The entries in your auth.log involving the gdm user appear normal. This is nothing to worry about.

That seems to be the Unknown Display issue. I've tackled that one myself and I left a link as a comment to your question on how I resolved it. Let's first make sure this is the case: Go to Settings > Displays and see if you can see an Unknown Display overlapping with your normal display.

You could check your driver for graphical card. I met almost same problem. I have tried repairing gnome-desktop-*, /etc/fstab , unity, compiz, lightdm, gdm ...nothing works. But when I use unity in terminal, it told me something wrong with fglrx. No such device. fglrx is an library package for optimization of ATI graphical card. My card is very old and can't ...

Have you tried a restart? If not do one now. I have a feeling that (from what you have said) that it will be back to normal after a restart. This is what gave me that feeling: I am currently running a 14.04_live
