When i execute pyrit inside X my screen turns black, also it does not respond to me trying to close X. Have to restart box to restore X. Upon start up I tried pyrit selftest/benchmark which were all great. 12000 k/s. Self test ok. However I get a seg fault with anything I run bascially. I have tried nearly every application that has cuda support with the same result. Aircrack-ng was giving me a different error iirc. However with X dying everytime i try to use CUDA I do not have a screen shot of the error. Hopefully when I fix CUDA with the other applications it will work with aircrack-ng as well.
