Hey.
I have an old Packard Bell with a upgraded CPU AMD 2 x 3 GHz processor and a CUDA able Nvidia GeForce 6800 GT gfx, standing in a wardrobe, with Ubuntu 14.04. I don't use the computer to other things than Boinc projects. Propretarian Nvidia drivers I use. According to http://boinc.berkeley.edu/wiki/GPU_computing my machine would be able to use GPU on Seti@home.
But how do I do, to activate GPU calculation? Think I have all CUDA package I have found in synaptic.
boinc-nvidia-cuda
nvidia-profiler
nvidia-cuda-toolkit
nvidia-visual-profiler
nvidia-cuda-gdb

BOINC are version 7.2.42 (x64), default from apt.

In the Boinc manager under "Properties of project SETI@home" it says, under Scheduling, "Don't fetch tasks for NVIDIA GPU -- Projects has no apps for NVIDIA GPU

I also run climateprediction.net, but they are not able to use GPU in there projects, but that should SETI@home do.

Here are some information on me and my machine. May you see the information?
User ID 10027841 http://setiathome.berkeley.edu/show_user.php?userid=10027841
Compuer ID: 7332229 http://setiathome.berkeley.edu/show_host_detail.php?hostid=7332229

PS. There are also a VGA gfx on the mother board, but I have inactivated it in Bios. May It be better to use that for the display, instead the extra GFX, or may it only get problems?

Seti does not have a default CUDA or OpenCL application for GPUs. Only for Windows and Macintosh.

Not according to this, is says windows and linux only. http://boinc.berkeley.edu/wiki/GPU_computing

Seti has an Astropulse application for Linux, but not the standard Multibeam one. Which is what it says for you:

In the Boinc manager under "Properties of project SETI@home" it says, under Scheduling, "Don't fetch tasks for NVIDIA GPU -- Projects has no apps for NVIDIA GPU

Astropulse are only available when the tapes have just been loaded, like now.
They need to be separately enabled in the project preferences:
Run only the selected applications:
SETI@home v7: yes
AstroPulse v6: yes
Of course, you'll also need to enable the Nvidia GPU in the project preferences. And do that on the correct venue (location).

And I was wrong, there is no GPU app for the Mac.

Thanx.
I also deselect "Use CPU, enforced by 6+" in SETI@home preferencces.

I have also deselected SETI@home enhanced, should I do that?

My CPU-cores work with climatechange.net.

I don't under stand this:

"And do that on the correct venue (location)."

There is box 'Location' at the bottom of computer page:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=7332229

(the old name for Location is venue)

Also 'separate preferences for .....' can be set on:
Computing preferences
SETI@home preferences

If you changed the 'Location' of the computer and you have created 'separate preferences for [that Location]' make sure to change/look at the "correct venue (location)"
