No, it is not. I never touched setup. As I wrote before more then
once, the problem arises after upgrade, not as result of setup changing.

You are wrong: it is about divert and not about alternative.

This does not helps and can't help, because again and again: it is
not setup problem, it is upgrade result. Downgrade helps. That is
what I am doing to get it working:

dpkg -P nvidia-kernel-support
dpkg -i glx-alternative-mesa_0.5.1_amd64.deb glx-alternative-nvidia_0.5.1_amd64.deb glx-diversions_0.5.1_amd64.deb libegl1-nvidia_340.93-1_amd64.deb libgl1-nvidia-glx-i386_340.93-1_i386.deb libgl1-nvidia-glx_340.93-1_amd64.deb libgl1-nvidia-glx_340.93-1_i386.deb libgles1-nvidia_340.93-1_amd64.deb libgles2-nvidia_340.93-1_amd64.deb libnvidia-eglcore_340.93-1_amd64.deb libnvidia-ml1_340.93-1_amd64.deb nvidia-alternative_340.93-1_amd64.deb nvidia-driver-bin_340.93-1_amd64.deb nvidia-driver_340.93-1_amd64.deb nvidia-kernel-dkms_340.93-1_amd64.deb nvidia-vdpau-driver_340.93-1_amd64.deb xserver-xorg-video-nvidia_340.93-1_amd64.deb

And nothing else.
