Hello, with the kernel 4.1 in backports it is not possible to use the fglrx drivers. Please check bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=795230 The use of testing 15.7-3 is working well here, but it's in testing and not in backports. Is it possible to add it in backports, so we can use the gfx-card with kernel 4.1 without using testing/unstable? Cheers... Pierre
