Failed to change the screen brightness of the laptop.
Finished checking that by changing the brightness of the screen, either reducing or increasing the TTY's stay in black.
I therefore believe that the bug is there. Not on anything else. Of time that I realize now I've found this bug.
I sincerely believe that only by raising the brightness or turn down the brightness fails.
Right now, with kernel 3.2.20 and nvidia 295.59.
Of course, regardless of use DPMS or not.
You already have a hint of failure.
You have a figure.
