Commen= t # 9 on bug 10707= 2 from Pont= us Gr=C3=A5sk=C3=A6g 
Looking at your dmesg output, it looks like you might have hit=
 this bug/issue:
bug 105880

"[dc] No support for LVDS or VGA connectors (Cannot find any crtc or s=
izes)"

AMD/Harry Wentland/Alex Deucher have commits in the mainline kernel to disa=
ble
the DC code by default for Bonaire, Kabini, Kaveri, and Mullins as certain
hardware interfaces are not supported in the DC code. Your cpu (from dmesg)=
 is
an AMD A8-7650K Radeon R7, codename Kaveri.

The clue in dmesg output is the following errors:

[   14.186318] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector
ObjectID from Adapter Service for connector index:1! type 0 expected 3
[   14.186458] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector
ObjectID from Adapter Service for connector index:3! type 0 expected 3
[   14.186592] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector
ObjectID from Adapter Service for connector index:4! type 0 expected 3
[   14.186725] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector
ObjectID from Adapter Service for connector index:5! type 0 expected 3

You might try forcing amdgpu.dc=3D0 in the kernel command line to ensure yo=
u use
the old driver code.
