Notes

Tested under Mint Nadia 14 (kernel 3.5.0).

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]

No problems under Ubuntu 12.04LTS, the video problems are resolved with the newest drivers in “Additional drivers”.

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).

It seems to me impossibile to even download nvidia drivers. I have been having issues with most current distros I tested. Internet connections are always slow and unstable and cannot fetch the repositories as flawlessly as I am used to. Most often terminal will not find the packets I request and the Ubuntu Software Center will list them but fails to download them and prompts for a connection check..

Do you think there is something wrong with new distros and this network card drivers or something like that? I do not recall having issues with previous distros. I mostly tried Ubuntu-based distros.

I could not fix the brightness problem either.

I have tried under Ubuntu 12.04 and the video problems looks the be solved with the newest drivers (version 331) in the “Additional drivers” section. The fn keys for turning up/down the volume and the brightness runs perfectly.

If you only have problems with the packets, you should change the “edit > software sources” at “Ubuntu Software Center”. I have not found any internet problem with either Wi-Fi or RJ-45.

I have a L755-1ED laptop with gentoo, and when I connect a jack to the audio output the sound is heard on both outputs, though the laptop speakers volume down a bit.

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.

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.
