hello again,

im having this problem, but the other way roud :)

BOINC detects my GPU (nVidia GT 220) but its unable to use it.

Currently i have SETI@home CPU tasks disabled, and only GPU tasks enabled, and i cant process any GPU WU.

Im currently running boinc 7.0.24 from official repo, under Ubuntu 12.04

any idea?

First off - IF you are running BOINC under Linux ...

I'm a newby in ubuntu (2 days) and I'm not so good in english but I'm not a newby in Boinc.
First aff all thank you for your help I've sovled my problem with the "sleep" line and the "xhost" line and sorry for my terible english.
One thing is not clear for me ... if I restart the session the isn't recognized ... I've to give the command sudo /etc/init.d/boinc-client restart every time I start an Ubunt session?

So, thank you for keeping up the spirit(s) to address this nastiness.

Now we only need a way to perform the initialisation of CUDA and friends without an installation of X at all.

Hello, Skip had sent me a pointer to his summary on the BOINC forums on
the matter and I have followed your all's instructions. So, when
6.12.23+ comes out, this should also auto-detect your graphics card.
Many thanks to you all.

Sorry to bring that posting up again, but just wanted to confirm that this problem also exists for archlinux and your solution works like a charm!!

I've got a machine running Ubuntu v10.04 x64. With fglrx installed from the repos a HD4850 works fine.

With fglrx removed and catalyst v10.8 installed from the AMD site it works fine with a HD5830 in it once you add gfarmerfr's fix into the startup script:
xhost local:boinc &> /dev/null


When I plugged in a 2nd HD5830 boinc is not seeing it:

I just put together a 9.1 x64 ubuntu system using 6.10.32 and 190.53 and on about 3 out of 5 reboots, the GTS-250 cannot be found.

An old thread at gpugrid suggested using a 5 sec delay in the "start" of boinc-client and rescheduling the task by changing the script name from S20boinc-client to S32boinc-client. Not sure if this is going to fix the problem.

Anyway, I was wondering if anyone else has seen a problem like this?

This is my first CUDA ubuntu system. All the others were VISTA 64.

Permissions. Allow the user account you normally use to find the ATI drivers. BOINC checks for a certain library file within the drivers. If your user account can't read the drivers (its path isn't in your user account's path structure), BOINC won't find the library file.

Remind me, is there a way to uninstall drivers under Linux? For it may be that you have to get rid of them, before reinstalling that will change this. Some configuration file somewhere that sets the order, that the rest is getting their information from.

The order is set by the way you insert them in your machine, the drivers you have installed and the library read by BOINC. I think you'll have to reinstall your drivers if you want to see them in the correct order as they are in the machine.

BOINC merely checks for the GPU library, sees if it exists on your system and then shows what - according to that library - is installed and in what order. It doesn't reorder anything.
