           Summary: Targa Traveller 826 - unrecognised key codes
           Product: Ubuntu
           Version: unspecified
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: UNKNOWN

The Targa Traveller 826, being a laptop, provides several Fn key combinations
and special keys to do stuff. Some of them work, some of them are ignored.
Here's a list of unrecognised keys and their keycodes. If xev recognised the key
I have noted that, if kern.log is listed as source that means xev did ignore
that particular key:

Fn + F7 - Audio Volume Down : keycode 174 (xev)
Fn + F8 - Audio Volume Up : keycode 176 (xev)
Fn + F9 - Audio Mute/Unmute : keycode 160 (xev)
Fn + F12 - Sleep/Hibernate : keycode 223 (xev)
"Media Key" - Start Media Player : e012 (kern.log)
"IE Key" - Start Webbrowser : keycode 178 (xev)
"Mail Key" - Start Email client : keycode 236 (xev)
All the keys listed above are ignored and do not perform the required action.

"Bluetooth Key" - connect/activate built-in Bluetooth Device- keycode e062
(kern.log)
This key is somewhat special, as it seems to perform some type of double duty.
Although the key is unknown to the kernel, the built-in Bluetooth device does
indeed get connected/disconnected to the system when using that key. I verified
this by checking kernel logs. The BT connecter seems to be connected via USB and
kern.log contains messages that system does indeed recognise the device.

"Wireless Key" - activate built-in Wireless card - keycode e076 (kern.log)
Similiar to the Bluetooth Key, this one is ignored by xev and the kernel lists
it as an unknown key. However, if you install ndiswrapper drivers you will see
that using that key does indeed activate/deactivate the built-in WLAN card.
However, the WLAN card is a miniPCI slot, therefore you won't see any hotplug
related messages in kern.log, only the output of iwconfig changes accordingly.
On windows, this key works as a H/W-Antenna switch, activating or deactivate the
WLAN-cards antenna. The laptop has a dedicated LED to show the state of this
switch, the LED also works in Linux, no matter if a driver is installed or not.

I have tested this with kubuntu only, I don't know if the keys would work in
Ubuntu or not.
