I installed the new beta driver (317.12)

Option "Coolbits" "8" enables overclocking
Option "Coolbits" "12" enables overclocking and manual fan control

Execute the command below add "Coolbits" "12" to your xorg.conf file.

sudo nvidia-xconfig --cool-bits=12


It all seems to work for my 780Ti.

Hello: I do not work (it is actually 337.12) this driver, BOINC does not recognize my GPU (GTX770) on my Ubuntu 14.04 64bit Kernel-LowLatency.

Can you confirm if it works well on your system?.

Sorry about the typo. The Driver version is 337.17.

Boinc recognizes my 780Ti and has finished 2 WUs with the new driver. I've tried reducing the graphics clock offset and it does work.

My OS is linux Mint cinnamon 16 (64-bit)

I'll try my other systems this weekend (GTX570 and GTX660Ti).

The beta driver 337.12 also works another computer with the same OS but different GPU (660Ti). At any rate, it's nice to be able to overclock/underclock my graphics cards in linux.

Is there any way to edit my first post and title to change my error in driver version number?

Not sure where you got the 337.12 Beta from? The main Beta is the 337.50 version, released on the 7th Apr '14.

Might try it over the weekend...

I was running nvidia-331.49 on an Optimus notebook without any problem. I've just updated the drivers and couldn't get Boinc run with any of 331.67, 334 and 337 drivers. Maybe it would run it as main GPU but couldn't get it run with Bumblebee.
I reverted to the older 331.20 driver and it's running a GIANNI WU with %100 usage of one hyper threaded CPU core. I don't know whether it is sth. with the workunit or driver.

Hello: In UBUNTU 14.04-64 bits totally clean, reinstalled, all NVIDIA Drivers 331.49 post are not recognized by BOINC, works but no GPUs. available.

So far I have had to return to the Nvidia 331.38 or 331.49 versions that work perfectly in both Ubuntu and Boinc.

Yeah, I see that now. Maybe their search facility reset my OS back to W7 because I was working from a W7 system, or their .uk site wasn't quite right.
Title fixed.

Hi, For the moment Ubuntu 14.04-64 bits Trusty has a problem with BOINC.

I review again and reinstalled several times with different drivers and do not work 331.67, 334.21, 337.12. I've also tried several Kernels without result, not missing, I guess some library ...??

Which works perfectly on BOINC+Trusty is 331.49 even 331.38 GPUGRID works but gives errors.

I was able to get the 337.12 driver installed on my mint 13 LTS system with the GTX570 but it wasn't trivial. After installation, the screen would freeze with multicolor horizontal lines during the boot process. I discovered a discovered a solution by accident though. If I booted during recovery mode, I could make it to the menu which has a number of options. If I choose "resume normal boot", then it would boot into the desktop with a function driver. It's a bit cumbersome but since I rarely reboot the computer it's something I can live with.

Nvidia-settings shows the options for manual fan control and overclocking options and GPUGrid is running without errors so far.

Those recently updated drivers have some problems with CUDA or something else. I tested all of them in Kubuntu 13.10 and couldn't get the works started anyway. Log says Nvidia drivers present but no GPU's found.
I wanted to revert to older 331.49 driver but it is removed from the repo and I don't have its deb file. Repo has 331.20 and it is running the works but with one virtual core of the CPU %100 utilized.

Bumblebee bad!

Hello: Well ... in the end I managed to install the 337.12 also running BOINC and Option "Coolbits" "12" enables overclocking and manual fan control.

The only way that has worked has been a manual installation and in the process indicate that the NO Driver Nvidia Kernel register, the rest of the options during installation (included install 32bit libraries) must be accepted.

So far it works well and I've completed a task successfully GPUGRID Short.

I found a 331.38 driver, now Boinc can use the GPU and with no extreme CPU load. I think the problem is not with Bumblebee only.

I read problems with 14.04 beta versions, but LS version is out now. Now, I downloaded 14.04 and after a long time taking backup I will try it. :)

Now, I'm running Kubuntu 14.04 and most of the things running perfect. When installing bumblebee it installed nvidia-331-updates which is nvidia-331.38 by default. I even didn't add the edgars repositories.
Now Boinc is able to detect CUDA and OpenCL
I tried updating but couldn't succeed due to sth. nvidia-persistenced... Tried formatting and had no problems during the installation and after except a single thing.
My integrated graphics seem to have some problem now. It runs glxgears etc. but can't find libgl in boinc and have some display quality issues.

Hello: The final version of Ubuntu 14.04 LTS install the Nvidia Driver 331.67 and the result is that BOINC is not GPUs.

Currently the only solution is still manually install the driver. During installation no Registering the NVIDIA Kernel Module with DKMS so that everything works properly.

I trust that as the problem is detected by all BOINC users UBUNTU the issue is resolved.

I installed Bumblebee and it installed 331.38 driver which is the driver I used in 13.10 after breaking it with 331.67. In fact that is an old driver, 331.49 was running fine but I couldn't find it after updating to 331.67.

Try installing 331.38 and I think it should run. It is in the software center.

After messing up two stable Ubuntu rigs (13.04 and 13.10 which used 331.49 and did work with CUDA6 at least at one time) trying to manually install drivers, I eventually managed to upgrade one system to 14.04.
Unfortunately the only drivers available via repositories either don't work with CUDA6 or the Boinc Client can't see the GPU's!

I tried coolbits, sudo nvidia-xconfig --cool-bits=12, and it does let you change the fan speed of the first card (but not the second). Not that it's any use when Boinc can't see the GPU's. Didn't see any option to change frequencies (OC/DC).

I finally stumbled upon a sequence of commands to get the 337.12 beta drivers installed in Ubuntu 14.04. So far they are working fine with BOINC 7.2.42 from Berkeley.

Uninstall any proprietary drivers that you have installed now.

Download the Nvidia driver

Create a file in your home directory to blacklist Nouveau drivers
Use gedit to create a file named blacklist-nouveau.conf
Add the following lines to blacklist-nouveau.conf

Hi: Thanks - captainjack - for the information, put into practice in the next round of tests.

For my part I have working perfectly BOINC Nvidia 337.12 and 331.67 on my two Ubuntu 14.04 machines (with different Kernels) but with the difference that I have NOT registered with DKMS during installation.

Anyway both its solution as mine no longer an interim patch.

You can not be a normal user perdir entering this trouble, it is unfortunate, Nvidia and Ubuntu-Canonical have to give any definitive soilución.

Thanks for the instructions captainjack.

It seems it's always a hassle to install the latest Nvidia drivers on linux.

There are some useful tidbits in the nvidia README file.

http://us.download.nvidia.com/XFree86/Linux-x86_64/331.67/README/index.html

Hey skgiven,

Glad to hear that the install instructions worked for you. That makes two of us that have used them successfully.

Couple of follow up comments.

When I issue the "sudo sh NVIDIA-Linux...." command I have to use the full file name also. I left the .... in there in case anyone else wants to use a different driver version. I've read that a person can issue the command "sudo sh NVIDIA*" and it will run whatever it finds that starts with NVIDIA. That's probably ok if there is only one NVIDIA driver in the Downloads folder.

I looked through your other comments and they all look appropriate.

Thanks for the feedback and updated instructions. Hopefully they are clear enough that other people can follow.

Hello: At the moment -captainjack- following in their footsteps, not the NVIDIA driver achievement was recorded in the Kernel with DKMS, possibly due to the use KernelLowLatency 3.14.1.031.401 uy that certainly works well and fast.

Anyway it's a minor problem because it all work perfectly, NVIDIA 337.12 including BOINC.

Note: Personally I would recommend using the 331.67 driver before the 337.12 since this is a Beta and its operation is not all good.

The problem here is that 331.67 fails CUDA6 WU's.

Is Nvidia driver 331.67 working with CUDA 6 tasks on Linux?

Thanks Jim

Now that summer is upon us, I needed to speed up the fan a bit. I tried the command that biodoc recommended in the first post

Now that summer is upon us, I needed to speed up the fan a bit. I tried the command that biodoc recommended in the first post

sudo nvidia-xconfig --cool-bits=12

and that didn't work for me. I had to manually edit the /etc/X11/xorg.conf file and insert a line for coolbits at the following location:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "Coolbits" "12"
EndSection

Now I am able to control fan speed with the Nvidia X Server Settings software.

anyone have fan control working on more than one card with these drivers?

Next challenge:

I finally stepped up and bought a motherboard that would support 3 GPU's. It currently has a GTX660ti and a GTX770 installed. There is a monitor attached to each GPU. It is running Ubuntu 14.04 and BOINC 7.2.42. I was able to get the 337.12 drivers installed and get it set up with coolbits enabled so I can control the fan speeds on each GPU.

Now I want to get the second monitor that is attached to GPU #2 to actually work. In NVIDIA X Server Settings is an option for Xinerama. With that option turned off, the screen on the second monitor is black. When I move the mouse to that screen, it shows up as a black X outlined in white.

When I turn the Xinerama option on, the second monitor shows the background and the menu bar down the left side of the screen. I can move a window from the first screen to the second screen or I can select a menu option from the second screen and open up that window on the second screen. But here is the bizarre part: When I open up a new window on either monitor, all other open windows on both monitors go black. For example, I can open up BOINC Manager and see it just fine. If I leave it open and then open up a Firefox window, the BOINC Manager window goes black. If I then open up a terminal session, both the BOINC Manager and Firefox windows are black and the terminal session can be seen. I can "grab" the bar at the top of a black window and move it around but it is still black. However, if I grab the edge of a black window and resize the window, all of the contents of the window will show up and whatever else was active goes black.

Does any body know what settings to tweak to make both monitors work and be able to see all open windows all the time?

Thanks for all the help,
captainjack

Ubuntu Unity is based on Compiz and compiz has never worked completely OK with multiple monitors. Ubuntu does make it significantly more stable and robust to work with multiple monitors, but it cannot cover every possible setup. You're using two GPUs, if you had your monitors on a single GPU, things would be much better.

I think your best bet is to use another desktop environment than Unity (Ubuntu's default), one that does not depend on Compiz. You can try something like XFCE or MATE.
