Nvidia module not loading

[Malfet]

Enabled the Nvidia restricted drivers through "Settings>Administration>Hardware Drivers"

I did it before and I follow your advice step by step now. No way. The problem is "Restricted drivers manager" just does not see graphic card. In Ubuntu 7.10 it was perfectly fine.

I have the same problem in kubuntu 8.04 with my video card nvidia 8800gts. I have the same problem from hardy alpha but the problem exist until today. I have can install gpu driver only with envyng

Well I got my nvidia driver working correctly. Fount out for some reason gutsy kernel was loading still even tho grub pointed to hardy kernel. Had to remove hardy kernel and reload the hard backup kernel. Now every thing is working correctly. Now to just get Compiz working again heh.

Would have been better off to do a fresh install of hardy instead of doing upgrade. Which I still might do.

I had the same problem. Fresh install of 8.04, downloaded the drivers from the nvidia site, installed them, restarted gdm. Everything worked, compiz, dual screen, the works.

Until I rebooted and X dropped me into low resolution. I spent some time troubleshooting, and I found out that somehow the nvidia kernel module was being loaded, but without the i2c_core that it depends on. You can check this by doing 'lsmod | grep nvidia'

Note: I did all this as root. Once I rebooted and my X wouldn't start properly, I went to tty1 (CTRL-ALT-F1) and stopped gdm with '/etc/init.d/gdm stop'. Once you're ready to start gdm again, use '/etc/init.d/gdm start'.

Right after you install the nvidia drivers, you'll get output like this:

root@ubuntu:~# lsmod | grep nvidia
nvidia 8858052 34
i2c_core 28544 2 nvidia,i2c_nforce2

If you give the same command after a reboot, you'll see that the i2c_core line is missing.

If you're in that situation, stop gdm, then give the command 'rmmod nvidia' and then the command 'modprobe nvidia'. Now you should have both lines again when you do an 'lsmod | grep nvidia'. Restart gdm, and you're good to go.

To make life easier on myself, I created a simple script in /etc/init.d that I called nvidia_workaround. The script looks like this:

#!/bin/bash
/sbin/rmmod nvidia
/sbin/modprobe nvidia

do a 'chmod u+x /etc/init.d/nvidia_workaround' to make it executable, and an 'ln -s /etc/init.d/nvidia_workaround /etc/rc2.d/S02nvidia_workaround' to get the the script to run automatically during boot.

Now, when you reboot, your nvidia driver will load properly.

I'm sure there's a nicer workaround to get the module to load properly, but it's late over here, and I'm off to sleep

I did an upgrade to hardy had the low resolution warning went to throw in my backup xorg file with a sudo command learned I couldn't sudo anything because of bad host name. I troubleshot that for a bit got that working but still no luck with nvidia drivers. I tryed envy uninstall and reinstall tried both nvidia-glx and nvidia-glx-new no luck with anything. I will try the tips on here tomorrow but I have to goto bed unhappy tonight

can u explain it? Pls

SOLUTION! (At least from me). I picked most of these actions from some other posts. Here is what I did:
1) I un-installed any drivers I had installed with EnvyNG.
2) Re-installed the restricted drivers per a suggestion in another post.
sudo apt-get install --reinstall linux-restricted-modules-$(uname -r) nvidia-glx

3) Installed the following modules as suggested by apt during the reinstall.
sudo apt-get install nvidia-kernel-source nvidia-settings

4) Rebooted
5) Enabled the Nvidia restricted drivers through "Settings>Administration>Hardware Drivers"
6) Rebooted
7) My usual resolution worked again! - Driver 169.12
8) Turned on Compiz-Fusion
9) Used Nvidia settings program I enabled both switches for "Sync VBlank"

Now Compiz-fusion, Awn and video play back are working again.

Next challenge is to getting my sound working again.

step 3 is not working i get this

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting nvidia-new-kernel-source instead of nvidia-kernel-source
Package nvidia-settings is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package nvidia-settings has no installation candidate

I manage to solve it. I just removed all traces of drivers by Envy and then Synapric and try to reinstall again NVidia driver NVIDIA-Linux-x86-169.12-pkg1.run and then.. it worked!

1.

sudo chmod +x NVIDIA-Linux-x86-169.12.pkg1.run

2. CTRL+ALT+F1
3. Login
4.

sudo killall gdm

5.

sudo ./NVIDIA-Linux-x86-169.12.pkg1.run

6. Ignore warning about non-compartible compile module
7. Restart system and activate "standart" visual effects.

Compiz is working, just in 8.04 I don't have access to it throuth desctop setting, but only from the main menu. All eye candy do as well.
Only problem, Logitech web-cam started to work in Hardy after installation (it did not work in Gutsy) now stop working again... Dunno what is the problem between NVidia and webcam.

I have had very similar problems, but finally found a solution.

It turned out that for some reason the menu.lst wasn't updated during the upgrade to Heron,

That meant that the old 7.04 kernel was loaded, I modified my menu.list file /boot/grub/menu.lst

sudo gedit /boot/grub/menu.lst

title		Ubuntu 8.04, kernel 2.6.24-16-generic
root		(hd0,0)
kernel		/boot/vmlinuz-2.6.24-16-generic root=UUID=29d77fb9-9cd5-4ef7-be76-b9038f8746ff ro quiet splash
initrd		/boot/initrd.img-2.6.24-16-generic
quiet

title		Ubuntu 8.04, kernel 2.6.24-16-generic (recovery mode)
root		(hd0,0)
kernel		/boot/vmlinuz-2.6.24-16-generic root=UUID=29d77fb9-9cd5-4ef7-be76-b9038f8746ff ro single
initrd		/boot/initrd.img-2.6.24-16-generic

having done that I installed the nvidia-settings module

sudo apt-get install nvidia-settings

rebooted the machine

and ran System->Administration->NVIDIA X Server Settings

once that was done, every thing worked like a dream.

So it turned out that the real problem - for me - was that the grub menu wasn't updated during the upgrade process.

IMHO the problem is related to restricted-modules.
Like many others I have problems with my previuosly (in 7.10) working Nvidia card; when X fails to start and goes in failsafe mode, I can see in the log this error:

API mismatch: the NVIDIA kernel module has version 72.86.04,

but thie NVIDIA driver component has version 169.12
