Hi,

I tried the driver nouveau now that it is in Debian'sunstable.
It works very well except for one think : the monitor connected on the
DVI port stays blank;
This monitor shows the normal boot until gdm is starting (and nouveau
kernel driver I guess).

This works perfectly with the good old nv driver.

What's strange is that it seems that the kernel detects a DisplayPort
port instead of a DVI port. BTW the name of the port is DP-1.

I use a laptop with an integrated nVidia card :
01:00.0 VGA compatible controller: nVidia Corporation G98M [Quadro NVS
160M] (rev a1)

It's in the NV50 series.

I use Debian's kernel image 2.6.32-4-686-bigmem version 2.6.32-11. This version has drm from 2.6.33.

I didn't try newer kernel images or nouveau drivers. Please tell me if
this would be useful.

It could be related to bug 26797.

Thanks !

Dmesg boot log

Comment 2 Ben Skeggs 2010-04-29 16:02:30 UTC

Your laptop's video bios is reporting LVDS, VGA and 2xDP connectors.  Is the "DVI" port on a docking station?  If so, this makes sense as there's probably docking stations with DP connectors instead.

In any case, I pushed several fixes to nouveau git yesterday, one of which should probably fix your issue.

It'd be useful to see verbose (load drm module with debug=1 option) logs from nouveau git if things still don't work correctly.

Comment 3 Cyril Brulebois 2010-04-29 16:48:12 UTC

If that's the libuevent thingy, we probably could cherry-pick that one without having to worry too much about the possible ABI issues and put that in the Debian package. Julien, we can arrange some testing if you like (private mail to me will do the job).

Comment 4 Ben Skeggs 2010-04-29 16:51:01 UTC

No, it's specifically 2cf43e3fa8b2de237908b6b0b24e42003e94f1db "drm/nv50: fix monitor detection on certain chipsets".

Comment 5 Cyril Brulebois 2010-04-29 16:54:22 UTC

Christopher just pointed me to it in the meanwhile, sorry for the noise. I guess we'll have to wait for it to pop up in some stable updates, or point our kernel people to that patch.

Comment 6 Julien Wajsberg 2010-04-29 23:34:58 UTC

You're right, the DVI port is on a docking station, so this makes sense.

I'll see with Cyril how I could test this. Thanks !

dmesg with debug output for the drm module

Comment 8 Julien Wajsberg 2010-04-30 10:41:26 UTC

I managed to backport the change to Debian's current kernel.

I had to apply also changeset d62823c984102a6f96df147a65bf1ffa7acaef1d "drm/nv50: store full dcb i2c entry from vbios", and to change some minor things, but I think I applied it correctly.

But I still get the same bug.

I attached the log for dmesg with debug output for drm, as you suggested.

Thanks.

Comment 9 Ben Skeggs 2010-04-30 19:53:54 UTC

Ah sorry!  Can I get debug=15 instead.

As requested.

Comment 11 Ben Skeggs 2010-05-03 15:47:00 UTC

According to your log you have 2 external displays plugged in (VGA-1, DisplayPort-1), as well as your laptop's panel (LVDS-1).  The card only has 2 CRTCs, so can only bring up 2 displays.

Comment 12 Julien Wajsberg 2010-05-04 04:29:25 UTC

LVDS-1 is closed; in nv, it means it is disconnected. Please see xrandr outputs below.

Also, I tried the following command lines :
xrandr --output LVDS-1 --off
xrandr --output DP-1 --auto

-> nothing happens. Screen DVI-1 is still blank.
Then I open the laptop and issued :

xrandr --output LVDS-1 --auto

I got : 

xrandr: cannot find crtc for output LVDS-1

It means that it tries to display on both DP-1 and VGA-1, right ?

BTW, in gnome's display preferences, I correctly get both monitors displayed, but still, the monitor on DVI stays blank.

Again : I have no monitor on DisplayPort (and I have no DisplayPort on the docking station). I have one monitor on VGA and one monitor on DVI (and LVDS as well, which is off most of the time).

Thanks

I don't recall nv (unless by nv you mean the proprietary driver) doing anything of the sort.  In any case, nouveau does something similar in this case, hence LVDS being reported as "unknown connection".  We do this instead of "disconnected" so that X will setup LVDS still if the lid is closed and nothing else is plugged in.

Right, so now you're probably hitting another bug I've seen reported in a few places where docking station DVI fails on systems where it could be either DP or DVI on the docking station.

As I mentioned above, the VBIOS reports the connectors as DisplayPort as the docking station could potentially have DP instead of DVI-D connectors.  There's no way for us to tell which the manufacturer wired up, so we assume it's DP.  This has no effect on functionality.


Ok, my question for you is:  Are you able to make your VBIOS setup the DVI display during POST instead of the LVDS panel?  There may be options in your BIOS setup to allow this.  If so, let me know and we may be able to get traces that'll help me track this problem down for you.

Ben.

Yes, and that's good.

So that's ok :-)

That is my current set up: BIOS POST and Linux kernel messages are shown on the DVI display until nouveau is loading.

Ah, great!  In that case, can you boot with "nomodeset 3" so you're at a VGA text console and get some VBIOS traces for me?  Instructions on grabbing vbtracetool are at http://nouveau.freedesktop.org/wiki/DumpingVideoBios

I'll need:
./vbtracetool -2 2>vbios.rom
./vbtracetool -lp 2>post.iolog
./vbtracetool -dp 2>post.log (this will possibly take several minutes to complete)

If you could "bzip -9" those, and mail to mmio.dumps@gmail.com I'll take a look when I get a chance and see if I can find the missing magic.

Comment 16 Julien Wajsberg 2010-05-05 00:14:16 UTC

Is it sufficient to boot with nomodeset=3 and be in a text console, with X loaded ? Or should I boot single to not have X at all ?

Look more closely, it is "nomodeset 3", not "nomodeset=3" :)
The "3" will cause your system to boot to runlevel 3, which doesn't start X server.

Comment 18 Julien Wajsberg 2010-05-06 02:47:28 UTC

Oh you're right ;)

(except that it's not true everywhere)

I'll do whatever I must do to boot without X. But not until monday, so please try to sleep. :-)

Comment 19 Seth Rosenblum 2010-11-15 09:43:24 UTC

I'm also having this issue, with kernel 2.6.35 and xorg version 7.5. My nVidia card is the same (Quadro NVS 160M).

The DVI response on my docking station is identical to the response I get when I'm plugged in directly to the DP on my laptop or my dock.

Is there any additional info I can provide to you all to help this along?

Thanks

Comment 20 Seth Rosenblum 2011-01-06 11:15:56 UTC

I'm not sure if this is helpful, but it looks like Redhat fixed this same bug:

https://bugzilla.redhat.com/show_bug.cgi?id=532711

Not sure if that made it upstream or not.

Comment 21 Jörn Engel 2011-12-06 20:08:36 UTC

I have the same problem on and off.  If it hits me, the notebook display goes blank for X.  Having to drive to the office so I can actually see my desktop kinda sucks.

System is debian with 3.0.0-1-amd64.

Comment 22 Ilia Mirkin 2013-08-19 15:01:58 UTC

Is this still an issue with the latest kernel?
