 身份进行编辑(例如,sudoedit /etc/X11/xorg.conf
如果您已ssh
进入或在您的计算机上)。
您需要查看屏幕部分。Option "metamodes"
其中应该有一行可能看起来像这样:
Option "metamodes" "DFP-0: 1920x1200"
更改DFP-0
为DFP-1
(或者,如果您的卡也有 HDMI 插槽,则为DFP-2
或DFP-3
)。保存文件并启动(或者,sudo restart gdm
如果您通过 SSH 在机器上,则只需运行)
