galera! fui tentar instalar o driver da NVIDIA e olha o log:
ERROR: Unable to find the development tool `cc` in your path; please make sure
that you have the package 'gcc' installed. If gcc is installed on your
system, then please check that `cc` is in your PATH.
ERROR: Installation has failed. Please see the file
'/var/log/nvidia-installer.log' for details. You may find suggestions
on fixing installation problems in the README available on the Linux
driver download page at
www.nvidia.com.
o gcc eu tenho instalado; verifiquei o kernel headers e o build-essential também! o que pode estar faltando?
