can't start X after install

I have installed OpenSuse 11 x64 and it appears to be fine, but when suse start for the first time my computer can’t start x. I have tried sax2 -r -m 0=vesa and sax2 -r -m 0=nvidia and I get an error that my computer have no screens. So I can’t simply start x.
I think that maybe this is because my graphics card.
I have upgraded my desktop as follows:
Intel Quad Core 2.8 FSB 1333
4 GIGS DDR3
Motherboard XFX Nforce 790i Ultra
Videocard Geforce 9800 GX2 (I think this is the problem)

Anyone can helpme?>:(

You say AFTER you installed? Or was the install incomplete?

If after you installed, then there likely was a functional xorg.conf for part of the install.

What happens if you boot to run level 3, log in as a regular user, then type “su” (no quotes) to get root permissions.

Then type:
cp /etc/X11/xorg.conf.install /etc/X11/xorg.conf
to replace your xorg.conf with the install one.

Then type “exit” to get rid of root permissions (that is IMPORTANT).

Then type “startx”.

If it works, then open a gnome-terminal or kde konsole and type:
su -c ‘shutdown -r now’ to reboot or
su -c ‘shutdown -h now’ to halt.

Note in cases like this, it can also be useful to select an install at a lower resolution, or even select a vesa install.

Well I assume this was after install, when suse is going to do the first login usung the gui.

Tried what you recommend and nothing. This is the error:

*(==)log file: “/var/log/Xorg.0.log”, time:wed nov 26
(==)using config file: “/etc/X11/xorg.conf”
(EE)open /dev/fb0 :No such file or directory
(EE)screen(s) found, but none have a usable configuration

Fatal server error:
no screens found
giving up
xinit: conection refused (errno 111): Unable to connect to X server
xinit: no such process (errno 3). server error*

I have tried installing with a lover resolution or vesa as you recommend and the same error. I tried an installation using repositories for xorg as you recommended into another thread and i still get the same error.

It appears you have 2 video device?

Boot to an ascii prompt (type “3” in the grub menu) and then login as a regular user.

Then type:
sax2 -p
This will tell you if the video card you wish to install to is chip 0 or chip 1.

I’m thinking now you wish to try “chip 1”.

In which case, then type:
sax2 -r -m 1=vesa
or
sax2 -r -m 1=nvidia
or
sax2 -r -m 1=nv

and as soon as one of those appears to have exited naturally to the text ascii/prompt, type “exit” to get rid of root permissions. Type “whoami” to confirm you are a regular user.

And then type “startx” to test X windows.

If that works, then open a gnome-terminal or a kde konsole and type:
su -c ‘shutdown -r now’ #enter root password when prompted to reboot.

If you don’t use both cards you can disable the one on the motherboard in BIOS

I’m using a dual chip videocard. It’s just one videocard. The geforce 9800gx2 use 2 chips 9800gx. So i don’t think I can disable one.

When I type sax2 -p this is what i get:
Chip: 0 is –> NVIDIA GeForce 9800 GX2 03:00:0 0x10de 0x0604 AGP nvidia
Chip: 1 is –> NVIDIA GeForce 9800 GX2 04:00:0 0x10de 0x0604 AGP nvidia

but this is weird. the card is PCIExpress and here is noted as AGP.

And i’m still having no x. The only way I can login using x is at grub as follows:
x11failsafe vga=0x31a
>:(

By now I have tried
sax2 -r -m 0=nvidia 1=nvidia -c 0 1

And appears to be working but after a while appears the same error and nothing. Still can’t start X.
