手順

必要パッケージのインストール

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-367
$ sudo apt-get install mesa-common-dev
$ sudo apt-get install freeglut3-dev

ダウンロード

https://developer.nvidia.com/cuda-toolkit からダウンロード（要ログイン）

cuda_8.0.27_linux.run を選択（1.4GB）

パス追加

~/.bashrc に以下を追加

export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_HOME=/usr/local/cuda

gcc 4.8 系に戻す

$ cd /usr/bin/
$ sudo unlink gcc
$ sudo ln -s gcc4.8 gcc
$ sudo unlink g++
$ sudo ln -s g++-4.8 g++

X無しのモードで作業

CTRL+ALT+F1を押して黒画面へ。

ログイン後、
sudo init 3 を実行して、非X環境してから、先ほどダウンロードしたインストーラを実行。

$ chmod +x cuda_8.0.27_linux-run
$ sudo sh ./cuda_8.0.27_linux-run

EULAが長いけど、f 連打。
最後に

===========
= Summary =
===========

Driver:   Installed
Toolkit:  Installed in /usr/local/cuda-8.0
Samples:  Installed in /home/lekto, but missing recommended libraries

Please make sure that
 -   PATH includes /usr/local/cuda-8.0/bin
 -   LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin
To uninstall the NVIDIA Driver, run nvidia-uninstall

Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/doc/pdf for detailed information on setting up CUDA.

Logfile is /tmp/cuda_install_21782.log

とか出ればOK。

$ sudo reboot

再起動後、Xログインは出来ない

CTRL+ALT+F1を押して再び黒画面へ。
ログイン。

gcc 5 系に戻す

$ cd /usr/bin/
$ sudo unlink gcc
$ sudo ln -s gcc-5 gcc
$ sudo unlink g++
$ sudo ln -s g++-5 g++

ドライバーを再インストール

$ sudo apt-get install nvidia-367 --reinstall

リブート後はX環境でログインできるはず

$ sudo reboot

補足

16.04 のとってきたISOの問題か、デフォルトでロケールが日本語になってた。

$ localectl
   System Locale: LANG=ja_JP.UTF-8
       VC Keymap: n/a
      X11 Layout: jp

コンソールまで日本語だとつらい？し、ググりづらいので英語に。

$ sudo update-locale LANG=en_US.UTF-8
$ localectl
   System Locale: LANG=en_US.UTF-8
       VC Keymap: n/a
      X11 Layout: jp
