Pacote para configurar o Trackpoint no Dell Latitude E6410?

Question

Eu tenho um Dell Latitude E6410 executando o Ubuntu 15.04 mais recente (consulte Detalhes no final desta pergunta). Eu acho que tenho o mesmo problema com o TrackPoint, conforme descrito em:

Drivers de mouse trackpoint / nipple / trackstick Dell vs Lenovo?

Um comentário deixado nessa pergunta é:   Drivers de mouse trackpoint / mamilo / trackstick Dell vs Lenovo?

e isso aponta para

Configurações do touchpad do Glidepoint / trackpoint no Dell Latitude

Mas a leitura desse link me deixa confuso sobre como instalar esse pacote dos repositórios do Ubuntu (e eu quero dizer instalá-lo sem muito esforço, como fazer o download e compilar a partir de pacotes fonte).

A pesquisa na Web mostra link que fala sobre um laptop certificado. E6410 não está listado.

Procurando por pacote glidepoint revela:

link

que diz que:

There is no current release for this source package in Ubuntu.

Esse é o pacote correto para instalar? Estou concluindo "não" por causa do comentário acima. Se esse não for o pacote correto, qual deles devo usar? Se for o pacote correto, então por que a mensagem "no current release"?
