no screens found

Binary package hint: xorg

I've tried this a few times, and waited for updates to perhaps fix it, but now I'm growing impatient and would like to finally play with Intrepid.

I install intrepid, nothing special. I boot it up, and X won't start. I tried installing nvidia-glx-177, -173, -77, and also the 169, 174, 177, and 180beta binaries from nvidia.com. They all give me the same result: "no screens found" in my /var/log/Xorg.0.log

Attached will be my Xorg.0.log and xorg.conf

I'm using 2 video cards with no integrated video. I built my PC. The motherboard is an XFX 680i LT SLI motherboard, running a nvidia 7900GS KO and a nvidia 6500. I'm not trying to enable the second videocard yet, just trying to get video working. Hardy works fine, I've never been able to use Intrepid.

Here is my xorg.conf

I had a similar problem once with my old Dell Inspiron and this one fixed it for me:

http://ubuntu-austria.at/viewtopic.php?t=358&highlight=crash+installation

if you don't know German, after a failed start of X, you go to console and type

sudo apt-get install xorg-driver-fglrx
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv
startx

and if you are still on live CD, you have to do it twice (once for the live CD and once for your real install).

Those are for ATI video cards, I'm using nvidia.

[Bernhard (b.a.koenig)]

Sorry, missed that. Did you post in your original report which nvidia card you are actually using?

(!!) More than one possible primary device found
(--) PCI: (0@1:0:0) nVidia Corporation G71 [GeForce 7900 GS] rev 161, Mem @ 0xcc000000/0, 0xb0000000/0, 0xcd000000/0, I/O @ 0x00009c00/0, BIOS @ 0x????????/131072
(--) PCI: (0@3:0:0) nVidia Corporation GeForce 6500 rev 161, Mem @ 0xc9000000/0, 0xa0000000/0, 0xca000000/0, BIOS @ 0x????????/131072

Your /var/log/Xorg.0.log states that you have possibly more than one video card, can you try to disable the integrated video card in your BIOS to see if that changes anything?

If I am barking up the wrong tree can you please post more clear system information such as Vendor (if you didn't build it yourself), Motherboard vendor and model (if you did).

Are you currently using Intrepid? Do the graphics work for the live cd? Did you need to use an alternate.iso to install?

Also have you tried running: sudo dpkg-reconfigure xserver-xorg

Thanks for further information.

[dmsuperman (dmsuperman)]

Sorry, added more details.

I forgot to mention in my edit: I use the alternate install disc to install.

[Chris Crisafulli (itnet7)]

I noticed that you said that hardy works fine, does that mean that you are dual booting, both Hardy and Intrepid? I am wondering if you still have your xorg.conf file that was working fine from Hardy? If you back up your current non-working xorg.conf file and bring over the one from Hardy to intrepid, does this solve your problem?
Another thing to try would be to remove the card you plan to use as your secondary, and get the single primary card working successfully. Then re-introduce the other card.

I am not sure that this truly a bug with xorg, I am pretty sure that when you want to try and run this type of a configuration you pretty much need to manually edit your own xorg file in order to get your desired results. Meanwhile I will be looking into it a little more.

If you have access to the older xorg.conf and you try using it and it works, or if you try the other idea I presented and it does, then I think we should mark this as invalid.

These instructions solved my problem entirely.
I have a similar bug: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/307073
Though I think mine is SLI related, since Xorg didn't know what to do with two GPUs.

[QUOTE=Cambo;6082619]I was having the same problem of X not starting up after installing Intrepid. (We won't go into the mess that was created trying to upgrade Hardy :/ )

The answer I ended up working out was to add a Busid entry in the Device section of my /etc/X11/xorg.conf file.

To find the correct Busid, I used;

    sudo lspci | grep VGA

The output I got from this was;

    01:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7600 GT] (rev a1)
    04:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7600 GT] (rev a1)

(Yes, SLI :D )

So, I then edited the Device section of my /etc/X11/xorg.conf to read as follows;

    Section "Device"
 Identifier "Configured Video Device"
 Busid "PCI:1:0:0"
 Driver "nvidia"
    EndSection

A quick;

    sudo service gdm restart

and I was greeted by X running at the maximum resolution of my LCD monitor.

Hope that helps one or two of you.
