back and forward keyboard buttons do not work on 14.04

  • 772

Both my external and native keyboards have back and forward buttons (Thinkpad T400). I upgraded to Ubuntu 14.04 and the back and forward buttons on my external keyboard do not work. Can you help me fix this ?

xev gives 166 and 177 for the back and froward buttons on the native keyboard of my laptop but 113 and 114 for the external keyboard

If there was an automatic solution to use the right driver or mapping, I would prefer...

Thanks

14.04

  1. What you're trying to do is to cram the keys of two keyboards into one keyboard.

    How about turning the solution upside-down: try to make two keyboards work as two keyboards!

    E.g. someone who has a French and a German keyboard, defines 2 keyboards: a French one and a German one and tells Ubuntu which one is being used.

    So do the same: define two keyboards in System Settings - Text Entry, re-assign the keys as explained in this article and presto: you're up and running.

    (If your layout is QWERTY US you take "English US" and "English US, alternative international", if you have QWERTZ, you take German and Swiss, French&Belgian, ...)

  2. I think it does not depend on Local keyboard settings. I have back button on external keyboard and it is displayed 166.

    KeyPress event, serial 37, synthetic NO, window 0x3a00001,
    root 0x9e, subw 0x0, time 4815411, (-648,508), root:(540,560),
    state 0x0, keycode 166 (keysym 0x1008ff26, XF86Back), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

    As you see on keyboard layout chart there are no special buttons like forward and back defined. So it is not out of the box setup. I have USB BTC keyboard so it could help if you shared with us what keyboard model do you use.
