我真的很抱歉再次提起这个话题但是“我还没有找到我要找的东西……”。
我尝试过多种具有多种行为的解决方案，但都无法使其正常工作。
首先，我还应该在 Vivid 上使用 Bumblebee 吗？或者有像 Primus 这样的可行替代方案？我试过 Primus，但我的 kubuntu 突然停止工作了。我对 Linux 操作系统的体验一般，但我真的会爱上它。——只有这件事让我如此沮丧。
我担心我必须重新安装 kubuntu，因为我的 nvidia 驱动程序安装步骤出错了 - 但我已经准备好这样做了。
请让我知道我能做什么以及我应该做什么。

答案1
我有联想 Y580，在 Kubuntu 15.04 上遇到了类似的问题。Bumblebee 在 Kubuntu 14.04 LTS 上运行良好。我别无选择，只能恢复到 14.04。您可以尝试删除 bumblebee 并仅安装 nvidia prime 吗？让混合显卡运行 nvidia-prime GT650M 我想知道结果。谢谢
