GTX 980 Ti on linux

[Suchet Bargoti]

Recently bought a Gainward GTX 980 Ti and experiencing some problems.

Desktop setup:
Dual boot - windows 8 + Ubuntu 14.04

1) Bios doesn't show up, takes a lot of time to read grub screen (at least 1 min)
2) Installed the following driver [352.09] http://www.nvidia.com/download/driverResults.aspx/86276/en-us
as recommended by nvidia.
I run 'nvidia-smi' and get:
+------------------------------------------------------+
| NVIDIA-SMI 352.09 Driver Version: 352.09 |
|-------------------------------+----------------------+----------------------+
| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |

+-----------------------------------------------------------------------------+
| Processes: GPU Memory |
| GPU PID Type Process name Usage |
|=============================================================================|

+-----------------------------------------------------------------------------+
The name is Graphics Device - not GTX 980 Ti. It is recognising other specs of the card though.
3) A more focused question -- can't run cuda [6.5] enabled tasks.

Note: have been able to install the latest driver on Windows [353.06] and the graphics card is running fine.

Other hardware components
PSU: Thermaltake Smart 650W 80+ bronze
CPU: Intel Core i7-3820 3.6Ghz
Motherboard: MSI x79A-DG45(8D)

On which linux build?

On Ubuntu 14.04 I had issues with cuda/opencl too. After readon the web and installing and trying out everything, it worked someday. Besides that you need something called nvidia-352-uvm or similar. And I remember that I had to create a device or something and it had todo with modprobe. I really don't remember what it was exactly and I did not understand everything. But this was the key point. The cuda/opencl support is broken in 14.04. Probably it was like this:

Hope, someone else can help you better with this opencl thing. And not all applications support opencl. I wanted it to work for Darktable and it is lightning fast now.
