yeah i've already done that:
development tools like make and gcc are installed: both are installed
* the linux-headers package matching the installed Linux kernel is installed linux-headers-2.6.17-11-generic installed on its last version
* the pkg-config and xserver-xorg-dev packages are installed Both installed and on its last version
* the nvidia-glx package has been uninstalled with the --purge option and the file /etc/init.d/nvidia-glx does not exist. I did: sudo dpkg --purge nvidia-glx and there's no /etc/init.d/nvidia-glx
If you use Ubuntu, please also ensure that the linux-restricted-modules packages have been uninstalled. Alternatively, you can edit the /etc/default/linux-restricted-modules configuration file and disable the NVIDIA linux-restricted kernel modules (nvidia, nvidia_legacy) via:
unistalled every linux-restricted-modules pakage and edited /etc/default/linux-restricted-modules adding:
then installed... but no luck!...
I've also updated BIOS with the same exact results....
