Hello.
In one of my PCs with Nvidia Quado NVS295 graphic card there's Linux Ubuntu 14.04 - Gnome Desktop, kernel 3.13.0-39. The Nvidia driver is 331.78, downloaded from the Nvidia site. Boinc doesn't detect the lack of user activity. SETI@home should work on both CPU and GPU. It seems that everything is ok, GPU is detectable, the Astropulse suite for GPU is downloaded, but my PC doesn't process it. All suites for CPU are normally processed, but nothing happens for GPU. It says 'GPU suspended - PC is in use'. After 5 mins the screensaver turns on but the GPU processing does not start. After 60 minutes and moving the mouse my desktop shows normally, but when I check the Boinc Manager, there's no progress in GPU processing.
My PC doesn't turn off there, it doesn't go into the state of dormancy - it's working all the time, only the screensaver turns on. The GPU processing can be turned on manually after pressing 'always use graphics card', Boinc just doesn't detect the lack of activity.
I've already read
http://setiathome.berkeley.edu/cuda.php and
http://setiathome.berkeley.edu/cuda_faq.php and everything seems to be as it should.
It's like it doesn't see itself not working.
Does anyone know how to fix it?

Can you post the first 30 lines of your advance event after restart. I'm going to let the others take a shot at this.

In BOINC Manager, under Activity, do you have "Run Always" and "Use GPU Always" selected?

---

This is a known problem with Boinc on Linux, it works on some distros and not others,
You don't say what version of Boinc you're using, And with your computers hidden we can't find that out.
and where you got Boinc from, from Berkeley, or from the repository?

Claggy

Do you mean these? I'm using Boinc 7.2.42 delivered from distro.

It would help if you unhide your computers so we can see what task were downloaded to them. No personal information is shared by the server, it only allows us to see the computer and what OS and task there are.


Zalster

I've hidden my computers so long ago, that I can't seem to find the option to unhide them now. I think I may have done it, my preferences say they're visible, but I can't see them myself.

---

Still hidden

Should SETI@home show your computers on its web site? "Yes"

---

click on Your Account at the top of the page, the click on SETI@Home preferences, it's the 7th item down. To edit that page scroll to the bottom and click on Edit SETI@Home Preferences change to Yes then save.

Edit..

After you do that, update your the project from the boinc manager

Thanks Mike

The host needs to contact the servers first until changes take effect.

---

With each crime and every kindness we birth our future.

I've checked it half an hour ago and contacted each of my computers with the project server three times now, but nothing happened so far.

SETI@Home Preferences -> Primary (default) preferences -> Should SETI@home show your computers on its web site? -> YES

---

are all your computers set to default? I have some at different location profiles. I make sure all my profiles allow the computers to be seen.

It's possible that we're waiting for the server now. In my account info it shows 1 post, but I've written 5 already. So maybe it's server delay.

Edit:
It's already showing.

I've installed a driver from the Nvidia site, that's suitable for my graphics card v 340.46. Nothing has changed. The setting in Boinc Manager "always use graphics card" works, but if I try to turn it on on a pc that's working for some time already, the GPU processing does start, but it immediately stops working and a window pops out with "waiting for start up..." although there's not a single app working at that time other than Gnome. After restarting my pc, when I toggle "always use graphics card" on it works without problems. The problem is, that option can't always be on, because the pc in unusable. The graphics card works with a massive delay.
Do you know how to fix this?

I don't think you can do anything to fix Boinc 7.2.42 for your distro (any Boinc updates available?), you could upgrade to your OS, that'll give you a later package:

https://launchpad.net/ubuntu/+source/boinc

You could also email the Debian BOINC Maintainers and report the problem, maybe they'll be able to backport a later version down to Ubuntu 14.04

Your NVS 295 is based on the G98 (pre-Fermi) core and drivers based on 340.xx (and newer versions) break the OpenCL capability of older cards (see this thread for more details).

Downgrade your driver to an earlier version to correct the problem.

Cheers.

There's no update available for my distro. Boinc v 7.2.42 i official on the Boinc website. The higher-numbered versions are all developmental and they can contain many bugs - I don't want to use them since I'm not a programist.
I'll try using online help. I'll see what can be done.
I there's still nothing by then, I'll just wait for the next version, it should be coming out soon.

I'm aware of that, but it's worth giving a try ;) On Windows 8.1 a message window popped out about it in Boinc Manager. On Linux still nothing - the message was "waiting for start-up". At the moment, I've got the driver in v. 304.117, that's available in distro - of course nothing has changed, that means if I turn on "always run" manually it works, but if I choose in options that the GPU processing should start after, for example, 2 minutes of inactivity, nothing happens. The GPU processing doesn't start even after an hour.

I was wondering if there an option exists, that needs to be added when starting Boinc. That led me to writing my question on this forum.

They can... but there was one time when the outdated BOINC version published in the official repositories had a bug which killed all processing, at least for S@h. I had to use costa's BOINC PPA as a work-around and have been using it ever since then - it's actively maintained and only one time there was a problem. He fixed the issue within hours of my query about it.

Up to you as to whether you want to give it a try but it's an option at least. If it doesn't work out you can always remove the PPA from your sources.list and revert to the version from the official repository.

Soli Deo Gloria

Have found something @ boinc-dev board:
http://boinc.berkeley.edu/dev/forum_thread.php?id=8161

in short:

Else try in a terminal window, for each BOINC session, "xhost local:boinc"

as far as i know on windows, a "boinctray.exe" is used for idle-detection. this can't work on linux, so i assume that this is done through some x-window functions which first must be granted with above command?
