           Summary: displayport: x server does not draw anything on ThinkPad
                    T410
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

dmesg when DP-1 is plugged in

This happens when booting with an external monitor attached to Displayport on
ThinkPad T410.

After loading nouveau.ko the main display on LVDS-1 switches to hi-res
framebuffer (KMS) like during normal boot. But when X is started, it switches
to vt7 and then nothing happens - neither is the frame buffer is redrawn
anymore, nor the external display is enabled. This is not a lockup, though. I
can switch back to vt1 with ctrl-alt-f1, and I can login into the x session by
blindly typing username/password (though xdm) or start gtk-demo from vt1. (Same
happens if I just start X with "X -wr&" .)

[in brief]

xorg.conf:
----> snip ----->
Section "Device"
        Identifier  "Card0"
        Driver      "nouveau"
        VendorName  "nVidia Corporation"
        BoardName   "NVIDIA Quadro NVS 3100m"
        BusID       "PCI:1:0:0"
EndSection
<---- snap <-----

steps to reproduce:
 - boot and load nouveau.ko
 - start X with "X -wr -config ./xorg.conf&"

result:
 - KMS console works, but
 - X stops redrawing the frambuffer switching to vt7 does not change the screen

expected:
 - KMS console works
 - X draws a blank white screen on LVDS-1 (in vt7)
 - xrandr can enable DP-1


[notes]

kernel reports several:

The first obvious thing to tackle is the unknown init table commands.  I've
seen another case where these are used, and should have my hands on a laptop
that has them at some point in the near future, so I'll tackle them then.

In the meantime, it'd be very useful to grab a mmio-trace of the nvidia binary
driver initialising your displays as another data point.

http://nouveau.freedesktop.org/wiki/MmioTrace has detailed instructions how to
grab one.

dmesg output on macbook pro

I see the same problem here with a MacBook Pro and a display connected to the
mini DisplayPort via a mini-DP<->VGA adapter. Attaching kernel log, fwiw. The
bits about not being able to get the EDID are the same as the original
reporter. Happy to help test/debug.

Hardware: Thinkpad T410, NVS 3100M (nva8?)
Kernel: vanilla 2.6.39+ from kernel.org + nouveau tree merged

Displayport still is not working if not activated by BIOS (xranrd claims that
the CRTC is in use, but there is no signal on the display).

The mentioned xorg hang disappeared long time ago (in my case at least)...

I have the same issue on a Thinkpad W510; the display is supposed to be active,
but I don't see anything on the screen.

I am sorry, just tried to install fedora15 on my T410 and could not continue
the install after reboot, because DP was plugged in and xorg would hang
infinitely.
(machine worked fine though, had to install the blob through USBtty, though
:-()

what I want to say, this bug is still there in stable releases, my post from
the last time was from gentoo and everything installed from git...

btw. will DP be useful at any time, or is this a hard to reverse engineer BIOS
issue?

> I have the same issue on a Thinkpad W510; the display is supposed to be active,

on git versions: If I close the lid then will BIOS disable LVDS and enable DP,
which then works as expected in xorg, you can even enable LVDS afterwards - so
maybe this can work for you until this bug is fixed...

It's not the same bug.  This bug is about DP outputs not working unless
initialised by the VBIOS.

Is it possible that the bug 34429 causes the same problem - uninitialized eDP
output after suspend and resume?
