I cannot login to my main user account. I have entered the password right. When I enter the password correctly, the ubuntu login window freezes for around 3 seconds and then just returns to the login screen. When I enter a password incorrectly, it instantly tells me the password is incorrect.
When I try pressing CTRL + ALT + 1,2,3, and log in, it will successfully login, but not allow me to enter commands and then will timeout at about 15 seconds and log me back out.
I went into recovery mode and I was able to log into my main user account there. While I was in there I created a new user. I logged into the new user successfully while out of recovery mode. I went back into recovery mode and added it to the sudoers list sudo adduser sudo.
TL;DR for above, CTRL + ALT 2 does not work, created a new accout with sudo privs via recovery options
Now that I can login with my new test user account and it is added to the sudoers list... I don't really know what else to now. I really want to be able to login to my main account, unless there is a very good way to ensure that I recopy 100% of my files on user account to the new user account.
NOTE: I leave my PC on at night (with sleep mode turned off) and I found it frozen, so I restarted it and then this happened
Note: not using nvida, using AMD gpu
