===========================
在NVIDIA显卡环境运行Sway
===========================

最新的Sway版本已经隐含有限支持了NVIDIA显卡，运行参数::

   __GL_GSYNC_ALLOWED=0; __GL_VRR_ALLOWED=0; WLR_DRM_NO_ATOMIC=1; export QT_AUTO_SCREEN_SCALE_FACTOR=1; export QT_QPA_PLATFORM=wayland; export QT_WAYLAND_DISABLE_WINDOWDECORATION=1; export GDK_BACKEND=wayland; export XDG_CURRENT_DESKTOP=sway; export GBM_BACKEND=nvidia-drm; export __GLX_VENDOR_LIBRARY_NAME=nvidia; export MOZ_ENABLE_WAYLAND=1; export WLR_NO_HARDWARE_CURSORS=1; sway --unsupported-gpu

现有版本已经移除了之前的参数 ``--my-next-gpu-wont-be-nvidia`` ，改成了 ``--unsupported-gpu`` ，看起来应该可以基本运行。需要NVIDIA的驱动 ``495+`` 以上，后续我会验证测试
