I installed Ubuntu 13.04. I notice that when I lower the brightness there is a lowest brightness point and when I lower further than that the brightness will increase. And why every time I restart the computer the brightness value goes to default.

And what is the question here? Please ask a question, not simply describe a problem. – mondjunge Oct 9 '13 at 12:11
Try this command:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"
