Source: firmware-nonfree Version: 20160110-1 Severity: wishlist Starting with the Maxwell GM20x generation[1], NVidia graphics cards require signed firmware for most operations, the Nouveau driver does not provide acceleration without the firmware.
In February 2016, NVidia finally made the firmware available in the linux-firmware git repository, and with Linux 4.6 and Mesa 11.2 (both currently in experimental) users should be able to get acceptable performance out of their expensive cards without having to resort to the proprietary driver. 1. https://nouveau.freedesktop.org/wiki/CodeNames/#NV110
