Unknown DCB 1.5 entry, please report

[c_ellesley]

Binary package hint: xserver-xorg-video-nouveau

Starting X-Server fails with the Error:
"Unknown DCB 1.5 entry, please report"

I am using a geforce2 compaq AGP-card with one sole DVI-port and a HP-Flatpanel 1920x1200
card-id is 10de:0111 (rev 2b)
i'm using Jaunty 1:0.0.10~git+20090404+11be9a9-0ubuntu1

unfortunately the errormessage doesn't contain the DCB-entry and i don't where to get it.

Each time I try to start ubuntu with nouveau i see yellowish-reddish flicker (horizontal lines) and i once got a glimpse of the ubuntu-startup logo before it gives up.

(notice on the sidelines: the nvidia-driver didn't get the colors right on my card two years ago - i'm using nv since)

thank you very much for your efforts getting all the old hardware running - great!

Hi archelegraph,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

I compiled nouveau and changed nv_bios.c where dcb1.5 is parsed, to let my dcb-entries be accepted :
Line 4343:
{ if (conn != 0xf0003f00 && conn != 0xf2247f10

/*these two where added */ && conn != 0xf0007f00 && conn != 0xf2205002 &&

     conn != 0xf2204001 && conn != 0xf2204301 && conn != 0xf2204311 && conn != 0xf2208001 && conn != 0xf2244001 && conn != 0xf2244301 && conn != 0xf2244311 && conn != 0xf4204011 && conn != 0xf4208011 && conn != 0xf4248011 &&
     conn != 0xf2045ff2 &&
     conn != 0xf2045f14 && conn != 0xf207df14 && conn != 0xf2205004) {
  NV_ERROR(pScrn, "Unknown DCB 1.5 entry, please report\n");

  /* cause output setting to fail for !TV, so message is seen */
  if ((conn & 0xf) != 0x1)
   dcb->entries = 0;

  return false;
 }

I was hoping it would work without further ado - well no it doesn't, but maybe the xorg.log is interesting for you:
-there are two dcb entries:

has a very similar problem, his bugreport is the following:

Video Card is a GeForce3 Ti 500

Using the nouveau driver in my xorg.conf I get a blank screen after booting the
system. (Text Console works)

Looking at Xorg.0.log the following lines are found

(II) NOUVEAU(0): BMP BIOS found
(II) NOUVEAU(0): BMP version 5.20
(II) NOUVEAU(0): Bios version 03.20.00.20

We've uploaded a new -nouveau to Lucid which should no longer be experiencing this problem.

[c_ellesley (archelegraph)]

I tried the Fedora 12 live CD (which uses the new nouveau by default) and it failed to set up my nv11 card - so I don't think the problem is solved. Unfortunately the error is now no longer obvious in the log
I bought a new nvidia card (nv44a type) and this one works fine with fedora.
