Numerous client errors / compute errors WUs on 1 of 6 computers

(moderation:
Four of my computers are running Ubuntu 9.10 with Boinc 9.10.17. The one with all the errors has a Nvidia GeForce 9500 GT GPU that runs CUDA just fine on Seti@Home. All the Errors under E@H are related to CUDA. Here is a link to the client:

The errors are right at the beginning of each WU that gets this error.
Any ideas?
Thanks in advance for any assistance provided.

It may be your nVidia driver. ABP2 requires a driver with cuda 2.3 support. You'll need driver >= 190, which isn't in the ubuntu 9.10 repositories.
Have a read though this thread, it covers a couple of options for updating to the latest drivers
E&H CUDA WUs were working
)
E&H CUDA WUs were working fine up until March 31st. Updated my NVidia driver to 195.36.15 on March 28, same day I upgraded to Ubuntu 9.10 x64. Also running Boinc 6.10.17 x64. Reinstalled Nvidia driver yesterday and waiting to see if that makes a difference. This problem is (hopefully was) causing me to run through my daily quota of Work Units. Just wondering if this has something to due with OS being 64 bit and E&H applications are 32 bit. Should run fine except may be missing a driver or library file. Stderr doesn't say anything is missing, just having problem accessing CUDA device. CUDA still working fine on Seti@Home version 6.08.
Will read through link you provided when time permits. Thanks for your assistance.
BTW - I'm a newbie to the E&H forums. How do you create a link in a thread? Tried in opening the new thread, but didn't work. It just isn't obvious to me.

In any answer window, you'll find a blue link to Use BBCode tags to format your text, above the rules.

RE: Just wondering if this

I run Ubuntu 9.04 64bit, munches ABP2cuda23 WU's without a problem. Page here covers the extra libs required for 64bit Ubuntu, basically -
sudo apt-get install ia32-libs libstdc++6 freeglut3
If this doesn't work, next option may be upgrading BOINC to a later version. I'm running 6.10.37 (unstable). I see 6.10.44 is now the stable version, as of 19-March. Crumbs!
All is well now. Back to

All is well now. Back to crunching away on E&H with Cuda. Must have been something associated with the Nvidia driver. Did say "yes" to the OpenGL 32-bit libraries this time. Wonder if the 32-bit Cuda app needed them? Guess I'll leave that one up to experience. Believe we can call this problem SOLVED!
Thanks for all the great input!
