Since I've installed the nvidia-drivers package, when I lock the screen by running xflock4 it goes to a blank screen with a flashing cursor in the upper left hand corner.

The system becomes completely unresponsive and I can't even switch to the terminal.

I am running Debian Buster.

I switched to the newest kernel image. (4.13.0-1-amd64 at the time of writing)

Running nvidia-detect told me to install the nvidia-driver package. I have the latest version installed (384.98-3)

My graphics card is GeForce GTX 1060

I needed to run nvidia-xconfig.

sudo apt-get install nvidia-xconfig

Thanks for the Info. I'm on Debian Testing (Buster) too and I had the same problem. After locking the screen with xflock4, tty7 was not accessible anymore. nvidia-xconfig fixed it for me as well. Now there is a xorg file under /etc/X11/xorg.conf.

I found something similiar here.
