根据软件和更新，我的两个 GPU 似乎都启用了其驱动程序：
lspci我也看到了它们：
$ lspci | grep K80
04:00.0 3D controller: NVIDIA Corporation GK210GL [Tesla K80] (rev ff)
05:00.0 3D controller: NVIDIA Corporation GK210GL [Tesla K80] (rev ff)
但是 K80 驱动程序没有显示lshw：
$ lshw -C video
WARNING: you should run this program as super-user.

780 玩游戏很好，但我不能使用 K80。任何帮助我都感激不尽。
