Nouveau - Oct 2010 - [Bug 31139] New: Wake from sleep doesn't turn on display(s)

https://bugs.freedesktop.org/show_bug.cgi?id=31139

           Summary: Wake from sleep doesn't turn on display(s)
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: psadauskas at gmail.com
         QAContact: xorg-team at lists.x.org


MacBook Pro (Mid 2010 model) with Nvidia NV50 using nouveau driver on Arch
Linux.

Using both the packaged xf86-video-nouveau (0.0.16_git20100819) and nouveau
from git, the display fails to resume after sleep. Happens when closing the
lid, and using `pm-suspend`, even after removing pm scripts 98video-quirks and
99-video as suggested in other bug trackers. 

After sleeping, the display never comes on, nor does the display backlight.
External displays connected to the Mini-DisplayPort->DVI stay asleep (amber
LED). Sleeping from and/or waking to a non-X virtual terminal (eg, Ctrl-Alt-F1)
does not restore the display, nor does switching after waking. The laptop is
responsive, keyboard backlight comes on, and I can type `sudo reboot` into a
terminal that I left focused before sleeping, and the laptop shuts down and
reboots, with the display working after reboot. 

Attached is messages.log of the sleep (first line), and the resume (line 35 or
so). Please let me know what additonal information is needed.

fwiw, this issue is still present in kernel 3.3.1 (Arch Linux) with
xf86-video-nouveau 0.0.16_git20120210.

Is this still an issue with the latest software?

I have the same issue on MacBook Pro (mid 2009 - NV96 + NVAC), running on
3.13.0.0-git5.1. However laptop is not responsive after wakening: fans don't
go
on, no keyboard backlight... It seems the computer is still sleeping; I'll
try
to ssh it and post the results here.

Created attachment 89730
  --> https://bugs.freedesktop.org/attachment.cgi?id=89730&action=edit
3.13.0.0-git10.1 kernel log / suspend + resume

Adding 3.13.0.0-git10.1 kernel log, with suspend / resume / suspend /resume as
a sequence.

Kernel options were: nouveau.noaccel=1 nouveau.modeset=0 3
Results: computer is up and running, interactive but screen does not light up

I tried with only nouveau.noaccel=1 but boot hangs up after initialising the
nv96 card; it was working on kernel 3.11.x (though the screen was scrambled),
so I'll fill a bug report for this regression and see if I can bisect it.
Adding nouveau.config=NvMSI=0 changes nothing.

--- Comment #7 from Pierre Moreau <pierre.morrow at free.fr> ---
I've been playing a bit with the apple-gmux driver to check if it was the
one
responsible but without success; the only difference between before suspending
and after resuming being GMUX_PORT_SWITCH_GET_DISPLAY which used to be 24
before suspending, and equals to 0 when resuming (and the discrete card coming
back online, but that was already dealt with). So, without Nouveau loaded, the
screen will stay black.

However, if using patches from
https://bugs.freedesktop.org/show_bug.cgi?id=27501#c29, the screen resumes
correctly.

A friend tested on his MacBook Pro (Mid 2010) with an MCP89, running Linux
4.1.6 and it worked. Closing as fixed.
