I recently upgraded from 64 Bit Ubuntu Linux 14.04 to 14.10, and as a consequence BOINC Manager 7.2.42 (x64) no longer recognises that I have an nVidia Geforce GTX770 GPU installed, and hence no GPU Tasks run; everything was fine before the Upgrade. Note that:-

1. The 'Additional Drivers' option under the System Settings 'Software & Updates' option shows I am using the recommended NVIDIA binary driver version 331.89 from nvidia-331 (proprietary, tested).
2. The Ubuntu 14.10 'Details' option under System Settings shows the GPU is present.
3. BOINc's recommended check for a GPU by running the Command "lspci | grep VGA" reports "01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 770] (rev a1)", so this suggests a GPU is present.

I am using Linux Kernel 3.13.0.37-generic. I note that Ubuntu have twice attempted to upgrade this to a newer Kernel, but to date this has failed.

Any ideas?

Hi, I recommend you read my comment on the thread "Debian / Ubuntu / Mint / Derivatives - GPU fixes recognition" to solve the issue of missing GPU Boinc running on Ubuntu. Greetings.

There is something wrong with the 331 driver package. Simply use the earlier driver, which is, I believe, 304.

Thank You. It works when I downgraded the driver from 331 to 304.
