Serious problems with nVidia proprietary driver installation on 64-bit Kubuntu 12.04

[oshunluvr]

Try loading the nvdia driver again, When you're dumped to the terminal, try:

sudo echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
sudo echo 1 > /sys/bus/pci/rescan

And then restart kdm -> sudo service kdm restart
Report back your results. Also, I've read the problem doesn't exist in the 32bit kernel. I know you've already done a bunch of re-installs. Do you have room for another install partition so you can fresh-install there instead of wiping this one every time?

Do you mean installing the driver again?

Do you have room for another install partition so you can fresh-install there instead of wiping this one every time?

Not really to be honest.

[oshunluvr]

Not installing, unless you removed it. The only way we can test it is to use it - I know it's a PITA but no other way.

If you use an /etc/X11/xorg.conf file you can usually change drivers without uninstalling each one.

[Caesar]

Well, I have never succeeded booting KDM with nVidia proprietary driver on 12.04, so yes, I did have to remove it every single time.

O.K., here is what I get on a fresh (!) Kubuntu installation after I download and install the recommended nVidia proprietary driver via Additional Drivers tool.

1) lsmdo | grep nvidia

nvidia              12319264  0

2) lsmod | grep nouveau - no output.

3) dkms status

nvidia-current, 295.40, 3.2.0-30-generic, x86_64: installed

So the driver seems to be properly installed, but still I'm stuck with a console...

4) sudo echo 1 > /sys/bus/pci/devices/0000\:01\:00.0 /remove

sudo echo 1 > /sys/bus/pci/devices/0000\:01\:00.0 /remove is a folder

5) sudo echo 1 > /sys/bus/pci/rescan

sudo echo 1 > /sys/bus/pci/rescan - access denied

6) sudo service kdm restart

kdm stop/waiting
kdm start/running, process 2120

The output seen in points 4) and 5) I had to translate from Polish to English, so I'm not sure if they are exactly the same as in originally English Kubuntu installation.

[oshunluvr]

sudo echo 1 > /sys/bus/pci/devices/0000\:01\:00.0 /remove

Looks like you put a space before /remove

Your polish/english translation looks fine.

[oshunluvr]

NOTE: I tried these commands on my system, and I also got "Access Denied"

You have to do it this way:

sudo -i
echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
echo 1 > /sys/bus/pci/rescan

[Caesar]

Utilizing command sudo -i I was finally able to execute the other two commands You gave, but after restarting kdm service nothing really happened. It looked exactly the same way as restarting kdm without performing other two commands.

[Caesar]

Any other ideas?

[oshunluvr]

Whats the output of:

lspci -nnv |grep VGA

[Caesar]

At the moment it displays

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation G84 [GeForce 8600M GT] [10de:0407] (rev a1) (prog-if 00 [VGA controller])

The topic seems dead... :-(

I installed Ubuntu 12.04.1 64-bit and it is affected by the same problem. Does that mean there's something wrong with the drivers? Recently I was re-installing my Windows Vista 32-bit on the same laptop (dual-boot), and newest drivers don't seem to work either. Maybe it is a problem with the drivers indeed. Regardless of the architecture...

[tek_heretik]

I found it pretty rare that the driver itself is the buggy problem but occasionally hardware is released with bugs and some people are unlucky enough to wind up with it, happened to me a few times. I find this out after much Googling. ;-)

[Caesar]

I don't believe hardware is the problem, as it works perfectly on Vista and used to work on previous releases (including Kubuntu) too.

Same here

Hi,

any solution for this problem ?

I've tried with 2 fresh installs on 2 separate laptops, and each time no way to make nvidia drivers work with Kubuntu 13.04 64 bits

On additionnal drivers list, I've got a list of 5 entries exactly the same without any version number "NVIDIA binary Xorg driver, kernel module and VDPAU library", and activating one of them is useless.

On my desktop computer, which I've updating (not a fresh install), it works fine.

On the laptops, with previous versions of Kubuntu, it was ok.

Regards,
