I was used the methods which provided by debian wiki.I found that my laptop can't display the login screen after grub2 booting.The screen becoming black.But i can login it by feeling.And the nvidia drivers work well.By the way, i use the machine which model is "80WB Lenovo XiaoXin RUI7000" and the os is debian buster. And my nvidia display card is 1050 .Has anyone ever been in the same situation as me? How did you solve this problem? Please ignore my poor englist.

Some more hardware information would be helpful. Install inxi and post the result of

Code: Select all

inxi -Fx

Nvidia may also require firmware. Try installing firmware-misc-nonfree. You will need to have the nonfree repository activated first.

I've been having similar issues with Debian Sid for a few months now with a NVIDIA GTX 960. Previous to that, everything was fine.
Switching between X and the other consoles and back to X used to work just fine - now it usually locks up X.
I'm using KDE and screen locking and even screen power saving also often lock up X. Using "Sleep" can also lock-up X on restart.
I've been able to free things by switching to a command console and killing the kscreen screen saver process. This results in disabling compositing and I must then manually re-enable it, lock out, and then lock back in to get compositing working as well as various desktop effects (like cube rotation on workspace switch).
I had assumed to was either due to a KDE upgrade or a kernel+Nvidia-driver upgrade - when you use Side, you expect some transitory issues, but this one is lasting longer than normal.
Sorry to hear you are seeing something similar.
Sorry I can't be of any more help.

Appears to be Optimus dual graphics. Search the forums and wiki for Optimus, and Bumblebee which is the usual way to get it working. Apparently Prime Render can be made to work too but I don't know anything about it.
It takes a bit more configuration than just installing nvidia-driver.

@hbrand - your issue probably has nothing to do with the OP's. Please start a new topic about it instead of hijacking and distracting from this one.
