11.04 NVidia Problem

[heisters]

Thanks for the tips, @ scampbell70. I tried something dumber and simpler, but along the same lines, and it seemed to work:

1. At the grub menu, select recovery mode
2. At the recovery menu, boot into FailsafeX mode
3. You'll get some warning about no graphics support, Unity won't boot, you'll end up in classic mode
4. Go to Administration > Additional Drivers
5. Remove the "version current" Nvidia driver. It should already be deactivated, be sure to remove it.
6. Re-enable the "version current" Nvidia driver. You shouldn't need to restart or anything before this step.
7. It will download and re-install the Nvidia driver, presumably reinstalling the kernel modules and whatnot
8. Restart
9. Boot normally into Unity
10. Enjoy

Worked for me, at least.

Hi,
I tried the same but got GCC compiler version mismatch error, no luck even after clicking ignore this mismatch.
Installation failed.

The suggestion scampbell70 suggests worked for me on 10.04 last year. I did a clean install of 11.04 and Nvidia drivers loaded by ubuntu actually worked and stuck this time. My card is the 7000m (notebook)

Thanks Heisters,

had the same problem and your way worked also for me.

I installed the proprietary driver using the command line procedure of scampbell70, reinstalled the ubuntu-desktop that was removed during the purge and now have Classic with 3D acceleration. Reinstalled ubuntu-desktop but no unity. I now think that it is just some compiz settings that are not correct as playing around with System > Preferences> CompizConfig Settings Manager got the side menu to display. So eventually, that procedure may work.

I did, however, look at the Additional Drivers. Hmmm. It says that no proprietary drivers are installed and has both 173 and Version Current grayed out. There is also no option for removing either. I think I read in the buglist somewhere that Additional Drivers is not accurately reflecting the true driver situation. I would take what it is describing with a bit of caution.

I have a similar problem. I did a fresh install of 11.04 and after installing the proprietary drivers I get this error:

[ 23.961] (EE) NVIDIA(GPU-1): Failed to initialize the NVIDIA GPU at PCI:2:0:0. Please
[ 23.961] (EE) NVIDIA(GPU-1): check your system's kernel log for additional error
[ 23.961] (EE) NVIDIA(GPU-1): messages and refer to Chapter 8: Common Problems in the
[ 23.961] (EE) NVIDIA(GPU-1): README for additional information.
[ 23.961] (EE) NVIDIA(GPU-1): Failed to initialize the NVIDIA graphics device!

I can only manage to get the nvidia drivers to load if I first boot into recovery mode and then restart X. But after I reboot/shutdown the problem comes back again.

I've tried all sorts of things in this thread and others with no success. Any help?

I tried installing the latest NVIDIA driver with the kernel source of 2.6.38.8 and also 2.6.38...still I'm getting the below error,

ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most
frequently when this kernel module was built against the wrong or
improperly configured kernel sources, with a version of gcc that differs
from the one used to build the target kernel, or if a driver such as
rivafb, nvidiafb, or nouveau is present and prevents the NVIDIA kernel
module from obtaining ownership of the NVIDIA graphics device(s), or
NVIDIA GPU installed in this system is not supported by this NVIDIA
Linux graphics driver release.

Please help me, how can I identify the correct kernel source to download. I downloaded 2.6.38.8 thinking my 11.04 is having that.. that dint work with nvidia..
Then I downloaded 2.6.38 source from Synaptic.. even that dint work..

Cool method scampbell70. Took some twiddling here and there but in the end your method worked just fine.

Nvidia drivers is running smoothly and much more stable than the 3D one I got working earlier.

Cheers,

Raz.

This worked for me also, thanks Heisters!

The easiest solution is

sudo apt-get install linux-headers-`uname -r`
sudo dpkg-reconfigure nvidia-185-kernel-source

If you're just upgrading from 10.10 to 11.04
