Warnings in hashcat v3 not present in cudaHashcat v2.01 - should I care?

I have a similar setup as you guys do. Running into the same problems. Here is what I did to resolve. Hopefully this helps...

Attempted to run xhost + in terminal, received MAGIC COOKIE error. This confirmed that .Xauthority has issues.

I found the path to the auth file that X was using with the following command:

Code:

ps awwux | grep X

for me, this path was:

Code:

/usr/bin/X :0 vt7 -nolisten tcp -auth /var/lib/xdm/authdir/authfiles/A:0-IFUW01

I then set XAUTHORITY to the proper path:

Code:

export XAUTHORITY=/var/lib/xdm/authdir/authfiles/A:0-IFUW01

then I was able to perform the following X configurations:

Code:

xset -dpms
xset s off
xhost +

After performing the above (and installing libxnvctrl0 and libxnvctrl-dev) I was able to have hashcat control fan speed with no errors.
