Comment 20 for bug 1559308

Ok, it seems as Intel has just 'forgotten' to make their newest drivers available. That's why they are not included in 16.04.

There is a German article on that available here: http://www.heise.de/newsticker/meldung/Linux-Intels-neue-Iris-Grafik-Treiber-Support-in-Sicht-3193993.html (translation: https://goo.gl/Cm18Kv). It mainly describes the (much bigger) issues with the Iris-550 GPU. However, they acknowledge that the missing driver patches might also affect users with HD 510 and HD 535 GPUs (so I guess also the HD 520 one).

Let's hope the Ubuntu developers integrate the already available patch as soon as possible. Maybe there is a temporary work around?
