After changing the motherboard and setting up everything (OS, NVIDIA drivers, BOINC, SETI, nvidia-modprobe) from scratch again, BOINC/SETI uses only the CPU and does not offer GPU-Tasks. With the old MB and one Graphic Card all ran perfectly.

In SETI@home preferences 'Use CPU', 'Use ATI GPU', 'Use NVIDIA GPU', 'Use Intel GPU' are all marked (default - no changes).

Since I plan to add more 5 GPUs to this MB, at least the first one should work...

Any help?

FYI, this is the event log after starting BOINC/SETI:

Hi,

I see a line saying "Mon 19 Jun 2017 07:54:21 AM CEST | | don't use GPU while active"
That can be set in BOINC manager GUI computing preferences to allow GPU computing all times not just when computer is idle..

Thanks,

I unmarked in the GUI 'Suspend GPU-Computing when Computer is in use.'.
The number of minutes in 'in use means mouse/keyboard input in the last ... minutes' , which was before 0.05 is now greyed out.

And just to test some more possibilities, I unmarked in Your account- Seti@home preferences the marks at 'Use ATI GPU' (no ATI GPU installed) and 'Use Intel GPU' (as another test).

In short: still no GPU tasks offered...
Problem not solved.

And the last lines of the event log concerning new tasks are:

This is another try to use Linux. It seems I have to use Windows as on another PC, where multi GPU-crunching works without problems.

So if you exit & restart BOINC Mon 19 Jun 2017 07:54:21 AM CEST | | don't use GPU while active is no longer in the startup messages, as it appears to have been set on that computer.

Take a careful look at you app_info file.
You may have a missing tag causing it to ignore the GPU section.

Correct.
No longer 'don't use GPU while active'

@Brent Norman
When I used the last time LinuxMint18.1 with only one GPU on another Motherboard, I did not have to look at app_info.xml or app_config.xml or to change one of these files. CPU and GPU ran perfectly.
I now have 3 GPUs connected to the new motherboard, BOINC recognizes all of them (CUDA and OpenGL). But still no GPU tasks...
If there is a tag missing in app_info.xml, causing it to ignore the GPU section, what could be the name of this tag? Asking the internet, didn't find any suspects.

As a test I installed Win7 on this MB. BOINC/SETI (after a change in app_config.xml concerning the number of GPUs to use) run fine on CPU and 3 GPUs.
But, to escape the world of Windows, I'd like to crunch under Linux.

If there is a tag missing in app_info.xml, causing it to ignore the GPU section, what could be the name of this tag? Asking the internet, didn't find any suspects.

You would need to post the full app_info.xml for people to look at it.

You probably would have been better off setting up the system, and making sure it could run stock OK, then moving to anonymous platform.

That is, what I tried to do.
I assume with 'system' you mean the BOINC/SETI system and not Linux.

When searching for 'boinc', the Synaptic Packet Manager (I used it for installation) shows as installed components (marked in the first column):
boinc 7.6.31+dfsg-6ubuntu1
boinc-app-seti 8.00svn3363-2
boinc-client 7.6.31+dfsg-6ubuntu1
boinc-manager 7.6.31+dfsg-6ubuntu1
libboinc-app7 7.6.31+dfsg-6ubuntu1
libboin7 7.6.31+dfsg-6ubuntu1

I never actively moved to anonymous platform. At installation time I even didn't know what this means.
Should I de-install boinc and try again?

Are you trying to run stock apps or 'Anonymous platform' where you add the apps you want to run?

Since you don't have any executables defined , I'm guessing you are trying to run stock apps. You don't have a GPU section, so you won't get GPU tasks at all. For stock apps you don't need an app_info file.

EDIT: To switch to stock, rename/delete app_info file, abort all tasks, and restart BOINC.

For Anonymous platform there are sample app_info files included with the hand selected and downloaded files, to help you build the app_info file properly.

I never actively moved to anonymous platform. At installation time I even didn't know what this means.
Should I de-install boinc and try again?

I'd suggest detaching from the project, unistall BOINC, delete everything in the BOINC data directory, re-install BOINC & re-attach to Seti.

I have no idea how you managed to get an app_info.xml file there as it is not part of a normal stock installation.
Normally the user has to manually edit an example file (or make their own from scratch) to make it use their chosen application, then they have to move it (and their chose applications files) to the project folder.

That's what I will do as soon as I have time again to play around with Linux and Seti. Could be next week...

Thanks

This is your problem. You installed Multibeam CPU app from repository and you won't get any other apps from the server. Run down cache and report all completed work, uninstall the package and restart BOINC client if the package uninstall script doesn't do it (sudo service boinc-client restart). I'm not sure if you will need to reset the project as well.
