[Solved] cant login in main user
[Solved] cant login in main user
i have just turned on my laptop this morning and, when i reach the login page, i enter my user name and pin, the screen goes black and then it goes back to the login page.
im currently logged in the root user and that's how im able to send this message.
anyone have any idea on what's going on and how it can be fixed?

Re: [O/S] cant login in main user
Does it work if you make a new user?
Then try to log in with the new account.
Code: Select all
# adduser yournewusername

Re: [O/S] cant login in main user
when i tried that, the screen went black and never went back on.
now, if i turn on my laptop, i can only login in command line mode.
i was able to read only one error during the boot and i run the command suggested and took a photo of it:

Re: [O/S] cant login in main user
Critical part of message seems to be:
Hallvor's command will show you where the problem is.

i tried to uninstall a couple of apps and that immediately switched from command line to gui.
however, as you can see from the result of the command shared, the disk is still almost completely full.

Re: [O/S] cant login in main user
I generally use filelight in KDE to get an overview of the disk usage, but another option is
This will list all files above 100 megabytes in the home directory and its sub directories. Hopefully you'll find the problem.
Code: Select all
find /home -type f -size +100M -exec ls -lh {} \;

Re: [O/S] cant login in main user
Do you have backup on the same disk as system?
“ computer users can be divided into 2 categories:
Those who have lost data
...and those who have not lost data YET ” Remember to BACKUP!
