Special keyboard buttons not working

Hello, everybody

I have got a HP G62 notebook and some of the "special" keyboard buttons are not working ( in other words, nothing changes ).

For example:

- display chooser button ( i.e., either just the laptop, either the projector, either both, etc. )

- sound on/off button

Anyone had any experience with this ?

I have used 'xev' to determine what the keycode is i.e. xf86mute, and assigned commands to the keys using my window manager.  It has worked in gnome and fluxbox for me.

Xbindkeys is a good tool to map your keys. Use xbindkeys -k to find the code for a button you press.

Also, if you're using acpi, run

$ acpi_listen

to see what actions your keys may generate, then you should be able map each one of these actions to a command to run. Simply edit the action handler script to accomplish this:

/etc/acpi/handler.sh

Re: Special keyboard buttons not working

While the keyboard binding part might not be that hard, I am stuck with figuring out how and what to get for the VGA and HDMI port switching ( see below ).

Any suggestions for a specific application or at least an idea of what should I search for ?

xrandr is what you need.  But if you want a gui interface you may like arandr.

If you want a notification display like the one in that image, I don't know that one exists - but a couple lines of scripting should allow a four way toggle like that, and any notification system could be made to pop up a display much like that.
