12.04 broke nvclock?

[d4m1r]

Hey guys, did anyone else running 12.04 manage to get nvclock working because I can't I tried installing it through the software centre, and by installing both the 32 bit and 64 bit .deb's available on nvclock's official launchpad, but I always get the same result:

damir@damir-ubuntu:~$ nvclock -f -F 80
Segmentation fault (core dumped)

I have a GTX 260 so currently it is running on stock fan speed which is low, and I use nvclock to set it higher (login script). Yes I know I can get temperature values from the official Nvidia application, but I am trying to set fan speed, not read the temperate....Anyone have any ideas?

Is nobody else using nvclock Is anyone able to set their Nvidia GPU's fan speed manually using something else under 12.04?

I use nvclock for screen backlight control on my Sony Vaio VGN-NR31S.
I have the same errors you got: they started when (in ubuntu 11.10) the nvidia drivers updated to the latest version 295.40 (on 11-04-2012).
Now, in ubuntu 12.04 (with the same drivers) I have the same problems.

Does anyone know what is wrong whith nvclock?

Thank you!

Same problem here.

Not sure why it's broken but it just is....

See THIS thread I created for an alternative way to gain control of your Nvidia GPU's fan that works for me in 12.04.

Unfortunately this doesn't solve my problem.
I NEED to use nvclock, because there is no other way to get the control of the backlight with my GPU.
Any news about it?
Thanks!

nvclock is broken due to recent drivers, you can just use nvidia-settings as nvclock. To set the GPU fan speed just issued these

nvidia-settings -a [gpu:0]/GPUFanControlState=1

That enables modifying the Fan speed

nvidia-settings -a [fan:0]/GPUCurrentFanSpeed=100

Set's the speed.

nvidia-settings -e list

for all the settings, replace list for all for it to tell what does what

Remember to set coolbits to 5.

For Brightness, you might want TVBrightness or just Brightness

Thank you very much Lisiano for the suggestion.
My problem is that I can't use nvidia-settings as nvclock, because I was using a modified version of nvclock that let me change the brightness (I have one of those Sony Vaio in which the brightness can't be changed with "traditional" commands)!

Any ideas?
Thanks!

Not sure but could you try echoing this?

echo "0" | sudo tee /sys/class/backlight/acpi_video0/brightness

Replace 0 with any number from 0 to 7. Think that should change the backlight without using the Fn keys.

EDIT: I don't own nor seen a laptop that won't change it's brightness. I did see a VAIO once but it did change brightness, even in Ubuntu.

Thank you for helping, but I think my problem is a little bit more complex.
My problem is quite usual for a series of notebook with nvidia graphic card.
A bug was open in launchpad (https://bugs.launchpad.net/ubuntu/+s...tup/+bug/95444) and a solution was found: through a modified version of nvclock you can have the backlight control.
The problem actually is that whit the new nvidia drivers nvclock doesn't work!!

So, this is the problem!

I even tried to install the old nvidia drivers versions (through .run installers), but I didn't manage to complete the installation!

Any help will be useful!
Thanks!
