Kernel log with nouveau built from git

Ctrl+Alt+Fn switches to virtual consoles but the display is blank although the
keyboard works. The backlight _is_ on. 

The console works OK up to the point when X starts. 

video=1280x1024 is specified in the kernel boot line in GRUB otherwise KMS
switches to something like the TV resolution (720x576) before X starts and X
starts at 1024x768.

It appears that there are some bits left from the blob
(/usr/lib/xorg/modules/extensions/libglx.so), and the xorg.conf is not setup
correctly (you should use, nouveau, rather than nv/vesa).

Have you gone through the TroubleShooting [1], namely sections 3 and 8

Oh dear, how embarrassing.

I _thought_ I had gone through section 3, but I had done it on the wrong
instance of Arch... I had not removed the nvidia-173xx-utils package on the
test instance.

I also didn't realise I even had the vesa driver installed.

So the problem is now resolved.

And now I know what RandR does, and how to disable the TV out in xorg.conf.

Again, many apologies fot the time wasted..

An mmiotrace from the blob would be useful to fix that (see [1] and [2]). Do
you have access to a TV?

The GUI resolution when X starts is fixed by having the proper drivers and an
xorg.conf that specifies the resolution I want.

The consoles are still not using the full screen though - about a 720x576 sized
patch in the top LH corner of the screen. Smaller than the TV-1 when that was
overlayed on VGA-1

Do you just want an mmio trace that covers the point when the Kernel switches
from VGA to 720x576, or do you want one that covers X starting as well? 

And I don't have access to a TV. Actually, since there's nothing connected to
the TV (S-video?) connector I don't understand why the driver is using it in
the first place. It doesn't use the DVI connector which also has nothing
connected to it.

Right, that's why an mmiotrace from your card would be useful. If you're
interested on fixing it you could:

 * Start tracing (the details are described in the links I posted
   in my last comment).

 * Start X with the nvidia proprietary driver (IOW the "blob"),
   but before, put the following in your xorg.conf, 'Section "Device"':
> Option "UseDisplayDevice" "TV"

 * Stop tracing and send the compressed results to mmio.dumps at
   gmail.com.

I'm currently on Xorg 1.8 and apparently the NVIDA driver is not supported by
that version of Xorg (which is why I'm using nouveau in the first place). For
the purposes of getting a trace will it be OK to use Xorg 1.8 or should I
downgrade to 1.7?

No big deal, but if I need to downgrade it will have to wait until I can have
unfettered access to this PC for a few hours - which will not be till the
weekend at the earliest.

Ok, could I also have a look at your VBIOS [1]? It might be enough to fix it.

Nothing suspicious in it, so yeah, a full mmiotrace would be more useful.

If you can load the nvidia kernel module it might be enough to do this to get a
trace (instead of starting X):

mknod nvidia0 c 195 0
cat nvidia0

I don't think so, we need to catch it while it's trying to detect TV.

You could start X with the "-ignoreABI" command-line option (or set it
somewhere in xorg.conf).  I'm guessing that if X works with this option, the
trace will be useful.

Turned out I only had to downgrade the kernel from 2.6.34 to 3.6.33. I've
emailed the trace to mmio.dump at gmail.com. It's also available at:

Thanks. It turns out that the blob's also detecting load in your TV output:

R 4 195.041175 1 0xfc682608 0xf0001000 0x0 0
                              ^
So most likely someone screwed it up when the board was assembled: We can do
nothing besides skipping load detection for your specific card. Can you provide
the output from "lspci -vvnn"?

Output of lspci -vvnn

Ouput of lspci -vvnn attached.

TBH now I've installed this card in my Windows machine I'm undecided whether
the false load detection is a bug or a 'feature'. The Windows installer fires
up a configurator after it's loaded the driver, and the first thing it tells
you is that you probably don't want the card configured as it is! It
initialises in the same mode the nouveau driver does 'Clone' with both TV and
VGA enabled and one overlaid on the other. The difference is that the VGA is on
top so if you don't understand what the configurator is telling you and leave
it alone no harm is done visually - so long as you really haven't got a TV and
no monitor - but maybe it can detect no monitor - I don't have a TV so can't
test that scenario. It also avoids the 'you must have xxx installed before you
can configure the driver' syndrome you often get with multi-function printers.

The xorg.conf Option lines added by nvidia-settings to disable TV don't work
for nouveau, but 'xrandr --output TV-1 --off' does work for X.

See [1], 'Option "Ignore"' is what you were looking for, but you shouldn't need

Thanks for the patch. Building a Linux kernel seems to be a complete nightmare
unlike NetBSD where its very easy. I'll give it a go once I've figured out how
its done -and why it seems so complicated.

I'd found 'Option "Ignore"' at [1] just after I'd added the output of lspci.

I've built a kernel incorporating the nv34_tv_detect_quirk patch and it now all
works as it should - KMS wsitches to the monitor's native resolution of
1280x1024 as the module is loaded at boot, the virtual ttys use the same
resolution, and there is no need to turn TV-1 off before starting X, or use the
"Ignore" option in xorg.conf.
