Hello, Your graphic card can probably be managed by: - Nvidia closed-source driver (including firmware): https://wiki.debian.org/NvidiaGraphicsDrivers- Nouveau open-source driver (automatically loaded by default for your hardware) with a firmware you have to install (probably the firmware-misc-nonfree package from the non-free repository)
(you can check for potential other missing firmwares for your hardware by typing grep -i firmware /var/log/messages in a terminal/console as root)
