I did two tests. One with the kernel installed with Ubuntu 12.04 (3.2.0-23-generic-pae) and the mainline kernel (3.4.0-030400rc6-generic-pae). I attach the important images of these tests. For information, I was able to reboot my computer with the both kernel. I don't know why when I log in with lightdm I can't reboot.
