我有一台配备 Nvidia GT 1030 显卡的电脑，我正尝试使用 ubuntu-frame 显示一个简单的网站。最初，提示显示没有任何问题。但是，当我尝试使用 ubuntu-frame 显示更复杂的东西时，我遇到了一个空白屏幕。
我安装了nvidia-core22和ubuntu-frame（channel=22/stable），并使用 连接它们snap connect ubuntu-frame:graphics-core22 nvidia-core22:graphics-core22以利用 Nvidia 驱动程序ubuntu-frame。
日志ubuntu-frame如下：

据我所知，GMB 不能与 Nvidia 卡一起使用，但 EGL 可以。
有人有同样的问题吗？你知道如何解决这个问题吗？
谢谢

我知道nvidia-core22并且ubuntu-frame可以在经典的 Ubuntu（服务器或桌面）上运行，但您需要一个支持 Nvidia 的内核快照才能在 Ubuntu Core 上运行。
此外，您还需要pc-kernel和nvidia-assemblesnap 来组装和加载 nvidia kernelspace 驱动程序。（感谢Xnox 对此进行了澄清！
这很不方便，但反映了 Nvidia Linux 支持打包方式的局限性
