```sh

# Add your user to the 'video' group to be able to use the GPU.
|
|
# You'll still need the correct drivers to be installed.
|
|
sudo usermod -a -G 'video' 'username'
|
|
sudo gpasswd -a 'username' 'video'

hashcat -b
|
|
|
|
# Run a benchmark on all hash modes.
|
|
hashcat -b --benchmark-all

# Show the expected speed for a particular hash mode.
