安装RTX2080显卡驱动
近日新购了一台DELL服务器，用于TensorFlow，由于显卡是另加的，需要安装显卡驱动。
服务器配置
- 服务器型号：DELL PowerEdge R730
- CPU：2*Intel(R) Xeon(R) E5-2650 v4
- 内存：8*32G
- 磁盘：2*1.2T，raid 0
- 显卡：2*Nvidia RTX2080
- 系统：Ubuntu 18.04
使用标准Ubuntu 仓库进行自动化安装
首先，检测显卡型号和推荐的驱动程序的模型。在命令行中输入如下命令：
root@rohn-PowerEdge-R730:/home/rohn# ubuntu-drivers devices
== /sys/devices/pci0000:80/0000:80:02.0/0000:82:00.0 ==
modalias : pci:v000010DEd00001E82sv00001043sd00008674bc03sc00i00
vendor : NVIDIA Corporation
driver : nvidia-driver-410 - third-party free
driver : nvidia-driver-415 - third-party free
driver : nvidia-driver-430 - third-party free recommended
driver : nvidia-driver-418 - third-party free
driver : xserver-xorg-video-nouveau - distro free builtin
从输出结果可以看到，目前系统已连接Nvidia RTX2080显卡，CUDA 10.0 需要 410.x 或更高版本。并且建议安装驱动程序是nvidia-430版本的驱动。
安装驱动：
sudo ubuntu-drivers autoinstall
由于DELL对未认证的PCI设备的热量估算不准确造成的，默认会加大风扇风速。可以用ipmi有关命令关闭PCIE卡的响应。
sudo apt install ipmitool
ipmitool raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00
安装完成后重启系统：
reboot
