[PATCH xf86-video-amdgpu 1/3] xf86-video-modesetting: Record non-desktop kernel property at PreInit time

Sat Mar 3 04:49:29 UTC 2018


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]
