となったら。
まず、chromedriver 単体で起動してみる
$ chromedriver
chromedriver: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory
→ 起動失敗
libgconf2 をインストール
$ apt search libgconf
...
$ sudo apt install libgconf2-4
chromedriver を再実行してみる
$ chromedriver
Starting ChromeDriver 2.29.461571 (8a88bbe0775e2a23afda0ceaf2ef7ee74e822cc5) on port 9515
Only local connections are allowed.
起動した!
再度Python から実行
$ xvfb-run ipython
In [1]: from selenium.webdriver import Chrome
In [2]: d = Chrome()
In [3]:
起動した!
