OpenCL Kernels and GUI hangs

Hi all,

When i try to run an opencl kernel on my gpu(ATI Mobility Radeon HD 4500 series), the entire gui hangs, but pops back up as soon as the kernel execution is finished. So can anyone tell me a way to load the fglrx driver(so that I can use opencl) but do not use it for rendering the desktop(which is done by the CPU instead). I shall be very thankful.

write kernels which doesn't take long time to run. or break dataset to smaller piece and run it on more batchs.
