I am currently using the system76 Z35Fm and I find that the Fn+F5 (Brightness Minus - Dark Sun) and Fn+F6 (Brightness Plus - Bright Sun).

I was looking for the keycode for these two combinations.
I have followed the wiki - https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch to find out what the ErrorLevel/KeyCode was for these two combinations.

Method 1:
The Keyboard shortcuts do not produce any response to the combinations.

Method 2:
Through the terminal screen, I tried running the "showkey" command and ended up getting 0x9c (return key release) for both combinations.

Method 3:
Since I am unable to get a keycode I tried going low level and getting an APCI event generated from these combinations. Using the "tail" command, I got frustrated from the lack of response I got. I'm guessing that the even was not received by the kernel.

By asking around I found that this may be caused by a buggy DSDT file (which may need to be manually configured for this machine). I wanted to check if there was an update to DSDT from system76, so I checked the knowledge76.com wiki and found that the system76 driver is not installed on this particular machine (recognizable by looking for System>Administration>System76*).

Will try downloading and installing http://planet76.com/repositories/system76-driver-2.1.1.deb
Will report with changes.
