Notes

Screen brightness with NVIDIA card:
Laptops with this graphic card are unable to change the brightness of the LCD screen, to be able to turn down from the desktop controls (fn keys do not work), you have to follow these steps:
@ sudo nvidia-xconfig [Generates a X configuration file in ”/etc/X11/xorg.conf”]
@ sudo gedit /etc/X11/xorg.conf [Edit the file, add “Option “RegistryDwords” “EnableBrightnessControl=1”” (remove 1st and last quotes)between “Section “Screen”” and “EndSection”]
@ sudo reboot [Restart]
Summary
Almost everything runs out of the box, you have only to correct the brightness problem in some models. In addition, the fn keys does not execute any action with some shortcuts (brightness for example).
Discussion
I'm assuming that when you say there's too much brightness that you are referring to the inability to adjust the brightness. I too have experienced problems in this regard. I have the l755 with a nvidia geforce gt 525m, using linux mint 14, and after searching around I managed to get the brightness control working (though the fn+f6 and fn+f7 still don't function).
I had to use the proprietary nvidia drivers and ran “sudo nvidia-xconfig”, which generated a x configuration file in ”/etc/X11/xorg.conf”. I opened this using “sudo gedit /etc/X11/xorg.conf”. I then added “Option “RegistryDwords” “EnableBrightnessControl=1”” (remove 1st and last quotes) beneath “Section “Screen”” but before “EndSection”. After reboot brightness control functioned.
Aside: I have not tested whether or not this will work without the proprietary drivers by generating the xconf file using “X -configure” in recovery mode, copying the file from /root to the correct location, and adding the above line to it (this occured to me afterwards).
Thank you!
Same graphic card, and your solution works :).
About the fn, I think that could be possible to bind the keys with a script and control the brightness. I have to try it…
Hey guys! I'm trying to install linux in my l750-1ez, but I have not found any solution in google to correct the LCD screen problem (there's too much brightness).
Anyone have found a solution? I've tried to change the brightness by terminal (toshnet, acpi_tool and /sys brightness file), recompile the kernel adding toshiba modules, update the BIOS and edit the grub.cfg (adding'acpi_backlight=vendor'). But It still doesn't seem to work.
