I removed the nvidia 304.131 driver from my installed system. After rebooting I'm prompted for a new bug directly at log in. It seems to affect xorg-server, but the free desktop graphics driver (nouveau) seems to work with my nvidia Geforce GT 430 card.
I tried mkusb twice (making persistent live drives) and the zenity windows worked without any glitch. It is too early to be sure, but it indicates that there are problems with the nvidia graphics. I hope it will be fixed before 16.04 LTS will be released.
