I have a Toshiba l755 laptop, and I installed 12.04 64bit on it. The default brightness of the laptop is set to maximum value, and I can't change it.

Hello and welcome to my third issue posting. I am running ubuntu 12.04 on a compaq cq62 laptop and the brightness keys do not work using fn+f2 and f3.

If I try to shutdown my computer it simply takes me back to the login-screen.
I looked around and found :
Type in terminal:
1. sudo gedit /etc/default/grub

4. Save the file and close the file.
