Определено в Руководстве по политике Debian:
The contrib archive area contains supplemental packages intended to work with the Debian distribution, but which require software outside of the distribution to either build or function.
Every package in contrib must comply with the DFSG.
In addition, the packages in contrib
must not be so buggy that we refuse to support them, and
must meet all policy requirements presented in this manual.
Examples of packages which would be included in contrib are:
free packages which require contrib, non-free packages or packages which are not in our archive at all for compilation or execution, and
wrapper packages or other sorts of free accessories for non-free programs.
2.2.3. Несвободная -область архива
The non-free archive area contains supplemental packages intended to work with the Debian distribution that do not comply with the DFSG or have other problems that make their distribution problematic. They may not comply with all of the policy requirements in this manual due to restrictions on modifications or other limitations.
Packages must be placed in non-free if they are not compliant with the DFSG or are encumbered by patents or other legal issues that make their distribution problematic.
In addition, the packages in non-free
must not be so buggy that we refuse to support them, and
must meet all policy requirements presented in this manual that it is possible for them to meet.

Эта док-станция не поддерживает альтернативный протокол отображения Thunderbolt. Вместо этого он использует DisplayLink, который... работает, если вы потратите на это время.
В Ubuntu есть официальные драйверы, включающие бинарные BLOB-объекты. Многие другие дистрибутивы переупаковывают его. Это хорошая ссылка для начала работы с подробностями и настройкамиhttps://wiki.archlinux.org/title/DisplayLinkПоддержка в 2021 году по-прежнему не впечатляет -она тормозит и требует пользовательской настройки на многих машинах, но она работает большую часть времени.
