[Pkg-utopia-maintainers] Bug#535196: hal: Thinkpad X61: RADIO button (Ctrl-F5) does not work anymore

[Leszek Koltunski]

Package: hal
Version: 0.5.12~git20090406.46dc48-2
Severity: normal

in my thinkpad X61, all 'extra' buttons work with exception of the 'Ctrl-F5' , 
which is supposed to toggle all radios (bluetooth&wifi)

To debug it, I have followed procedure given in 

 https://wiki.ubuntu.com/Hotkeys/Troubleshooting

and here's what I have found:

1) 'xev' does not see anything when I press Ctrl-F5

2) using 'hal-find-by-capability --capability input | xargs -n1 lshal -u' 
I have concluded that the thinkpad extra keys are device /dev/input/event6.

3) utumno:/dev/input# lshal -u /org/freedesktop/Hal/devices/computer_logicaldev_input_4

  input.xkb.layout = 'us'  (string)
  input.xkb.model = 'thinkpad'  (string)

  linux.device_file = '/dev/input/event6'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'input'  (string)
  linux.sysfs_path = '/sys/devices/virtual/input/input6/event6'  (string)

4) utumno:/dev/input# input-events 6
/dev/input/event6
   bustype : BUS_HOST
   vendor  : 0x17aa
   product : 0x5054
   version : 16641
   name    : "ThinkPad Extra Buttons"
   phys    : "thinkpad_acpi/input0"
   bits ev : EV_SYN EV_KEY EV_MSC EV_SW

waiting for events
00:46:45.490685: EV_KEY KEY_RADIO pressed
00:46:45.490708: EV_SYN code=0 value=0
00:46:45.490714: EV_KEY KEY_RADIO released
00:46:45.490719: EV_SYN code=0 value=0

- as we can see, 'input-events' sees the 'Ctrl-F5' keypress.

5) utumno:/dev/input# cat /usr/include/linux/input.h | grep KEY_RADIO
#define KEY_RADIO		0x181


At this point we see that the 'KEY_RADIO' is mapped to 0x181, which is > 255, 
and that is the reason why X does not see this key. 

At this moment, https://wiki.ubuntu.com/Hotkeys/Troubleshooting recommends filing 
a bug against hal, which is what I am doing :)
