我在使用两张 Nvidia GTX 690 卡的 Kubuntu 15.10 x64 上安装时遇到了问题。
我试过:
# Install Nvidia drivers
sudo apt-get purge nvidia*
sudo apt-get update
sudo apt-get install nvidia-340 nvidia-prime # http://askubuntu.com/a/698736/44876
重启
我检查了 Nvidia 驱动程序是否正确安装:
f@f-Aurora-R4:~$ nvidia-smi

由于 Nvidia 驱动程序似乎已正确安装,因此我继续安装 Nvidia CUDA 工具包:
sudo apt-get install nvidia-cuda-toolkit
然后我重新启动并尝试安装 CUDA:
# Install cuda
wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1504/x86_64/cuda-repo-ubuntu1504_7.5-18_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1504_7.5-18_amd64.deb
sudo apt-get update
sudo apt-get install cuda
重启
这导致 Nvidia 驱动程序不再工作(启动时不再有 GUI)。我做错了什么?
Kubuntu 安装是全新的,我只sudo apt-get update;sudo apt-get upgrade
在其上进行过安装。
