i am using ubuntu 11.10 and i once i logged in and the screen flashed for a sec and came back to the same screen it is happening again and again. i put the ubuntu cd and almost reinstalled it while i got this thought "lets try again" i tried again and luckly it came. i immediately came here without another log off and asked you guys. how do i correct it such that i wont be having problems in future?????
Thanks Ryan McClure!! I had the same logging in problem and it worked for me!!
I had the same problem as rakshith after when ubuntu hung-up while using firefox.I tried many times, but the same log-in screen flashed again and again. After reading this post, i tried Ctrl+Alt+F1 and deleted the .Xauthority file, rebooted it and my next log-in succesfully brought up the GUI.
I also was returned to login screen, but for me it was xorg configuration issue. Here is the solution:
I was able to run Xfce manager. Then i run from terminal or alt+f2:
go to 'X Server Display Configuration', click 'Reset' button, then 'Save to X Configuration file' In new window uncheck 'merge..' option and click 'save' button.
