This question already has an answer here:
My ubuntu is in trouble,
I changed my graphic card, tryed some manipulations, and now I get some problems with the login-screen.
I have the login-screen, normal, but when I type on password ( I am sure it's the good one, ssh work fine ), after I valid I get a black screen, some rapid text in textmode, but I can't read, and next the login-screen again.
I tryed to find something strange in Xorg logs, but I don't found. I am not sure to look at the good place.
My card is an ATI RS690. I use VGA for now, but I plan to use it on HDMI.
Ubuntu 13.10 / lightdm
