Hello,
and sorry for bad english, I have a few questions:
installed hashcat according to this manual
1. I can't use my first and third device at the same time??(which hashcat discovered)
i have to choose one of them?
if yes, why can't i use my third device?
3. My integrated video adapter( Intel Corporation UHD Graphics (rev 05)) cannot be used for brute-force with nvidia + cpu?
3. Is it possible to safely improve the brute-force speed?
Information about my system:
nvidia-smi
clinfo
vga adapters
test(intel(skipped) +nvidia)
Why it skipped?
Why does hashcat not want to use the third device?
test(pocl + nvidia)
PS:
Сonfig xorg.conf was not found in my system:
if I create this file, my system does not boot at all, it freezes on the logo.
