Eu estou usando o Debian Jessie em uma placa-mãe j3710 e os gráficos são surpreendentemente lentos.
Eu tropecei em This Thread e instalou xserver-xorg-video-intel de jessie-backports em conformidade.
Mas parece que a placa gráfica ainda não está em uso.

Como posso fazer o Debian usar a placa gráfica?

Você provavelmente também precisará de um kernel atualizado a partir dos backports:
sudo apt-get -t jessie-backports install linux-image-amd64
Você pode também precisar de firmware atualizado (de backports não gratuitos):
sudo apt-get -t jessie-backports install firmware-linux-nonfree
