<pre>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.</pre>
