I know this sounds stupid, but I installed Ubuntu on my laptop alongside Windows 10. Everything worked fine until I tried to login using the password I had provided.
It does not let me in. At first, I though that I had the wrong password. But then I tried changing my password using Ubuntu recovery in the boot menu. To be sure I didn't type the wrong password, I use 123456789 from my numeric pad. Because I was also afraid this could be a keyboard region issue. I still can't login with those simple numbers.
What could be the problem?
UPDATE: I tried solutions proposed in another post on login loop. Doing ls -lA did not work for me. However, in /var/log, I found Couldn't open module nvidia" and "Failed to load module "fbdev" (already loaded, 0).
Is this the answer? And what is the solution. dpkg-reconfigure... command from other post did not work.
