Status in xorg package in Ubuntu: New Bug description: Hello Guys, I'm currently running an up-to-date Xenial system on amd64 (PC) platform. Whenever I launch the OS with stock kernel (4.4.X) all seems good. Whenever I launch the OS with let's say a mainline-PPA kernel whose version is above 3.6.0 inclusive (3.5.X are functional), or stock yakkety kernel nowadays (4.8.X), kernel fails to setup my graphics card, whose description is appended in a few text files I joined to this message.
