Method Advantages Disadvantages
bumblebee, using “render offload” Uses the dGPU only when requested, allows power saving, is the Manjaro default Some overhead so lower raw performance
PRIME, using “output offload” Uses the dGPU directly, better raw performance dGPU and iGPU both powered on constantly, needs manual configuration
optimus-manager Easy switch between iGPU and dGPU usage Very much pre-release and under rapid development
video-hybrid-intel-nvidia-440xx-prime NVIDIA’s updated render offloading. Works perfectly on supported hardware. Only supported by 440xx and newer driver series
  • glxspheres64 图形测试程序
  • nouveau ：nvidia的开源驱动
    • DRI_PRIME=1 glxspheres64 通过此驱动，以nvidia运行程序
  • prime-on: nvidia 闭源驱动提供的脚本，以nvidia运行某个程序

使用optimus-manager

运行optimus-manager —print-mode。或者，您可以运行glxinfo | grep “OpenGL renderer”以获取当前 GPU 的名称。

使用optimus-manager-qt 切换到nvidia不成功

通过optimus-manager-qt 设置了开启启动nvidia了，开机桌面漰溃了O_O，只能crtl+alt+f2进入tty，修改Optimus了-manage的配置，还原开启使用混合模式。

通过journalctl -u optimus-manager.service看到缺少acpi_call的错误，就根据内核安装了对应acpi_call包。不报错了，但是切换不成功。

重新安装了一次能用了

使用prime-on

使用nvidia官方驱动自带的prime-on运行程序，但是效果一般般。可以修该桌面启动项，在/usr/share/applications里，启动命令前加上prime-on

运行效果
