On Linux 4.10, after waking monitors up from powersave mode, X=

I initially noticed the issue with a triple-monitor setup, but it still occ=

even if only one monitor is plugged in via HDMI.

I've bisected the issue to the following atomic-mode-setting commit (full g=

    drm/nouveau/kms/nv50: transition to atomic interfaces internally

    This commit implements the atomic commit interfaces, and implements the
    legacy modeset and page flipping interfaces on top of them.

    There's two major changes in behavior from before:

    - We're now making use of interlocks between core and satellite EVO
      channels, which greatly improves our ability to keep their states
      synchronised.
    - DPMS is now implemented as a full modeset to either tear down the
      entire pipe (or bring it back up).  This choice was made mostly
      to ease the initial implementation, but I'm also not sure what we
      gain by bring backing the old behaviour.  We shall see.

    This does NOT currently expose the atomic ioctl by default, due to
    limited testing having been performed.

Dmesgs and Xorg logs will be provided for the following configurations that
exhibit the issue:
 - 4.10, with one monitor attached
 - 4.10, with three monitors attached
 - A bisected revision that displays the issue (seems to have a bit more
information)

I'm using an MSI GTX 770 2GB; vbios will be attached.
