en tout cas, dans stable backports on est resté sur la v535 
j’en ai profité pour jeter un oeil sur le wiki et j’ai découvert qu’il y avait un dépot nvidia.
En terme de stabilité, je sais pas ce que ça donne et j’ai toujours été frileux d’installer manuellement le pilote.
pour le matériel récent, c’est toujours compliqué. j’imagine que tu savais au moment de l’achat qu’il n’y avait pas de pilote pour ce modèle.
pour l’ouverture des sources, on a pas beaucoup avancé malgré certaines annonces.
Packaging
There are three major ways that Nvidia drivers are packaged:
-
Debian-packaged drivers: these are the most recommended drivers for most users. Other packaging methods should only be used in case these drivers cause some problems.
- Nvidia-packaged Unix drivers: these drivers are packaged as distribution-agnostic executable installer files. As such they may conflict with other components of a Debian system. They may be downloaded from Nvidia’s archive.
- Nvidia-packaged datacenter drivers: despite their name, these drivers do contain desktop components as well. They are packaged using distribution-specific methods. In case of Debian, Nvidia provided apt repos for Debian versions 10, 11 and 12, but currently only Debian-12 is still officially supported. Refer to Nvidia documentation for detailed installation instructions.
All 3 types of packaging allow to install either « open » or « proprietary » flavor for versions newer than 515. Except of issues with Debian packaging itself, problems with all types of Nvidia drivers should generally be reported to Nvidia developer forum. Reports should always include nvidia-bug-report.log.gz file generated using nvidia-bug-report.sh script. Refer to the official guidelines for reporting.
