            Bug ID: 99922
           Summary: [NVE4] [regression, bisected] 4.10 (atomic): X shows
                    black screen with cursor after monitors turn off
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Keywords: bisected
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: kevin-Fk+Xth6EFAKtEw7EPzjzzg@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

On Linux 4.10, after waking monitors up from powersave mode, X displays only a
black screen with a movable cursor on all three monitors. Linux 4.9.11 does not
exhibit this issue.

I initially noticed the issue with a triple-monitor setup, but it still occurs
even if only one monitor is plugged in via HDMI.

I've bisected the issue to the following atomic-mode-setting commit (full git
bisect log attached):

commit 839ca903f12ef8f09374e0b655456482536a733e
Author: Ben Skeggs <bskeggs-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

    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.

    Signed-off-by: Ben Skeggs <bskeggs-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

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.

Are you able to try with xf86-video-modesetting instead of the nouveau 2d

Yeah, the nouveau 2D driver doesn't handle page flips failing correctly for
some reason (this can happen under atomic when DPMS is set to a power-saving
mode).

I wasn't able to reproduce this with the nouveau DDX running in its (default)
DRI2 mode, only DRI3, so I hadn't prioritized looking into it.

Lyude has posted a patch[1] which should address this issue.

I can also confirm that the DPMS problem with kernel 4.10.x is gone after
installing xorg-x11-drv-nouveau-1.0.14-1.fc25.x86_64.

1.0.14 includes the patch:

I had the same issue on an Intel-based system.  I managed to overcome it by
changing the BIOS video settings from PEG to IGD.  I have to use the on-board
video to see the BIOS bootup screen, but once Linux takes over, both of my
monitors work fine.

I see this regularly on a system with

Kubuntu 17.10 (that is linux 4.13.x)
Nvidia G84GL [Quadro FX 570]
Xserver xserver-xorg-video-nouveau 1.0.15

so the issue does not seem to be solved yet.

When the power management kicks in and the screen dims, it is then impossible
to get back to work. Ideally, by moving the mouse you should get the screenlock
screen and the possibility to enter a password to disable the lock. In fact,
you only get a black screen with a moving cursor.

That's a contradiction in terms. This bug was for a GK104. You have a G84.

Have you gone through all the diagnostic stages that the OP went through and
you've found the same thing? Seems highly unlikely. Even if it's true, it's
still a different bug.
