Subject: [PATCH xf86-video-amdgpu 1/3] xf86-video-modesetting: Record non-desktop kernel property at PreInit time
Date: Fri,  2 Mar 2018 20:49:29 -0800	[thread overview]
Message-ID: <20180303044931.6902-2-keithp@keithp.com> (raw)
In-Reply-To: <20180303044931.6902-1-keithp-aN4HjG94KOLQT0dZR+AlfA@public.gmane.org>

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]
