Not working on Toshiba l750
Probably I'm doing something wrong, but I can't get it to work on my Toshiba l750. At the moment I'm running ubuntu 12.04. I tried to install the latest version (0.74) via the .deb package. Done that I rebooted the computer. Now only after a suspend and wake can I see the bar while pressing fn keys, but there is no change in the backlight. I tried adding nvidiabl to /etc/modules for autostart, but nothing changed.
Hey. I myself have an L750 too and I have finally managed to solve the brightness issue.

Take a look at this reference which doesn't exactly match your laptop but the issue is the same.
What I did is almost the same as it's written in the linked post. Only thing you should notice is that Ubuntu 12.04 has the 3.4.1 version of gnome settings daemon, however I still downloaded the 3.2.2 source because the method of the detection of your display is changed in 3.4.1 so you can't modify it as you should.
After installing the latest package of nvidiabl, applying the changes to gsd-backlight-helper.c, compiling it, copying it into the right folder and adding nvidiabl to /etc/modules brightness controll works for me.
Of course you have to switch "toshiba" with "nvidia_backlight" and not "sony".
I hope i could help.
Please give me the output of
lspci -nn cat /sys/class/dmi/id/sys_vendor cat /sys/class/dmi/id/product_name
This way the driver will autoload without modifying /etc/modules, and follow the link given by qwe2, it is instructive!

I managed to get it to work on Fedora without a single problem. I just followed the instructions on the readme and it worked, even after a kernel upgrade. I passed to Fedora after the second attempt to get it to work on ubuntu made the screen go black on reboot(not just dimmed down since the key shortcuts were not working). The only problem now is that the computer doesn't recognize the backlight shortcuts(fn+f6 and fn+f7) but I fixed this with some custom shortcuts
Thank you for the support anyway
