drd.ko缺少CUDA 6.5/Ubuntu 14.04/AWS EC2 GPU实例g2.2xlarge

Question

要在AWS EC2 g2.2xlarge实例上的Ubuntu 14.04.1 LTS上安装CUDA 6.5,无论是通过.deb文件还是.run文件安装

.sudo ./cuda_6.5.14_linux_64.run --kernel-source-path=/usr/src/linux-headers-3.13.0-34-generic

我总是得到关于丢失drm.ko的相同错误.代码编译似乎很成功.下面是日志.(我在安装前重新启动)

内核模块编译完成.

无法确定是否启用了安全启动:没有此类文件或目录

内核模块加载错误:没有这样的文件或目录

驱动程序安装无法找到内核源.请确保已正确安装和设置内核源包.

Answer 1

该错误是由NVIDIA驱动程序所需的drm模块丢失引起的.默认情况下,Ubuntu AMI安装最小的通用Linux内核(linux-image-virtual),不包括drm模块.要修复它,请安装完整的通用内核linux-image-generic.安装linux-image-extra-virtual会起作用,因为它只是linux-image-generic的过渡包.我建议安装linux-generic来包含头文件和图像.总结一下:

sudo apt-get install linux-generic
