O primeiro programa que precisou acessar a placa, *POUTZ*, perdi o acesso aos dispositivos:

NVIDIA: could not open the device file /dev/nvidiactl (Permission denied).
NVIDIA: Direct rendering failed; attempting indirect rendering.

Serial number of failed request: 1226
Current serial number in output stream: 1226

chmod 0666 /dev/nvidia* && chown root /dev/nvidia*
