I have a Toshiba Satellite L510 with Ubuntu 12.04, I fixed this issue installing fnfx-client. And after installed, it worked automatically!!!

sudo apt-get install fnfx-client

Good luck!

sudo setpci -s 00:02.0 F4.B=X

Where x is 0-99, and 0 turns the display off. I have a Toshiba Satellite t135-S1309 and this was the only command I ever found to change the brightness. It's possible to set it up to bind to the keys or to set a brightness on boot, but I was never bothered by it to that degree. Not a perfect fix but it will change your brightness.

I had a similar problem with my Toshiba R830. What worked for me was the following changes to Grub:

Press Alt + F2 and type gksu gedit /etc/default/grub

Find the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and modify it to one of the following:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

or

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

or

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" (this is what worked for me but others had success with the former)

Save and close gedit.

Open a terminal (ctrl + alt + T) and type sudo update-grub. Reboot your pc after each try.

Hope this helps.
