SUMMARY


STEPS TO REPRODUCE
0. You have nvidia GPU
1. Install "nvidia-driver" from deb.debian.org via apt
2. Reboot
3. On Login screen, try to log in.

OBSERVED RESULT
The login scrren went black, and revert to login screen. The user is unable to login.
Selecting "X11" under the selection menu workaround the problem, but this situation is not noob-friendly at all.

EXPECTED RESULT
The login screen is an important GUI. Please don't crash.
