Unfortunately, this simple fix does not work for UXA as DPMS is used by the xserver to turn off CRTCs and outputs. Since UXA does not implement CRTC DPMS, this commit causes us to fail to turn off outputs. The kernel has been fixed up in the meantime and that commit has been recommended to be backported to all stable kernels: commit c9976dcf55c8aaa7037427b239f15e5acfc01a3a Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Sun Sep 29 19:15:07 2013 +0100 drm/i915: Only apply DPMS to the encoder if enabled so it should be safe for UXA to rely on its old behaviour.
