Does the following command produce an error? Or does it look like it works by advancing to another line, giving you a prompt and waiting for another command?

# apt-get --purge remove xserver-xorg-video-nouveau


The result of the command:
# apt-get --purge remove xserver-xorg-video-nouveau Reading package lists... Done Building dependency tree Reading state information... Done Package xserver-xorg-video-nouveau is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.


Does the following file exist? /etc/X11/xorg.conf

No, I checked! No file!


Seems every where I look, the nvidia driver needs X to work. I could be wrong though.
Everything I google on this subject keeps me thinking you need X loaded on your server to get an Nvidia card crunching correctly for boinc/sah. I could be wrong though.
I really can't find any other suggestions for you.

Well, now we are getting somewhere! Please explain the difference between X-server and "nouveau".
I've been reading about repository, and PPA (Personal Package Archives), and drivers current, and etc. etc. I'm more confused know, than when I started reading 14 days ago. This, I think, I never will understand. And I'm very sorry about that!

I wish I could learn how it works, I really do...

So thanks you, thank you both!

mc is midnight commander

if you use norton commander under DOS, or FAR commander on win, you must familiar with that tool.
just do "mc" from console, and if that package is installed, you see.

about ubuntu - i do not familiar with that distro. i mainly sit on slackware ( one of oldest and simplest linux distro).
on my experience, nvidia, after driver installation ( from nvidia.com site) work well with nvidia cards, and boinc see it and works.
nouveau is free driver for nvidia - i think it is from two parts - first - kernel module, who loads with kernel, and second, additional driver, who loads with x server.
if you not x server running ( you can check this by "ps ax" command from console, or try switch to terminal 7 or 8 - ctrl+alt+ f7 or f8 - there must be a x window manager, if any is running.
with command "lsmod" you also can see loaded modules list.
i may suggest you to install slackware on one machine \ hdd - that is a much more logical and easy distro, end even if you have problem on that, i can help you more efficient with slack, who i know less or more...

i have a machine with gf210 at work, under slackware64 - it run at runlevel 3, without x server running, and boinc see that card, and use it for tasks computations.
that is one of fact, who i have.

Guy,

And reading the release notes for Nvidia 331.38, the notes say there is added support for xorg-server and a bug fix that causes X-server to crash if video memory is exhausted and the GPU does not support rendering to system memory--hence my continued assertion that you probably need X in order for your Nvidia card to crunch SAH data.


OK, if I make a clean installation of Ubuntu Server 12.04.4, then X is NOT installed I guess!?!?
I need X to crunch!? But, I got it to run, but only for a few hours. I made another post about that. Maybe it didn't crunch anyting, I don't know for sure, but it seems to begin and then after a few hours, it freezes.
Look here: http://setiathome.berkeley.edu/forum_thread.php?id=74040#1476035

X is a graphical interface, thanks. Well, maybe a clean installation of Ubuntu Server 12.04 and then install X, and then "kill" the nouveau thing... Like in my todo.. I'll try that, when I heard your reply. I'll look at the links you showed me now ;)
Thanks for all the help my friend ;)


Hi Draco,

mc is midnight commander
if you use norton commander under DOS, or FAR commander on win, you must familiar with that tool.
just do "mc" from console, and if that package is installed, you see.

OK I see.. I will take a look on MC because I used Norton Commander when I was a boy! Back in the old DOS days ;) What a beautiful beautiful time ;) Norton, with the blue screen and nice HDD tools ;) I loved it, had to "play" every day ;) Thank you for taking me down memory lane ;)

i have a machine with gf210 at work, under slackware64 - it run at runlevel 3, without x server running, and boinc see that card, and use it for tasks computations. that is one of fact, who i have.

Well, I'll like to stay with one OS. I started out a couple of yeas ago with red hat, then SUSE Linux.. After some time we agreed on Ubuntu. And since I don't understand it, as you can see with the problems I have with this GPU/Nvidia stuff, I think it's best for me to stick with Ubuntu. But I will remember what you told me! And I will read about it, that's for sure. I just think it's best for me, in the middle of all this, not to change. But thanks anyway!!! I appreciate your help!

Run levels, I'm not sure how it works with Ubuntu Server. I know I can access tty2, but I don't know how it works compared to Desktop environments. Many of the "helping posts/todo's" on the web for Ubuntu 12.04 is for Ubuntu Desktop and not for the Server Edition. That's why I get more confused when I read all these sites. But with help from you guys, I'm getting there ;) Slowly, but surely ;)

http://www.linuxquestions.org/questions/ubuntu-63/

linuxquestions is great resource, i think, you can try ask questions about ubunta there - there is a special ubunta users forums.

i do not know, what way ubunta is organized, and no will investigation in that distro. some times i get in touch with redhat, centos,mandriva / mandrake, and debian. i decide to stay with slackware, because, when you try to get in "low level works" on that distros ( like a startlevels and so), there be an unnecessary complicated things there. in slack all there was clear and good.
initlevels is level, in what system work. initlevel 1 is single user, level 3 is multiuser, and level 4 or 5 is graphical.
in slackware it regulate in /etc/inittab ,and can be switched between from console via commant "telinit Y" where Y is runlevel number.


tty2 is console number. you can switch between this, if you in runlevel 3 or 4 (5) and is on local machine ( with keyboard) with pressing ctrl-alt-F1 to F7
f1 is first - tty1, F2- second - tty2, and sio on. F7 / F8 switch you to X window manager, if any running.
i suppose, it is good to ypou to purchase some books about how linux works, and read them...

Hi Draco,
In Ubuntu Server you boot into shell mode right from start-up. Isn't this already tty1? Well, I'll work with it, and try some things, but I could not find a answer on how you leave tty again. I did it once, but forgot about it. I do have 512 post-it's on my screen with great and usable commands, but this I don't have. So, how do you exit ttyx?

Thanks for the links, by the way!

F7/F8 to switch into X, OK, but this we are still discussing. If I need to install X to make the GPU crunch data with Nvidia graphic card.

Dan, X-server is X. X is from x.org. X is the graphical interface. X is the linux windows.

Nouveau is an attempt to reverse engineer Nvidia drivers so there exists an open source form of the Nvidia driver.

And reading the release notes for Nvidia 331.38, the notes say there is added support for xorg-server and a bug fix that causes X-server to crash if video memory is exhausted and the GPU does not support rendering to system memory--hence my continued assertion that you probably need X in order for your Nvidia card to crunch SAH data.

http://www.geforce.com/drivers/results/72250

But since you are trying to figure out how to get it to crunch with out the desktop interface, all I can do is wish you good luck because I'm out of ideas.


Hi Guy, I'm all ears ;) And now I reinstall the server with a clean installation of Ubuntu Server 12.04.4 64bit, and then I will find the right way to install X on Ubuntu Server 12.04.4, then I will install the 64bit driver with X bug-fixes and see what happens ;) I think it's the right driver you showed me! http://www.geforce.com/drivers/results/72250
Congratulations with the most exciting hockey match in the last 20 years! Great performance by the Russians though! What a will they had! I'm not sure about the 3-2 goal (the one where the goal was moved 1 inch) was judged correctly, but never the less, it was the match of all times! So congrats...

Hi Guy,


I got this far. Wipe computer, reinstall Ubuntu Server 12.04.4 64bit, install X, and the the Nvidia 64bit driver we choosed, but!

To install X, I got this far:

Remove existing xorg using the following command: # apt-get remove --purge xserver-xorg Install xorg using the following command: # apt-get install xserver-xorg Reconfigure xorg using the following command # dpkg-reconfigure xserver-xorg


What needs to be reconfigured before installing X. I think of this "dpkg-reconfigure xserver-xorg"???

And, I don't want to boot into GUI (Yes I learned a new word ;)

Do I need to install GCC still? And what is GCC??? I studied for several hours, reading:
http://gcc.gnu.org/gcc-4.6/changes.html
https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/UbuntuServer

It's just a great mystery to me, why it's necessary to install a graphical interface in a non-graphical environment, to make data crunching possible!?!?
Please take a look at these warnings:

what, you think, is a point to "exit ttyX"? who that "exit" give to you?


>If I need to install X to make the GPU crunch data with Nvidia graphic card.

i be pretty sure, you do not need any X for crunching data via nvidia's GPU.

Hi Draco,

Well, some are against it and some are for. I have to try it all to find a way. I studied more than 500-600 sites, containing these issues, ubuntu server gpu boinc, ubuntu x gpu, ubuntu server 12.04 nvidia gpu boinc etc. etc. I'va come close a few times, but no cigars!

I've invited the best brains from inhere to join in, a solve this matter. Why, because I found out, that I'm not the only one interested in building servers for crunching data on the behalf of some kind of organisation.

You got some pretty interesting suggestions as well, so please join in. I will keep out of the discussion as much as possible, to let you BOINC guru's do all the work. Just kidding, no, I will keep out of it, because I think maybe I make it a lot worse clowning around o)

Please join in:
http://setiathome.berkeley.edu/forum_thread.php?id=74108#1478001

Right now, I am reinstalling ubuntu server 12.04.4, to follow another todo I made, which include exactly the X-server vi talked about.


Guy quotes Draco:

Draco says, "i have a machine with gf210 at work, under slackware64 - it run at runlevel 3, without x server running, and boinc see that card, and use it for tasks computations. that is one of fact, who i have."


Hi Guy,
Yes, I get that, but right now there's no better solution. I actually doing the reinstallation right now and I will try the X to see if it works..

And here's a quote from one of the "better solutions" of the post I made:
Minimal GUI: To get BOINC to recognize that you have a GPU, BOINC has to be loaded AFTER some sort of graphical user interface (GUI) is up and running. For this, I used a simple display manager:


Could it be that changing to BASH would help?
Could it be that Disabling AppArmor would help?

As I told Draco, I invite you guru's to join in, and get this solved. Please join in, I saw many of your posts, searching the web this weekend, for solutions regarding BOINC/GPU etc.
Please join in:

Sorry Dan, i do not join in.
there is already distro, who work with seti good in all aspects almost out of the box.
if you want to fck and struggle with distro, who, looks like big problems to get seti with GPU working - it's your choice. i do not want waste my time.
also about "i reading tonns of information about linux and seti" - i think, for first, you must learn the linux basics - how its made. how itš work and so on. it is very different things and philosophy, than MS products.
it is no wise to try repair car engine with electronic injection, if you do not know anything about it principes and so, only based on "i read tons of advices in internet!".
thats my opinion.

Hi Draco,

You are right. It's stupid, I know. But like you, I don't want to change again, because, then I'll be the same place as I am now, in a year from now. I hope you can see my reasons. I'm so close, to ask you for the version you use, and just get on with it. But as you say yourself, I need to learn. and you don't learn by quitting halfway through, and choose the OS because it works with e.g. boinc. But, maybe I should just install the graphical version and then be done with it, I don't know. I just don't like to quit. Ubuntu is very very good in other places, where I had trouble before. Webservers, Mailservers, DNS etc. works great!
But, I will keep all your advice in mind, you can be sure of that! And maybe, just maybe, if I give in, I'll shout out for you again - hoping you'll show me just the way you did it ;)

Thanks a lot for all you help!

Dan...

i think, learn new direction is a way better with more simple things - i e better is learn how to works gearbox is better to start on old, mechanic gearbox, than new robotronic 17-speed box.

in any way, i only can repeat - slackware is one of first linux distro, it is simple, powerful,configurable and stable. there no "server", "noserver", and "superserver for users who think a more cool words do it more cool " versions - there is one version for platform, who you can configure as you want - as server, as desktop, etc.
i also use slackware ar dns, ftp,web, mail, fileserver, and firewall for years, and in general not have big problems with all this. i also use slackware on my desktops and netbooks for about 7+ years without big problems. in last month, i also set up boinc to use ati and nvidia GPU almost without problems ( except for ati, but there is ati sucking drivers and so on - you have that problems on all linuxes, it is no distro-induced).
as so, as i said, i prefer to use linux, because i get enought fcking with computers at work - in home i want to some peace of this. and slackware do it for me - once you install and configure it, it works without problems for years.

but, in any way, choice is yours.
i only can advice you to use a right things...

Hi Draco,

I completely agree with you. I'm trying a graphical version and if this don't work Ill try the distro linux. I just hate to give in.
I too don't want trouble with computers, my own that is. That's why I changed from windows to Linux. And then you don't need to buy a larger computer every 6 months like you do with Microsoft..

Hello friends ;)


Almost solved. Wrong edition, right result!

New attempt to solve the issue "Ubuntu Server 12.04.4 64bit - BOINC using GPU - Nvidia driver/GeForce GT610"

Just finishing the clean installation of Ubuntu Desktop 12.04.4 (Desktop, not Server!) Not being able to install the file from BOINC's download site, I did this instead "apt-get install boinc-client boinc-manager" which is showed on BOINC helping pages. But this does not install the newest boinc version. And now a notice tells me to download and install the new version.... etc. etc. never mind that right now.

But, after installing this desktop version, and installing boinc-client and boing-manager, and attaching to project using the manager, I checked to see if the GPU was running. Not yet, so I went on DL the newest driver from Nvidia 64bit 331.38. and making it bootable "chmod +x filename.run". Running the file gave me the same problems as when doing this on the Ubuntu Server Edition! So I went on, doing the same as I did there, almost.
I started a terminal, ctrl-alt-f2 and logged in, the claiming sudo rights "sudo su", then "stop lightdm", then running the Nvidia installer "sh NVIDIA-Linux-x86_64-331.38.run". Some questions are asked during the installation, I answered "Yes" to [install 32bit libraries etc.], "Yes" to [reconfigure X-server or something like that] (I will make a better todo when this is all finished!!)
Rebooting the system and updating the project from Boinc Manager showed me a 5 running unit. (CPU i5-3470 has 4 cores) and this 5 unit is named: (0.01 CPUs + 1 NVIDIA GPU). This I also found when doing it with Ubuntu Server 12.04.4, but the GPU ran for 7 minutes and the the temp. of the GPU suddenly dropped. This meaning the crunching also stopped. But not with the Ubuntu Desktop 12.04.4, here the GPU has been running now for 47 minutes and the GPU is still 47 degrees Celsius!
Here's the log file from Boinc Manager and a screen-dump of Boinc Manager showing the GPU crunching still after more than 10 minutes.:

OK, I couldn't upload a screendump, it's not possible in this forum. The reason I would like to show you this screendump is because when 4 work units were done after about 50 minutes, the GPU had only completed about 5-6% of it's work unit.
I know this card GT610 is a "not very fast" card. We discussed this inhere. But I also learned that GPU's would be much faster doing data crunching that ordinary CPU's !! I will replace the GT610 with the faster Asus GeForce GT640 which I was told would be a much better choice. But how much better will it be?

What is the reason for doing all this work, if GPU's are so much "slower" than an ordinary Intel i5 CPU? How fast is a "fast" graphic card" compared to e.g. i5-3470?

We now know that the hardware in this test works, and we know that it runs on Ubuntu Desktop 12,04.4. OK, then why will it not run on Ubuntu Server 12.04.4? The only difference is the graphical environment, X-server! According to Ubuntu, there's not the difference of the Desktop Edition and the Server Edition as earlier on, e.g. Ubuntu Server 10.04 v. Ubuntu Desktop 10.04!
So why is this? Why will the GPU not work properly?

Any suggestions will be greatly appreciated at this thread:

I'm trying a graphical version and if this don't work I'll try the distro Linux.

Days ago you asked "what is distro?" (for me it seems you still don't know)
"distro" means 'Distribution' or 'kind'/'brand' of Linux

Top Ten Distributions:
http://distrowatch.com/dwres.php?resource=major

You'll see "Slackware Linux 14.1" almost at the bottom of page
http://distrowatch.com/table.php?distribution=slackware


(and I remind you again: I have NO experience with Linux except about for one month ~10 years ago with KNOPPIX (bootable CD)
http://distrowatch.com/table.php?distribution=knoppix
)

Hi Draco,

I completely agree with you. I'm trying a graphical version and if this don't work Ill try the distro linux. I just hate to give in.

OK, I was tired... What I meant to say was Slackware, not Distro... I've been reading about Linux from the start, the first "distro's" etc. Right from where a guy from a university in finland get's an idea up till present time. So I know what distro is ;) If I didn't, I do now ;)

But, what about my questions? Any suggestions?

Hello crunchers ;)


It's here. The new hardware for the next Headless Linux Boinc Server:



Intel i5-3470K
Industrial 2U Cooler from Dynatron or JAC
Industrial 2U PSU ATX300W
Asus P8H77-M Pro
8Gb Kingston HyperX Genesis X2 Grey S.
Asus GT640-1GD5-L PCIe 2.0 x16
Asus GT640-1GD3-L PCIe 3.0 x16


Here's the problem, the same as last time. The brackets for the 2U industrial cooler doesn't fit. Well, back to workshop ;)

http://www.overclock.net/content/type/61/id/1916758/width/500/height/1000/flags/LL
http://www.overclock.net/content/type/61/id/1916761/width/500/height/1000/flags/LL

Problem solved. I've posted a thread around the forums' where people are interested in this headless cruncher. 2 other places where some has joined in and is helping solving the issues. We got one "trick" which will be the first I try. To install the parts of the GUI that makes the GPU crunch, but all using CLI !! That's what we are trying to do!

I bought 2 x Asus GT640 PCIe 2.0 x16 so that we can compare the results of the test Server 1 against this new test Server 2. Server 1 or cruncher 1, has a Desktop Edition installed where this Server 2 will be all CLI. Then after we have made it work I will compare the two system. To see if it really matters. If Server 1 with GUI really is slower, much slower.

If anybody knows how to install the parts of X which the GPU uses to crunch, please don't hesitate to tell me.
