Sun Type 6 Keyboard

I’ve written about my issues with my SUN Type6 keyboard in the company. I’ve finally found a 100% satisfactory solution. In the end, all fiddling with xmodmap and setxkbmap didn’t really help. To really fix my issues I needed to edit the file /usr/share/X11/xkb/keycodes/evdev to shuffle some keycodes around. In the end I made these changes (relative to the directory /usr/share/X11/xkb/keycodes):

   *        =   evdev

With the above changes I was additionally able to modify the file /etc/hal/fdi/policy/10-x11-input.fdi so that HAL will do the right thing, once this keyboard is plugged in (see the line with input.product).

<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.keys">
      <merge key="input.xkb.rules" type="string">evdev</merge>
      <merge key="input.xkb.layout" type="string">de</merge>
      <match key="input.product" contains="HID 0430:0005">
        <merge key="input.xkb.model" type="string">type6</merge>
      </match>
    </match>
  </device>
</deviceinfo>

Make sure, that your desktop environment uses the system settings and doesn’t override it with session local settings, when you log into your desktop. If everything is correct, the /var/log/Xorg.0.log should contain something like this:

...
(II) config/hal: Adding input device HID 0430:0005
(**) HID 0430:0005: always reports core events
(**) HID 0430:0005: Device: "/dev/input/event0"
(II) HID 0430:0005: Found keys
(II) HID 0430:0005: Configuring as keyboard
(II) XINPUT: Adding extended input device "HID 0430:0005" (type: KEYBOARD)
(**) Option "xkb_rules" "evdev"
(**) Option "xkb_model" "type6"
(**) Option "xkb_layout" "de"
...

While the above changes may be the 100% solution, there is still the danger, that the changes are overwritten, when new keyboard tables are installed. For Gentoo Linux it is therefore advisable to extend the CONFIG_PROTECT variable in /etc/make.conf with the directories /usr/share/X11/xkb/keycodes and /usr/share/X11/xkb/rules.

The simplest solution however may be to copy the file /usr/share/X11/xkb/keycodes/evdev to a new file /usr/share/X11/xkb/keycodes/evdev-new, edit the keycode changes into this file and then load the keycodes by executing “setxkbmap -keycodes evdev-new(type6)” somewhere in the login process (.xprofile or .xinitrc or whereever).
