Summary

The Gyration GYR3101US remote is identical in style to the Fiire Chief. The keys are not mapped as nicely as the custom-designed Fiire Chief, though. The Gyration's firmware can be updated to gain similar functionality, though, using the Xmodmap program (and its corresponding config file) .

The Gyration remote control uses the gyro feature just like the Fiire Chief and the Gyration mouse. (The major difference is how the remote is detected and used by LinuxMCE, of course.)

Availability

• Circuit City -- US$37 (May 2008).

• New Egg -- US$99 (April 2008).

Default capabilities

• When the device is plugged in, it is identified and configured as a GO Wireless USB device. The "gyration mouse" bit works immediately. By default the Stop button will stop media playback, and the skip forward and back buttons work. If this is all you want, you're done. No further configuration is needed.

• By default LinuxMCE recognizes the volume up/down keys, the 10 number keys, the MCE button, and the media controls play/stop/ffwd/rwd/pause/skip fwd/skip back.

How to Setup

• Gyration codes: Gyration-GYR3101US-codes

• I wanted the "Ambience" (Volume/Lighting) control key mapped, as well as the Channel/Chapter function, and the pull up menu for watching/listening to media.

• To enable the volume control, I used the xev application from the KDE desktop terminal window, and identified the required keys.

xev

The first time this is run, it will pop-up a test window. Specify your mouse there, and then press the buttons on the Gyration remote to see the results in the terminal. Pay special attention to the

keycode

entries -- they are what you will specify in the .Xmodmap file.

On my particular setup (which I think is the default) the keys show up as:

Volume Up   keycode 176
Volume Down keycode 174
MCE button  keycode 97

Now the keys in LinuxMCE that provide the volume/channel/menu functions are:

F6 = Channel/Chapter FFWD/RWD/PAUSE menu
F7 = Menu button
F8 = Volume/Lighting button "ambience"

Update to get more MythTV functionality

MythTV Keys

P = Pause  # Pause key on remote
R = Record   # Record key on remote
Z = 30 second skip # Right skip key under directional pad
Q = 10 second back   # Left skip key under directional pad
I = Info   # Info button
F9 = Mute   # Mute button
Y = Switch Cards   # Pictures button
PgUP = Fast Forward   # FFWD Button
PgDOWN = Rewind   # RWND Button

Using this info, I created the following .Xmodmap file as root user in /etc

cd /etc
sudo vi /etc/.Xmodmap

/etc/.Xmodmap

keycode 176 = F8
keycode 174 = F6
keycode 97 = F7
keycode 110 = P
keycode 177 = R
keycode 153 = Z
keycode 144 = Q
keycode 134 = I
keycode 160 = F9
keycode 237 = Y
keycode 180 = PgUP
keycode 152 = PgDOWN

Now after creating the file, make sure it is loaded when LinuxMCE starts up. To do this add the following (as root) to the script file /usr/pluto/bin/lmce_launch_manager.sh:

sudo vi /usr/pluto/bin/lmce_launch_manager.sh

Add a line before the line KDE_DEBUG=1 so that it looks like

xmodmap /etc/.Xmodmap
KDE_DEBUG=1

Save the file. You have two choices to get it going.

• 1. Fire off the command

sudo xmodmap /etc/.Xmodmap 

(This must be done from the KDE desktop term window (Konsole), as it needs to be run in the X environment. (You can also export the display like: export DISPLAY=:0;xmodmap /etc/.Xmodmap .)

• 2. Restart the core.

By placing the file in the lmce_launch_manager.sh script, anytime the core is rebooted, your settings are automagically set up.

Troublshooting

Problem: There are a couple of oddities to that I have encountered. When I watch a movie and want to change the volume or lighting for a movie (or pre-recorded program), it does what it supposed to. But when I watch Mythtv live, pressing the volume up on the Gyration remote invokes the MythTV Sleep Timer.

Solution: This can be resolved by remapping the sleep timer key using the Mythweb application located at http://core.ip.address/mythweb/ (for internal open systems) or at http://core.dhcp.server.adress/mythweb/

This can be avoided by unmapping the following keys in Mythweb/Settings/Controls

F6
F7
F8

Unmap these keys. Make sure you scroll down the whole list, as they appear more than once.

After you have completed these steps the following keys will perform these functions:

• MCE button pulls up LinuxMCE menu system
• Volume Up button brings up the "Ambience" controls during media playback
• Volume Down button brings up the Channel/Chapter Fast Forward/Rewind and Pause functions
• The Gyration center button does movement correctly
• If you double click the center button, the mouse stays active, but remember to click once more to turn off (or you'll kill the batteries).
• The Gyration Left button acts like the left mouse button for "Choose" functions
• The Gyration Right button is the "exit" or "clear item" button
• The left and right buttons are just like mouse buttons
• The Number keys work with MythTV
• The Pause button will pause MythTV
• The Record button will start an on-the-fly-recording
• The skip forward button does the standard 30 second skip correctly
• The skip back button does the 10 second back skip correctly
• The fast-forward and rewind buttons function as they should
• The Pictures button will switch tuner cards if you have more than one. Nice for DVB users who don't use VDR.
• The Mute button functions correctly
• The Info button functions correctly
