Linux Xorg与Vsync不兼容，使用独显启动，在外置显示器上有时会卡死

解决方法1

切换Wayland
NVIDIA提出的Xwayland的显式GPU同步现在终于合并到XOrg服务器中
mint的bug：Edge检测不到ctrl/alt/shift键了
ue5.4.1开始对wayland的支持了

解决方法2

添加Option "UseNvKmsCompositionPipeline" "false"到/etc/X11/xorg.conf.d/my-vsync-fix.conf.bak
也会导致xorg服务器优先占用独显显存，额外占用150MB显存占用，可以在需要的时候把.bak注释掉，重启cinnamon
Section "Screen"有多个的情况下，优先选第1个来托管xorg桌面服务器

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    Screen      1  "Screen1"
EndSection

Section "Device"
    Identifier     "iGPU"
    Driver         "modesetting"
    VendorName     "AMD Corporation"
    BusID          "PCI:6:0:0"
EndSection

Section "Device"
    Identifier     "dGPU"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "dGPU"
    Option "UseNvKmsCompositionPipeline" "false"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "iGPU"
EndSection
