Subject: Re: JtR OpenCL - AMD GPU not listed

Hi,

Even after setting that environment variable, issue persists. I am still unable to see the GPU in the clinfo output.

I think the issue is related to connection over SSH. Because my friend is able to run oclHashcat-plus on the machine when he logs into the X. However, over SSH, the GPU is not connected.

I want to use JtR with OpenCL.

I checked the sshd_config file on the machine:

 cat /etc/ssh/sshd_config | grep "X11"
X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes
#       X11Forwarding no

X11Forwarding is set.

here is, fglrxinfo output (It does not detect the GPU either):

fglrxinfo
Error: unable to open display (null)

clinfo does not detect the GPU as well.

I am connecting to the machine over SSH using Putty over port 22. I  have checked the option, Enable X11 forwarding under SSH.

I found one more thread here related to a similar (but not the same issue):

Please try:

export DISPLAY=:0
clinfo

does it show the GPU now?
