Can't login as users after adding extra memory and then installing new nvidia
 

Hi there,
I am using the following system: Initially I had 64 Gb memory. Then I added extra memory. After added the memories I lost the GUI (maybe there was update issue with yum). Then I downloaded and installed "NVIDIA-Linux-x86_64-331.67.run". Now the GUI is working. But I can't login as a user in the desktop using my ID and password. But I can login through ssh using the same username and password. I also can login as root and I can access all of my files. But I don't want to login as root. After adding extra memory and installing nvidia, in the /home directory there is no user.I am new in the system administrator arena. Would you please to help me.

Best Regards
Zillur

Seems to be a permission thing. Could you output, from root, the command
ls -al from /home
and ls -al /root from /

Thanks. Here is the output.

What distro are you using?

Seems you do not have a home directory for your user...
