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 sizes)"
AMD/Harry Wentland/Alex Deucher have commits in the mainline kernel to disable
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=0 in the kernel command line to ensure you use
the old driver code.
