Sorry, I meant is that package installed on your system? You can verify in Synaptic or please report what the following command shows in terminal:
Code:
dpkg-query -W -f '${status} ${package} ${version}\n' | grep xfce4-powerRe: where is the backlight dimmer? - dansar - 05-16-2016
install ok installed xfce4-power-manager 1.2.0-3ubuntu4.1

I found something...When I right click on the task bar I clicked on "+add new items"...in that menu there is a brightness plugin....I added it to the taskbar but when I hover over the icon I get "no device found"...Dan

Did the xbacklight command that I posted yesterday work for you? Just trying to track down the issue.
Re: where is the backlight dimmer? - dansar - 05-16-2016
I assigned keys ctrl+1 to xbacklight +10 and ctrl+2 to xbacklight -10. Neither key combinations worked. As for the %'s I did not do that. I'd rather have a control working properly as it does in Xfce Mint 17.3 on this machine. Dan

I understand, however I am trying to diagnose if this is X server or hardware related. If you don't mind, please run xbacklight -set 50 to reduce the backlight. If it works, simply run xbacklight -set 100 to set it back to 100%.
Please also post the results of this command:
Code:
for interface in /sys/class/backlight/*; do echo -e "\n $interface"; cat $interface/{brightness,max_brightness,actual_brightness}; doneRe: where is the backlight dimmer? - dansar - 05-16-2016
I get this.....dan@dan-HP-G60-Notebook-PC:~$ xbacklight -set 50
No outputs have backlight property
dan@dan-HP-G60-Notebook-PC:~$
Re: where is the backlight dimmer? - Mike - 05-16-2016
Interesting. What about the second command?

Whoops, it doesn't look like you pasted the whole command. The easiest thing to do is to click on the Select link above the code to highlight the entire command. Then right-click and paste into the terminal.
