My answer seems to have disappeared. I summarize here. "modinfo nvidia-curred" works well. CUDA libraries are installed. For nvidia-cuda-toolkit, nvidia offers SDK packages for Ubuntu, not for Debian. I don't like to get into troubles with Ubuntu, which, unlike LinuxMINT, is not compatible with

Yes. Also, # apt-get remove nvidia-kernel-dkms # apt-get install nvidia-kernel-dkms (which, in the year 2011, served to clear the driver at /lib/modules/2.6.38-2-amd64/updates/dkms. But now the kernel was 3.2.) left the issue unaltered. # modinfo nvidia ERROR: module nvidia not found $ dpkg
