为什么我的 GTX 970 无法在 OpenSuse Leap 42.3 上驱动 1080p 显示器？

我正在尝试使用 OpenSuse Leap 42.3 设置工作站，我有 3 个 Asus 1080p 显示器，但不知何故，我的 GPU 在 X Server 启动时未收到 EDID。我已经尝试让它们在 1920x1080 下工作了几个小时，但没有任何效果。每当我切换到 Windows 时，所有显示器都会被完全识别并以 1920x1080 的分辨率顺利显示，无需任何配置。

在 OpenSuse 上，我可以使用xrandr --newmode、xrandr --addmode和 ，以及或xrandr --output DISPLAY-NAME --mode 1920x1080_60.00提供的模式行，强制 3 个显示器中的 2 个为 1080p 。但是，当我这样做时，显示器似乎存在某种同步问题，并且出现闪烁像素的滚动线，小文本变得几乎难以辨认。cvtgtf

我也一直在研究/etc/X11/xorg.conf并尝试了几十次这个文件的迭代，试图在网上建立各种其他论坛帖子和Nvidia Linux 驱动程序文档。

经过几个小时对xorg.conf文件的调整，我让 3 台显示器中的 2 台以 1920x1080 分辨率显示，而第 3 台在登录屏幕上完全不显示，然后在我登录后以 1400x1050 分辨率显示。但是，2 台 1080p 显示器表现出与我手动强制显示设置时相同的闪烁和文本模糊xrandr，因此它们在该分辨率下无法使用。所有 3 台显示器在 1400x1050 分辨率下均可流畅运行，但这不是正确的宽高比，也不是这些显示器的 1:1 分辨率。

我上线了：

内核4.4.76
X 服务器1.18.3
Nvidia 驱动程序390.48 KDE Plasma 5

我查看了HorizSync 31.5-80显示器VertRefresh 56.0-75.0手册上列出的时序（链接和图像位于本问题底部）。无论出于何种原因，输入这些时序均无法启用 1920x1080 作为分辨率，最高只有 1400x1050。

值得注意的是，DFP-0和DFP-4（在配置文件中分别称为DVI1和DVI2）都位于 DVI 端口上，而DFP-1（标记为HDMI）位于 HDMI 端口上。HDMI 显示器是我根本无法达到 1920x1080 的显示器，也是我在未登录 KDE 会话时关闭的显示器。

我也尝试过涉及 Xinerama 的配置，但也没有成功。

我的最新情况xorg.conf是：

我的最新动态Xorg.0.log可见于：

https://paste.fedoraproject.org/paste/~fWRIP5brKHiOlsZ5hvkbw

这是我的显示器手册的下载页面 和这是监视器时序列表的屏幕截图

更新 2018-04-18

我现在也尝试在全新安装的 Debian 4.9 上执行此操作，并且安装了 KDE，我遇到了同样的问题，但至少无需进行手动配置即可让所有 3 个显示器以 1366x768 的分辨率运行，这是正确的宽高比。我尝试使用两个不同版本的官方 NVidia 驱动程序，两次结果完全相同。

为了保持理智，我恢复了全新安装的 Windows 10 映像，但对显示器一无所知，所有 3 个显示器都被视为“通用非即插即用显示器”，所以我猜它们实际上并没有提供 EDID。也就是说，Windows 能够立即以 1920x1080@60hz 运行其中一个，没有任何问题，并且在安装 NVidia 驱动程序后，能够以该配置运行所有 3 个，没有任何问题。

所以我现在的问题是：这是 Linux NVidia 驱动程序的问题吗？如果不是，Windows 是否可能知道一些有关“通用非 pnp 监视器”的信息，我可能能够提取这些信息并用它来配置 X 服务器的监视器？

我认为 1920x1080 60hz 显示器的配置没有什么特别之处，cvt模式行应该可以正常工作，对吗？

更新/解决方案 2018-04-19

对我来说，这个技巧最终是不是使用 cvt/gtf 的模式行，但指定精确的Horizsync和而VertRefresh不是范围。我的最终工作 xorg.conf 如下。注意：我不知道添加{ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}有什么作用，据说它可以减少屏幕撕裂，但我看不出有什么区别。无论哪种方式，该行对于解决我的问题都不是必需的，只需手动指定HorizSync和VertRefresh并仅列出一个监视器而不是三个监视器即可。如果我的所有 3 个监视器都不相同，则可能需要多个监视器。

这是我的配置，可以帮助您排除故障。我连续将 2、3 甚至 4 个 1440p 或 1080p 的屏幕插入我的配置中，从未出现任何问题。多年来。

您是否尝试过使用终端中的 nvidia-settings 来启动其 GUI？它显然会为您设置 xorg。您是否尝试过任何 ubuntu 衍生的东西？或者 ubuntu 本身？
