我有一块带有集成显卡的 Z97X-Gaming 3 主板,此外还有 NVIDIA RTX 2080Ti。
一个显示器连接到 NVIDIA HDMI 输出,另一个显示器连接到主板 DVI 输出,该输出为空白;最初,在登录屏幕之前,我可以看到输出文本 Ubuntu,但随后登录屏幕出现在另一个连接到 NVIDIA 显卡的显示器上,初始显示器变为空白。
我尝试修改 BIOS 设置,但所有尝试均未成功。
这些是显卡:

如果有人能提供有关如何启用双输出的建议,我将不胜感激。

我通过编辑 xorg.conf 解决了这个问题。
我在其中添加了设备、屏幕和显示器的附加部分。修改后的与显示设置相关的部分现在如下所示:
