Workaround: I recommend installing Beyond Compare first. Then do your 12.10 to 13.04 upgrade.
If you experience this problem create a new account. Make sure the new account is in the sudo group. Log in as new user. gksu bcompare Open the old home directory and the new home directory in bcompare bcompre will show you any and all .whatever files and directories that are different between the two. Tell bcompare to copy any that are different from the new home directory to the old home directory. This will include .conf and .Xauthority. You should now be able to log in as the old user. You may need to chown some of the copied files though I haven't done this part yet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1114418 Title: Cannot login from old 12.10 user in raring Status in “lightdm” package in Ubuntu: Confirmed Bug description: I install 12.10 and upgrade to 13.04 today. I have a user called "shakaran" where I can login in 12.10. After the upgrade, I cannot login with my user shakaran in 13.04. When I enter the credentials it tries to load, but it shows a quickly black screen an return again to lightdm login. Switching with Alt+F1, I try to search a explanation in logs, then I found in /var/log/lightdm/lightdm.log: [+39.05s] DEBUG: Greeter start authentication for shakaran [+39.05s] DEBUG: Started session 2495 with service 'lightdm', username 'shakaran' [+39.06s] DEBUG: Session 2495 got 1 message(s) from PAM [+39.06s] DEBUG: Prompt greeter with 1 message(s) [+39.12s] DEBUG: Greeter start authentication for shakaran [+39.12s] DEBUG: Session 2495: Sending SIGTERM [+39.12s] DEBUG: Started session 2496 with service 'lightdm', username 'shakaran' [+39.12s] DEBUG: Session 2495 terminated with signal 15 [+39.12s] DEBUG: Session 2495 failed during authentication [+39.13s] DEBUG: Session 2496 got 1 message(s) from PAM [+39.13s] DEBUG: Prompt greeter with 1 message(s) So it is failing the authentication with signal 15. Then I try to make another user called "angel" with: sudo adduser angel I switch back with Alt+F7. Then I can login the user "angel" but still I cannot login with my old user "shakaran".
