After I created a standard user account, unable to login with that user account.
My Admin account has no problem logging in.
Look I don't have enough reputation to comment, I'll remove this clarification once it's clear... (please don't downvote)
- Is your login showing "incorrect password" or just loops back to login screen in the (no message)?
- What is the details about graphics & corresponding drivers?
Tip: Include system info (not personal data) while asking a question. Install neofetch for crisp output:
sudo apt install neofetch
If the login screen just loops back without any message please follow the steps below:
Press Ctrl+Alt+F1 and login into the shell.
ls -lA | grep 'Xauth*'. you'll see the line
-rw------- 1 root root 53 Nov 29 10:19 .Xauthority
then you need to do
chown username:username .Xauthority and try logging in (you may also need to do the same for for
ls -ld /tmp. Check for the first 10 letters in the left: they should read exactly so:
drwxrwxrwt 15 root root 4096 Nov 30 04:17 /tmp
Else, you need to do
sudo chmod a+wt /tmp and check again.
Now press Ctrl+Alt+F7 to reach the login screen again, and restart.
