** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Description changed:
I am running Kubuntu 12.10 on a toshiba Z835-P330 laptop.
+
+ Upgrade to mainline 3.8-RC1 kernel does not fix this bug
From within windows, the keyboard command "FN+Z" turns on and off the
keyboard backlight (retrolight). From within linux, the command does
nothing.
Setting the backlight in the bios to "always on" turns on the backlight
always, which works, but is not ideal as I have to restart to turn on or
off the backlight.
I can provide any dumps of hardware or anything needed.
Also, I can provide the windows driver for the backlight if that is
helpful.
Nothing shows up in /var/log/syslog on press of FN+Z, but other FN
combinations do show up.
Here is the output from xev.
