因此，我有这个选项Launch Using Discrete Graphics Card，我推测它允许我打开应用程序，以便它们使用笔记本电脑上的独立 NVIDIA GTX 1650 显卡。这似乎相当于使用switcherooctl launch命令。

当我实际使用它时，它不起作用，因为它不能正常工作。
例如，在启用硬件加速的 Chromium 上，我得到：

但我正常启动的时候并没有遇到这样的问题：

使用switcheroo命令启动，我们可以在终端看到以下输出：

电子应用程序也无法工作，要么黑屏，要么只显示前一个窗口的冻结屏幕。
类似地，启用硬件加速的 Sublime Text 也会出现此错误：
