运行时 API 错误 38：未检测到支持 CUDA 的设备/Ubuntu 黑屏

Question

I am currently trying to fix the following error:

Runtime API error 38 : no CUDA - capable device is detected.

I tryed to apply the advices given here: CUDA-capable device And I also tryed to apply other ones from the web.

The main issue is: when I rebooted my computer now, Ubuntu starts with command lines (with id and pass).

But I don't manage to get the Ubuntu usual desktop interface.

When I do CTL + ALT + F6 (or F something) then I can see something related to graphics drivers [fail] ed.

Do anyone know how to fix/restore the previous/initial Ubuntu graphics driver to come back to the previous state ? I do use a Nvidia Geforce 620.

I am currently using the "try" version on the Ubuntu CD to write this message to you, I could not do it other way since I don't even access the Ubuntu desktop, because of this issue.

I believe there is a better solution than recovering the data and format/resetup, so I am ready to try, the thing is, I don't know how I could fix this issue with the use of command lines.

Thanks a lot in advance.

RESOLVE UBUNTU/ZORIN - LINUX OS BLACK SCREEN

This is a gnome graphic error. I think window display manager got corrupted as it can't read the display libraries. I had this problem on my zorin o 15.3 & when I researched i found that xserver needs to be reinstalled.

Step1 : Enter to tty2 (Ctrl + Alt + F2) & login with user credentials

Step2 : sudo apt-get autoclean

Step3 : sudo apt-get install --reinstall xserver-xorg

Step4 : If you get dpkg interrupted msg, run sudo dpkg --configure -a , else proceed to next step.

Step5: Reboot your machine - reboot
