Subject: [PATCH xf86-video-amdgpu 1/3] modesetting: Record non-desktop kernel property at PreInit time
Date: Mon,  9 Jul 2018 09:26:50 +0200	[thread overview]
Message-ID: <20180709072652.9727-1-michel@daenzer.net> (raw)

From: Keith Packard <keithp@keithp.com>

Save any value of the kernel non-desktop property in the xf86Output
structure to avoid non-desktop outputs in the default configuration.

[Also bump randrproto requirement to a version that defines
RR_PROPERTY_NON_DESKTOP - ajax]
