Hi all, I must have omitted a few pieces of information in fact : - The description of the bug - Error messages - The text files (logs, ...) I mentioned in my previous post
The files are joined as an attachement to this post, and here follow my bug description and error messages extracts. With Linux 4.5.x or below all is good : - Screen resolution of 1600x900 (native screen resolution) - Accelerated 3D graphics on AMD TURKS hardware - Plymouth shows up and animates well both on OS startup and OS shutdown - No scary message in kernel logs (dmesg) With Linux 4.6.x or above all is bad : - Screen resolution of 1152x864 (lower than native) - Software rendered 3D graphics on llvmpipe - Plymouth neither shows up on OS startup nor on OS shutdown - Scary messages in kernel logs (extracts follow) : [ 5.291603] [drm] Initialized drm 1.1.0 20060810 ...

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. In hope this helps, Sincelely, Vécu P.S. : I very suspect this is a mainstream bug ; for any complimentary info. please don't hesitate to post and ask for more.
