Hi, Bryce
I can't speak english very well, that's why it is difficult to me to explain some things correctly
After switching on the netbook and booting ubuntu, I reduced the screen brightness to minimum. After the second reboot the netbook have retained fixed brightness as I have set before the second reboot. Now the operating system considers that the new reduced level of brightness is a maximum level, and ubuntu does not allow to increase the brightness to the origin high level. After restarting the netbook by switching it off and on the fault disappears.
