For those sticking with Ubuntu on the Teres, here is a simple way to ensure all your installed software is free (as in freedom). Note Teres is free by default.

vrms is a painless way to check your system. List info for the vrms package with:

sudo apt-cache show vrms

As you can see this package is a "virtual Richard Stallman"  who checks Ubuntu or Debian for non-free software. Someone can correct me if vrms is available on Gentoo or others.

If that sounds useful, then:

sudo apt install vrms

Simply run with:

vrms or maybe vrms -e and check out the man page.

Also you can check in the System drop down menu > Preferences > Hardware > Additional Drivers
The bottom of that window should tell you if any proprietary drivers are installed.

Finally you can also use dpkg:

dpkg-query -W -f='${Section}\t${Package}\n' | grep ^non-free

That dpkg command should terminate with no output if there are no non-free packages found.

vrms is lightweight enough that the truly cautious could run a check at every terminal startup by adding it to .bashrc Hope that's useful!


Nice. There is a gentoo version too,

$ perl vrms-gentoo
          Non-free packages in teres
