I have two partitions on my sony laptop , 4 GB for OS and rest for /home dir ofcourse with some amount left for swap.
I have upgraded ubuntu 10.04 LTS to 12.04 LTS In my 10.04 installation ,before upgrade, the userid was "sashank" which was the only user in which all my files were there ( in /home/sashank)
After upgrading, the user id I gave for administrator was "sherry". I could login with this id, However I added another user "sashank", though if I try to login with "sashank" am not able to go beyond login screen.
How can I login as sashank and have access to /home/sashank as before the upgrade?
Any help would be greatly appreciated.
