Just to add my configuration to the mix, I'm using MySQL 5.7.8 which has the same strict sql_mode rules by default.

• I finally figured the following working in my /etc/mysql/my.conf:

  [mysqld]
  sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"
  

i.e. dash, not underscore and quotes around the value.

• I have NO other my.conf files other than /etc/mysql/my.conf

• There are some extra config includes being loaded from /etc/mysql/conf.d/ but they are blank.

And that seems to work for me.
