GeForce FX 5700 - Digital DVI output turned off on boot, X11 does not see the output at all.

[MMlosh]

I upgraded to Raring and lost my digital video output.

The computer has "01:00.0 VGA compatible controller: NVIDIA Corporation NV36.2 [GeForce FX 5700] (rev a1)" video card.
The card has two connectors (VGA and DVI-I) and provides THREE video outputs (2x analogue, 1x digital)

The card's bios correctly detects which outputs are connected and uses them.
I can see BIOS and GRUB on digital.
But then the kernel boots and turns the DVI-I:Digital output off (and turns on DVI-I:Analogue)

I am planning to reinstall that machine, so I don't mind running unverified kernels on them.
Mainline kernel will be tested next.

I am unable to run apport (to get my sound configuration published as requested)
It's broken on Raring. ( #1150335 )

I browsed syslog & dmesg for any interesting info and found none.
I'll attach the actually necessary info as soon as requested.

[MMlosh (mmlosh)]

I tried a mainline kernel: mainline/v3.9-rc2-raring
It works.

[MMlosh (mmlosh)]

I ran that kernel and did
sudo apt-get update & sudo apt-get upgrade.
it did what was there to do....

..and left me in a root shell !
Or maybe both user and root shell fighting over the VT1 input.
Hitting Ctrl+D (crashed? and) rebooted the computer.
That is really weird and I further undermines my trust into kernel downloaded over plain HTTP. (no HTTPS, no signature)

PS: kernel 3.8.0-12 does not fix the issue

Can you also test the latest v3.8 stable kernel with is:

v3.8.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.4-raring/

[MMlosh (mmlosh)]

v3.8.4 turns the screen off.. The issue exists in there.

MMlosh, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

[MMlosh (mmlosh)]

Well..

This is what happens with 13.10's 3.11.0-13 kernel. (reboot after I installed it)
The screen goes dark (probably not off) for a couple of seconds after hitting enter in grub.
Then it goes back on, writing startup messages (first one is, strangely, starting SystemD login service)

I did a full power cycle..
the screen got dark for 12 seconds (I measured it this time)
and the first message displayed was what I expected (fsk message saying disk is OK)

(+ a different issue emerged: In both cases the SLiM login manager was started (incorrectly) on VT1. )

It's not perfect, but I guess it allows you to mark this issue fixed :)
