Ubuntu 18 + Nvidia 顯卡螢幕撕裂(screen tearing)問題

什麼叫screen tearing：

解決方法：

1. 安裝nvidia-settings
   sudo apt-get install nvidia-settings
   
   
2. 打開NVIDIA X Server Settings後，選擇左邊X Server Display Configuration/Advanced...，把Force Composition Pipeline或Force Full Composition Pipeline個別其中一個打勾試試
   
   
3. 記得按Save to X Configuration File儲存設定到 /etc/X11/xorg.conf
   
   
4. 選擇左邊nvidia-settings Configuration，按右邊Save Current Configuration儲存設定到 ~/.nvidia-settings-rc

如果是像在瀏覽器chrome上看影片的話，瀏覽器的硬體加速選項可能也要調整：
