Ubuntu 16.04 — VSync 未启用，屏幕撕裂

我在用着：

  • GTX950M
  • 集成英特尔芯片组显卡 i7-6700
  • Ubuntu 16.04

glxgear检测到大约 16000 fps。

这些是我的 nvidia 驱动程序：

aptitude search nvidia | grep ^i 
i   nvidia-361                      - NVIDIA binary driver - version 361.42     
i A nvidia-opencl-icd-361           - NVIDIA OpenCL ICD                         
i A nvidia-prime                    - Tools to enable NVIDIA's Prime            
i A nvidia-settings                 - Tool for configuring the NVIDIA graphics d

这是我的 nvidia 配置：

以及 Xorg 配置：

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

    Identifier "intel"
    Device "intel"

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

但是我看到很多来自 chrome、视频等的撕裂...

任何想法？

我不记得我从哪里获得这些设置的链接。我也有 Intel i7-6700，但有稍微新一点的 GTX970M。经过多次反复尝试，这些设置对我有用（旧设置被注释掉了）：

$ cat /etc/X11/xorg.conf.d/20-nvidia.conf
Section "Device"
    Identifier "nvidia"
    Driver     "nvidia"
#    BusID      "PCI:1@0:0:0"
#    Option     "ConstrainCursor" "off"
    VendorName "NVIDIA Corporation"
    BoardName  "GeForce GTX 970M:"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
#    Option "AllowEmptyInitialConfiguration" "on"
#    Option "IgnoreDisplayDevices" "CRT"
#          Dec 14 2017 - Copy from /etc/X11/xorg.conf to /etc/X11/xorg.conf.d/20-nvidia.conf
#                        Add options from: https://wiki.archlinux.org/index.php/NVIDIA/Troubleshooting
    Option         "metamodes" "nvidia-auto-select +0+0 {ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"
    Option         "AllowIndirectGLXProtocol" "off"
    Option         "TripleBuffer" "on"
EndSection
