How to locate and delete trash installs?

[Boyntonstu]

In attempting to add a 8187 adapter driver, I installed many items.

They are trash and not needed.

How can I conduct a search and destroy mission?

How did you install them?

The file /var/log/apt/history.log has a history of all items installed by apt. But this requires that you installed the software by apt and not, for example, by manually compiling it.
