                    on display
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)

using latest mainline kernel I get static effect on display and no more (no
login manager)

Mine distro is ubuntu 17.10 but I'm facing the same issue also with mainline
kernel 4.15-rc6

from dmesg I can see, regarding drm:

This bug existed since older versions, I tried also mainline 4.8 

Here you can see mine vga: 
lspci | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Sumo
[Radeon HD 6410D]

that actually is "AMD - A4-3300 Llano" an APU.  

I'm at your disposal in case you need further information.
