What version of the product are you using? On what operating system?
Pyrit 0.3.1-dev (svn r228) / pyrit-cuda 0.3.1 
Backtrack 4 Final (Ubuntu 8.10)
Nvidia Backtrack Driver Package 190.18
Core2Duo Mobile 2x2,20Ghz 

#1:  'CUDA-Device #1 'Quadro NVS 135M''
#2:  'CPU-Core (SSE2)'

Please provide any additional information below.

When I run "pyrit batch" within a TTY so without starting X-Server/KDE it
works fine.

Whats also strange is that since I installed the NVidia Drivers I only see
one Core instead of two Cores which I had seen before.

Thanks for your help in advance.

Best regards,
Flow

The NVS 135M is just too slow. The call by Pyrit is interrupted by X to prevent 
the
screen from locking up completely. There is no solution :-)

Please see the FAQ regarding the number of cores.

OK I checked FAQ ;) Thanks!

Is it really that slow? It runs with 1400PMK/s for a onboard card still fast in 
TTY 
;)
So it is too slow to handle both X and Pyrit and the X-Server does recognize 
this?!
I did not know that XServer ist that intelligent ;)

Might there be any workaround?

Thanks for the fast answer ;)

Best regards,
Flow

its actually not the X server but the driver itself. The driver detects the 
running
X-Server and enforces a five-second-timeout.

You can edit cpyrit/cpyrit.py, modify the line "self.buffersize = 4096" in
CUDACore.__init__ and set it to a lower value (e.g. 2048)

are you really getting 1400 PMK/s with that card?

i have that card and im not even getting a quarter of that amount...similiar 
spec cpu
as well
