[Tip] How many Non-free software is on your machine ?

[Mark]

I get:

mar at markbase:~ $ vrms
              Non-free packages installed on markbase

nvidia-173                NVIDIA binary Xorg driver, kernel module and VDPAU lib
virtualbox-3.2            Oracle VM VirtualBox

              Contrib packages installed on markbase

flashplugin-installer     Adobe Flash Player plugin installer
nvidia-common             Find obsolete NVIDIA drivers

  2 non-free packages, 0.1% of 1688 installed packages.
  2 contrib packages, 0.1% of 1688 installed packages.

I found this a little confusing because I have the nvidia 260.19.12
driver installed, which does not show, and I explicitly removed the
173 driver some time ago, but it is still here.

Interestingly, I have the free, non-open-source version of VirtualBox installed.
