hashcat Forum

Got this error today after an apt-get upgrade and apt-get dist-upgrade so something broke..
Since it worked before the update I know it's not really a problem caused by Hashcat but I hope someone can guide me in backtracking this issue
I run hashcat through optirun and it worked until I updated system

Please try with any other OpenCL program (not CUDA)

But it did work before they updated the Nvidia Cuda and opencl driver. 
For my use it's pointless to use another opencl since CUDA is what I want to use. 
And no other opencl have ever worked with my bumblebee setup

prehaps after updating and upgrading ur system with apt, ur hashcat version was upgraded aswell (happen to me to) from 2 to 3, since v3 dont use cuda anymore it wont work with out opencl, i guess if u want to use hashcat with cuda u will have to go back to V2

https://hashcat.net/files_legacy/cudaHashcat-2.01.7z

Same version as when it worked so there is something else that's broken. 
No other app complains just Hashcat. 

Before 3.10 I had no luck at all with Hashcat. 
Maybe add a function to use CUDA directly since OpenCL is a huge source of error it seems.

Is there any test program for OpenCL so I can test and dump result here?

Hmmm, really strange that no other OpenCL complains just Hashcat...
And one more thing, Hashcat 2 cuda version works perfect, why stop support for one of the most popular graphic cards out there?

OpenCL seems pretty buggy for most Intel HD/Nvidia setup so please add support for CUDA again so we don't have do dissect our computer every time.

I have exactly the same problem, after upgrading NVIDIA driver to 367.44. Until that hashcat 3.10 was working OK.
Now:

Old cudaHashcat 2.01 is working perfectly well:

Predator, I've found a solution! I suppose you are running Debian or Ubuntu based system...
1. If you don't have it already - install synaptic
2. Open Synaptic and do a search for packages with version "367.44-1" , than install all of them without the package "libgl1-nvidia-glx"
3. At last I have installed  :

and removed:

The result:

Hi,

I'll try that later today, thanks for your information about this.
