Ten years ago? Bloomin’ heck! Still as this still seems to get frequent hits, I suppose quick update is in order – I no longer use the Unicomp “naked” but go through a Soarer converter which is an easier way of mapping the keys and allows macros to be added.<\/em><\/p>\n

Thanks to these guys<\/a> (the thread eventually gets to the meaty details), I have changed my Unicomp 122-key keyboard (UB40T56) from a funky “be friendly to Windows IBM Terminal emulators” mode into something a little more interesting. Specifically each key should be sending a unique keycode – which if you select the right model from Unicomp, you’ll get.<\/p>\n

This can be done by opening up the keyboard and removing the jumper from JP3 (just below a small chip and close to the scroll LED). In addition, it is strongly suggested that you set the kernel parameter “atkbd.softraw=0” which can be done with Ubuntu 10.04 with the following :-<\/p>\n

    \n
  1. Edit \/etc\/default\/grub<\/em> and change the variable GRUB_CMDLINE_LINUX_DEFAULT<\/em> to include “atkbd.softraw=0” at the end of what is already there.<\/li>\n
  2. Finish editing and run grub-update<\/em> and finally reboot.<\/li>\n<\/ol>\n

    Without this, showkey -s<\/em> only shows the scancodes of keys that the kernel knows about – not what scancodes are sent by the keyboard! It is possible to show the unknown scancodes by enabling the i8042 module debug mode, but atkbd.softraw<\/em> does the same thing more effectively.<\/p>\n

    This is currently a work in progress, and will need further checking before it can be taken as gospel, but …<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
