How to disable or change the timeout limit for the GPU under linux?

Question

Does anybody know how to disable or change the timeout limit for CUDA kernels under Ubuntu 12.10? (With current versions of Windows one can set the timeout limit in the registry.)

Please tell me as well if there is no possibility to do this with Ubuntu.

The only results of my previous search are the following:

• running the CUDA kernel without a graphical display is attached to the GPU
• splitting the kernel into smaller ones to avoid exceeding the time limit

Both solutions are no option for me because I need the graphical display for my application and there are already no threads running sequently after another during the kernel is executed. And splitting the single threads will cost months of work. Please do not ask further for the details in these directions.

Thanks for your help in advance.

You can disable the watchdog by modifying your Xorg config (Option Interactive "0"). An example is available in the answer to this question: CUDA Visual Profiler 'Interactive' X config option?
