Sorry, I only know how to apply git c source code patches onto a git repository, not a Linux OS. What I was expecting needing to do is to checkout nouveau's fixed code, build it and somehow install it over the version in the package manager/this distribution, at which point I would hopefully have a working driver. In my first post I of course meant "jessie", not "stretch" (testing). I succeeded at building nvagetbios and nvbios, but both fail: anonymissimus@debian:/media/HD3_SOURCE/envytools/nva$ ./nvagetbios WARN: Can't probe 0000:01:00.0 PCI init failure! anonymissimus@debian:/media/HD3_SOURCE/envytools/nvbios$ ./nvbios mybios.rom warning: No strap specified fopen: No such file or directory Failed to read VBIOS!
