Can't login (keep getting redirected to login after entering correct login)

[THESEXPISTOL]

Hi guys,

I'm having an issue here, after i enter my correct login info, my screen gets black for 2 seconds and then i'm redirected again to login screen and asked to login again and so on...
I logged in tty and entered 'startx' but i get this error

xauth: error in locking authority file /home/myusername/.Xauthority

Before getting this problem, i had my caps lock on and missed a few times my login on text mode, then i rebooted and this happened.

Can't use the system because of this...

Can someone help me?
Thanks

I've removed .Xauthority and now when i login the login menu gets stuck and a terminal opens in the corner of the screen with my user logged in.

i then type
myusername$ startx

and the output is:

X: user not authorized to run the X server, aborting.


Please help!

Is there some way through ubuntu livecd to reinstall the system without losing the files in home folder?

Try:

sudo startx

If you are with lightdm, try switch to gdm with

sudo service lightdm stop
sudo service gdm start

It works for me and it's a temporary workaround

[steeldriver]

it sounds like your ~/.Xauthority file ownership or permissions got messed up

go into one of the virtual terminals by hitting Ctrl-Alt-F1 (or Ctrl-Alt-F2 etc), login as your normal user, and type

sudo /home/myusername/.Xauthority

or

sudo rm ~/.Xauthority

then

exit

and then Ctrl-Alt-F7 to get back to the GUI login screen, and try to log in normally again.
