18.04 - NVIDIA GTX 970 出現螢幕撕裂

我似乎在 Ubuntu 18.04 中遇到了螢幕撕裂的問題，並通過運行此測試得到了證實：

我在谷歌搜尋了一段時間，但我發現的只是更改文件/etc/modprobe.d/nvidia-drm-nomodeset.conf和添加的建議

options nvidia-drm modeset=1

但這沒有任何作用。

這些是我正在使用的驅動程式：

我可以做什麼來解決這個問題？

更新：

這是我的 X 配置：

我的筆記型電腦也有同樣的卡，沒有撕裂。但請注意，我使用的是 384 版本，並且不希望使用更高的版本號，這可能會使我的設定變得複雜。在系統設定過程中，我按照慣例查閱了 Arch Linux 的信息聖經建議：

Section "Device"
        Identifier "Nvidia Card"
        Driver     "nvidia"
        VendorName "NVIDIA Corporation"
        BoardName  "GeForce GTX 1050 Ti"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    Option         "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}"
    Option         "AllowIndirectGLXProtocol" "off"
    Option         "TripleBuffer" "on"
EndSection

Full Composition Pipeline 和 Triple Buffer 是最重要的。

今天我的設定是這樣的：

$ cat /etc/X11/xorg.conf

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Monitor"
    Identifier "DP-1-1"
    Modeline "3840x2160_54.00"  637.50  3840 4152 4568 5296  2160 2163 2168 2230 -hsync +vsync
    Option "PreferredMode" "3840x2160_54.00"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:0@0:2:0"
    Option "AccelMethod" "None"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

請注意，此處未設定強制合成管道和三重緩衝區。它曾經在nvidia-settingsGUI 配置上，但我不再在那裡看到它了。
