Description
With KMS:No link with displayport and A6-3600 APU from 4.4.x to 4.11.0.rc8, unless nomodeset kernel boot parameter
Please see my original distribution bugreport at
https://bugzilla.opensuse.org/show_bug.cgi?id=1035240
Tested with OpenSuSE Leap 42.2 (all x64) kernels 4.4.x up to 4.11.0.rc8 kernels
Hardware:
Motherboard: F1A75-V PRO by Asus, with AMD cpu/gpu/apu all-in-one: AMD A6-3600 APU with Radeon(tm) HD Graphics
hdmi port on motherboard and on the same monitor with hdmi cable works and produces link, same motherboard with displayport cable and ports and same monitor at its displayport port gives no link, unless one uses the "nomodeset" kernel boot parameter.
Thank you.
