Same issue here. I found 2 solutions:
1. Use lightdm as DM. 2. Revert the glx diversions with: > sudo apt-get install -t testing glx-alternative-nvidia/testing glx > -diversions/testing nvidia-kernel-dkms/testing nvidia-driver/testing > libegl1-nvidia/testing I didn't tried with today update yet, maybe the issue is fixed?
