Bug ID: 107946 Summary: AMDGPU regression, multi-head not working on 4.18, 4.19RC3, but does on 4.16 Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: dave@locochino.com
Created attachment 141576 --> https://bugs.freedesktop.org/attachment.cgi?id=141576&action=edit dmesg output on a broken system, using kernel 4.19_RC3
Multi-head on AMD Vega is not working on kernel 4.18 or 4.19RC, but works fine on 4.16
I'm stuck at kernel 4.16 with my hardware, current stable kernels leave me with just one display working.
Attaching dmesg output from 4.16, 4.18, and 4.19_RC3
