seems a decent summary of the Intel vs. Modesetting driver situation. The 
Modesetting driver was moved from a standalone package into the server in 
1.17.0, long before 16.04 with server 1.18.3 was released. So far, all my 
Intel gfx installations that work at all with the Modesetting driver work at 
least as well as they ever did with the Intel driver.
