3 Attachment(s)
NVIDIA 8400M G, ASUS A7S, Core 2 Duo, Kubuntu 8.10

I successfully intalled 180.22 with
sh NVIDIA-....run -k $(uname r)

But, when i make a restart it quites with BLACK screen saying s.th. like:
Checking ... state ...

I switched to ctr + alt + F1, stop kdm

/>/etc/X11/kdm stop
/>edit xorg.conf

change in "Device" section "nvidia" to "vesa" i am able to restart kdm
and have kdm working. So, what does i forget to configure? You can see below my log and xorg.conf files.

/>modprobe nvidia
tell me -> "No such device" ...

(17" laptop screen (normal resolution is 1440 x 900))

Re: NVIDIA 8400M G installation fails
I just ran into a similar scenario with an Nvidia GeForce 7000m for my Acer aspire 5520 laptop. The sh command finally got the installation going without errors, but X won't load upon init 5 or system reboot.

It stays blinking over and over trying to load the graphics driver but then it stays blank.

My system is Fedora 12 i386. It seems to come preloaded with some nouveau or nouveaufb video driver which even disables the default vesa and takes over.

Somehow it keeps interfering i guess with the nvidia driver and won't let it load.

Nvidia, any chance for an updated driver with new gcc and stuff so we don't run into trouble?

any ideas anybody? Thank you.

Re: NVIDIA 8400M G installation fails
This seems like a BIOS issue, ther'a a lot of this:

Jan 16 15:45:15 tiescha-laptop kernel: [ 1933.589062] NVRM: BAR1 is 0M @ 0x00000000 (PCI:0001:00.0)
Jan 16 15:45:15 tiescha-laptop kernel: [ 1933.589068] NVRM: The system BIOS may have misconfigured your graphics card.

in your logs. Try looking for an update at Asus' website.

Oh! How much RAM (like physically) does you laptop have?
OK, I got it from your dmesg, and it's 3GB, right? If so, then could you please try removing one of the sticks? Down to say 2GB, and retrying to start X?

[ 257.644701] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:
[ 257.644703] NVRM: BAR1 is 0M @ 0x00000000 (PCI:0001:00.0)
[ 257.644709] NVRM: The system BIOS may have misconfigured your graphics card.
[ 257.647107] nvidia: probe of 0000:01:00.0 failed with error -1
[ 257.647822] NVRM: The NVIDIA probe routine failed for 1 device(s).
[ 257.647826] NVRM: None of the NVIDIA graphics adapters were initialized!

First of all I'd try with the newest available driver to see it works as expected.
If that doesnt work, I'd try changing some BIOS settings, and as a last resort I'd check for a BIOS update.

Re: NVIDIA 8400M G installation fails
Guys, the answer seems a lot simpler than we though, at least for my case.

Apparently there is a compatibility issue between the nvidia drivers and the default nouveau driver used by the fbcon on Fedora 12 and others similar, preventing the Nvidia proprietary driver to work even after it is properly installed with the -k $(uname -r).

There are 2 ways of dealing with it:

1. change the default initrd:

su -
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)

2. keep the original initrd, but disable the nouveau driver:

edit /etc/grub.conf and add the following to the end of the line(s) starting with 'kernel':

#2 worked flawlessly for me, the complete reference can be found on the following links:

Good luck !
