我的 ubuntu gnome 不使用笔记本电脑中的nvidia GTX ，而是使用英特尔 gpu来渲染大型应用程序和 GUI。制作扩展程序会blur my shell导致一些延迟和帧丢失

我尝试了几乎所有公共解决方案，例如设置 nvidia prime 设置
$ prime-select query
nvidia
笔记本电脑仍然不使用 nvidia gpu 来渲染扩展效果，例如模糊我的外壳并导致延迟
我最终只用一件事就可以做到这一点：编辑或创建文件/etc/udev/rules.d/61-mutter-primary-gpu.rules
然后添加内容：
ENV{DEVNAME}=="/dev/dri/card2", TAG+="mutter-device-preferred-primary"其中card2是我的nvidia 驱动程序。你可以通过以下方式检查
sudo ls -l /sys/class/drm/cardX/device/driver还要确保您有 nvidia 非服务器驱动程序包，否则可能会导致启动失败
