Well that's cause half the questions that are mandatory on the form are like greek to me!

Its actually a very small issue - the FN keys for brightness adjustment don't work - volume does work - but not brightness. If I start the machine without AC power it starts dim and I cannot adjust it manually. It does not become bright on its own when I switch on power in between.

The only way is to start the PC with AC power to get full brightness. So the Function keys for brightness would help. Kindly advise.

Hi Naraayan,

Thanks for your reply. Unfortunately we require more information to find the problem. And in order to collect that information you will have to run some commands on the terminal.

But we can help you translating the greek and we have a lot of patience :)

The instructions that you will find at https://wiki.ubuntu.com/Hotkeys/Troubleshooting are only a series of commands that you will have to type on the terminal.

First, go to Applications>Accesories>Terminal and enter the command:
killall gnome-settings-daemon gnome-power-manager

That will finish some applications that take the input from keyboard. So now you should be able to start the troubleshooting.

The next step is to enter on the terminal:
xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'

A small window will be opened. Try to adjust the brightness with that window focused. If a keypress event is recognized, the code for that event will be printed in the terminal.

We need you to tell us if there was a keypress. And if so, what is printed to terminal. If there was no keypress, you should continue troubleshooting on step 4.

In case of doubt, just ask.

thanks,
pura vida.

This is what happened - I think I am getting the hang of what you experts
are testing. Though the key-press logged an event - nothing on screen in
terms of brightness changed.

So we now know that the function keys are working - but the function key is
not changing the brightness for some other reason - if my simpleton mind is
moving logically :)

Let me know what next - I feel like I am some in some Hollywood writing code
for some movie already :)

Thanks dude,

Hi Naraayan,

The commands I send you should have created some files:
udev-db.txt
dmesg.log
lsinput.log
xkbcomp.txt
xkbmap.txt

You will find them on your home directory if you just opened the terminal and typed the commands.
Please attach them to this issue.

thanks.
