Debian Login Loop

Question

If I try to log on to Debian with XFCE, it will get a black and white screen in a few seconds, and then it will flash very short and return me to the login screen.

The strange thing is: if I go to the terminal using Ctrl + Alt + F1 (or any other F key), I can log in and enter the GUI using startx. Everything works as usual.

I installed Debian in the same way on 4 different machines, but none of them had this error.

I used debian-8.2.0-i386-xfce.iso to install using a USB drive.

Does anyone have an idea what might trigger this behavior?
