xorg.conf , nvidia (dual-monitor) and Ubuntu 11.10

Hi all!!

I just updated my version of Kubuntu to the 11.10 and i've got a big problem with my dual-screen settings.

After the upgrade (everything was right, no warnings or errors), i rebooted the machine and it didn't load graphical desktop/screen. I solved this problem easily, deleting the xorg.conf file.

So, i deleted completely nvidia drivers, updated and reinstalled including the xserver-xorg-video-all. I can open my desktop but, if i try to access the nvidia settings, it says that xorg.conf is not located in /etc/X11 (obvious error), and if I run the nvidia-xconfig it creates it. But then i need to reboot to load the new configuration and......the system gets stuck again. To access the graphical desktop, the only way is to delete the xorg.conf.

My question is: how to set the dual monitoring???? Why do the nvidia drivers (although updated and xorg.conf is deprecated) creates that file that causes the boot problem?

Please help me, i need the dual monitoring to work.

PS: i can't use "nouveau drivers" because, even if they properly work, they are really slow in my computer.

Are you opening nvidia-settings in the terminal? It needs root permissions to save the file.

Open terminal

sudo nvidia-settings

Then save to X configuration file after you get it set up.

Reboot and it should work.

Thank you for the reply.
Of course i was already operating as admin, otherwise i could not delete nor create files in /etc/X11.

But anyway I tried to do so:
1) I download from internet a preconfigured basic xorg.conf file. I used it and the graphical interface loaded!
2) Then I deleted the nvidia drivers (with the --purge option) and updated my repository to install the last stable release of the drivers (as explained here
3) I created the xorg.conf file using the nvidia-xconfig.
4) After rebooting i got the same error but i was able to explore it. It says:
FATAL: error inserting nvidia-current: no such device.
failed to load the NVIDIA KERNEL MODULE
No screen found.
But I'm using the last stable nvidia drivers and the linux kernel 3.0! They should be compatible!
Any idea?

The link you provided is not working.

I remember trying nvidia-xconfig on Debian Squeeze. It didn't work out well for me either. What I did was deleted the xorg.conf (Or better yet just rename it to be on the safe side.) Then I opened the terminal up and as root of course, I started nvidia-settings and simply saved the x configuration file, rebooted and it worked fine for me after that.

You can give that a try and see if it works that way.

I fixed the link, thanks for the advise!

I also tried your method with no luck. Here a screenshot showing that the display are not recognized at all from the "sudo nvidia-settings"

Solution from another forum:
1) remove all nvidia drivers from system: nvidia-* and nouevau drivers as well (e.g. xserver-xorg-video-nouevau) with apt-get remove
2) download new nvidia 290.10 drivers from nvidia ftp
3) shutdown laptop
4) set up BIOS: Graphics Device to Discrete Graphics. See recipe here, under topic Problems
5)start laptop
6) Ctrl-Alt-F1, login as root
7) stop kdm: service kdm stop
install nvidia drivers: sh
9) start kdm: service kdm start
10) login in kde
11) apt-get install nvidia-settings
12) setup 2nd monitor with nvidia-settings

Thanks to these steps, i got my dual screen back!!!

But in my case it wasn't enough. I had to download the file because my graphic card is not recognized by the version 290. It caused the conflict everywhere, even in the xserver-xorg files. Resuming, the steps I did are:

- remove everything about nvidia (sudo apt-get remove --purge nvidia-*)
- downgrade the drivers: xserver-xorg-core xserver-xorg-input-evdev xserver-xorg-input-mouse xserver-xorg-input-synaptics xserver-xorg-input-vmmouse xserver-xorg-input-wacom xserver-xorg-video-radeon
- install nvidia drivers: sh NVIDIA-Linux-etc...

The problem is that the uploader is always asking to upload the file i downgraded, and if i update them then i got stuck again with the same problem.

I hope this can help somebody!

my graphical card is GeForce FX 5200

Does anybody know how to disable the updating of specific drivers?
