Hello: The Nvidia Driver 313.18 Certificate works perfectly in Ubuntu 12.10-64 bits seems to be some improvement in performance but minimal, based on a series of tasks in Einstein I see an average improvement of 1.7%. see more evidence.

For installation I used the compiled. Deb "launchpad.net" for Driver 313.18 and 313.09-2 Nvidia-Settings after uninstalling the driver above 310.

Nvidia-Settings 313.09-2 I do not see this apparent changes to the previous version, maintains support to "Coolbits 4" (for fan control) for both GPU and if multiple installed. Greetings.

Carlesa - do I correctly understand that you are saying that 313.18 Linux gives manual control over the fan speeds? Is it possible to over clock too?

MJH

Hello: Option Coolbits in Nvidia-Settings is available for a long time, which is not possible to control the fan speed and frequency + cores, "Coolbits 4" is for the fan and "Coolbits 1" for OC, ie one or the other, not both.

What happens is that if we have more than one GPU is not possible to control the fan of each, with Coolbits 4 or 5, you have only one monitor connected, the solution is as I said in another thread, install a virtual monitor Nvidia-Settings deceiving. Greetings.


NOTE: A CanalBoinc mate, told me an easier option to install Driver 313.18

sudo add-apt-repository ppa:otto-kesselgulasch/nvidia-current

sudo apt-get install nvidia-current nvidia-settings

Hello: The commands described work perfectly, I've tested before informing them here, Possibly the error is not indicated to be updated, sorry.

sudo apt-get update

sudo add-apt-repository ppa:otto-kesselgulasch/nvidia-current

sudo apt-get update

sudo apt-get install nvidia-current nvidia-settings

Bear in mind that we start from a (Ubuntu 12.10) that has a mounted above Nvidia driver, whatever.

If you have not previously installed a Nvidia driver and off we're using Nouveau (a newly installed Ubuntu 12.10 for example) will have problems.

The problem is that Ubuntu 12.10 has been released without the package "linux-headers-generic" header containing generic Linux Kernel. This is necessary to install a proprietary driver, Nvidia example.

Previously we must install from a terminal:

sudo apt-get install linux-headers-generic

In principle NOUVEAU uninstall unnecessary, but I've uninstalled prior to mount anything from Nvidia.

Naturally all these things are the responsibility of each and what is best to do first in a test facility or non-critical.

Nobody pays me to do this so it's non-critical, no problem. I'm reinstalling Ubuntu 12.10 now. I had a driver installed and working (it was crunching GPUgrid tasks just fine) before I tried upgrading with the commands you suggested so I don't know what went wrong. I did not install the drivers exactly the way you recommended in your earlier post, I installed some 3rd party driver and maybe that caused the problem, not a big deal, it's all good fun.

This time I will install Ubuntu 12.10 then install the 304.5 driver exactly the way you recommend in other recent posts then I will try the upgrade to 313.18.

Carlesa25,

I have reinstalled Ubuntu 12.10 3 times and have installed the 304.x driver exactly as per your advise in this post. Then I installed the 313.8 driver as per your advice in this thread. It works up to that point and BOINC recognizes the 313.8 driver. Unfortunately when I add the Option "Coolbits" "4" to xorg.conf and reboot it will not boot. I get a message box saying

The system is running in low-graphics mode. Your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself.

I click OK and get a radio-button box with 4 choices

1) Run in low graphics mode for just one session (it hangs if I select this option)
2) Reconfigure graphics (this option gives 3 choices but none of those work)
3) Troubleshoot the error (hangs)
4) Exit to console login (I selected this then removed the Coolbits line from xorg.conf and rebooted but it boots to the first box above)

Three failures... something is wrong. Is the 313.8 driver specifically for a 2 GPU system? I have only 1 GPU. Why does it not like the Coolbits line?

Hello: The 313.18 driver is for any configuration:

The option Coolbits 4 how and where placed in xorg.conf ...?

Without the option you Coolbits system works well ...?

I have tested Coolbits on 313.18 in Screen section and all is ok. (Ubuntu 12.04).

Hello: The 313.18 driver is for any configuration:

The option Coolbits 4 how and where placed in xorg.conf ...?

Like this:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GTX 570"
Option "Coolbits" "4"
EndSection

Without the option you Coolbits system works well ...?

It worked perfect for about 1 week with driver 305.x with Coolbits 4. Then I tried to upgrade to 313.18 and then I got the error I mentioned.

A few minutes ago I installed Ubuntu 12.10 again and it gave that error when I had 3.5.X installed, before I upgraded to 313.18. Weird.

I have tested Coolbits on 313.18 in Screen section and all is ok. (Ubuntu 12.04).

When I was using Kubuntu 11.10 I put the Coolbits in the Screen section. It seems to work either in the Screen or the Device section. And I used Coolbits 5 too for a while and that worked too.

It's gotten worse. It's looking more like hardware failure and less like the fault of the 313.8 drivers or the installation procedure. I'm thinking it's a couple bits "stuck" somewhere in the GTX 570. I've powered the machine off and will let it sit a few hours. When I power it up I'll do a CRC on the install disk then install the nVidia drivers exactly the way that worked and crunched fine for a week. If that fails then it's time to run memtest and friends.

Thanks for the help, all. Would the moderator please hide my post with the big red warning.

Nope. RAM and everything else looks OK. It's all fine until I use the nvidia-settings app to save the xorg.conf file. At that point it asks for my password because it says it needs root permission to alter the video settings. Then I reboot and it refuses to boot and instead I get the message about "The system is running in low-graphics mode..." as I explained earlier. If I drop down to a shell prompt and view the X logs it mentions inconsistencies in xorg.conf, missing Screen section and what not. That's where the problem is... xorg.conf. OK, now to find the fix. I bet if I edit and correct the xorg.conf after I save it from nvidia-settings it will work. Trouble is I don't know exactly what xorg.conf should contain. To get a working xorg.conf I need to install the drivers the scammyhash way I used before Carles25 told me the proper way. For some reason that method gives a proper xorg.conf whereas Carlesa25's method does not. So the plan is install the wrong way to get the right xorg.conf then install the right way to get the wrong xorg.conf then fix the xorg.conf, then install the 313.18 upgrade. No wonder I don't get paid for this, nobody with money would believe me if I told them what I have to do to make this stuff work sometimes.
