First I just want to say I consider myself a beginner using Ubuntu. I've read through most of the forums I could find which were related to this my problem and couldn't find a method which works.

Here's what happens. When I hear the login screen sound, I see nothing but black. If I type my password to login and I hear the sound associated with logging in but the screen still stays black. If I close my laptop screen to go into sleep mode and then open it back up, the login screen is visible but then goes black after I login. I tried recovery mode and repairing packages but didn't work. I tried no splash and nomodeset but the screen just froze. Ran a system diagnostic and it gave this error message:enter image description here

for my video drive. I think the issue might have to do with the nVidia drivers I switched to before. Is there a way to fix this? Thx in advance for any help.

i had a similar issue when i installed ubuntu as a virtual machine. I was able to get the gui screen using Ctrl-F7. Ctrl key was the right side ctrl key. You can try this combination of Ctrl-Alt-F7. something similar to this Switching Between GUI and Terminal

  • Thx. I tried your key combination but nothing happened :(

  • @CapR You're already on Ctrl+Alt+F7. Try using for example Ctrl+Alt+F6 and you can switch between the 6 terminals, F5, F4, F3, F2, and the one that ubuntu also uses for booting, F1. In all of the terminals, Ctrl+Alt+F7 will get you back to the graphical interface.

  • @CapR then i think you need to uninstall your nvidia drivers and reinstall the correct version as this [askubuntu.com/questions/691946/… talks about
