from Pont=
us Gr=C3=A5sk=C3=A6g
I appear to be experiencing the same bug. Same set of internal=
and external
connectors. My hardware is Lenovo G75 A10-7300 [Kaveri]
Kernel booted with=20
- amdgpu.cik_support=3D1=20
- radeon.cik_support=3D0=20
- amdgpu.dc=3D1=20
- drm.debug=3D1
The internal (eDP) display fails to work. The VGA display doesn't work eith=
er
(as expected), and I can't comment on the HDMI as I don't have an HDMI moni=
tor.
Used ssh to get in and copy the dmesg buffer.
I do not have the capability to compile kernel+patches. Sorry.
