Problemi tastiera, luminosità packard bell tk85

Question

Ciao a tutti, il problema di cui vi parlo riguarda linux mint 17 ma è identico a quello che avevo su ubuntu 14.04 lts. Ho dei problemi con alcuni tasti funzione della tastiera integrata del mio packard bell tk 85.

I tasti da F1 a F12 sono mappati correttamente. I tasti del volume no. Guardando dalle impostazioni della tastiera sembra che il tasto muto sia "Home" sulla tastiera, il tasto volume giù sia "Page up" e il tasto volume su sia "Page down".

Conseguentemente non posso regolare luminosità e volume tramite la tastiera. Il tastierino numerico non funziona del tutto (anche se non mi interessa tanto perché non lo uso).

Riguardo la luminosità, questa si resetta a ogni riavvio. Potete aiutarmi?

Grazie in anticipo (scusate, non so se ho scritto male l'output del comando nella domanda)

Accepted Answer

Dopo un po' di ricerche ho trovato questa pagina in cui viene spiegato come rimappare i tasti.

Per i tasti della luminosità ho modificato il file /usr/share/X11/xkb/symbols/srvr_ctrl. Nel mio caso i tasti erano F11 e F12 quindi ho sostituito

    key <FK11> {
    type="CTRL+ALT",
    symbols[Group1]= [ F11, F11, F11, F11, XF86_Switch_VT_11 ]
    };

    key <FK12> {
    type="CTRL+ALT",
    symbols[Group1]= [ F12, F12, F12, F12, XF86_Switch_VT_12 ]
    };

con

    key <FK11> {
    type="CTRL+ALT",
    symbols[Group1]= [ XF86MonBrightnessDown, F11, F11, F11, XF86_Switch_VT_11 ]
    };

    key <FK12> {
    type="CTRL+ALT",
    symbols[Group1]= [ XF86MonBrightnessUp, F12, F12, F12, XF86_Switch_VT_12 ]
    };

Per i tasti del volume ho modificato il file /usr/share/X11/xkb/symbols/pc. Nel mio caso il tasto muto era "Home", il tasto volume giù era "Page up" e il tasto volume su era "Page down quindi ho sostituito

    key  <INS> {    [  Insert                    ]  };
    key <HOME> {    [  Home         ]   };
    key <PGUP> {    [  Prior                ]   };
    key <DELE> {    [  Delete               ]   };
    key  <END> {    [  End          ]   };
    key <PGDN> {    [  Next         ]   };

con

    key  <INS> {    [  Insert                               ]   };
    key <HOME> {    [  XF86AudioMute                    ]   };
    key <PGUP> {    [  XF86AudioLowerVolume ]   };
    key <DELE> {    [  Delete                               ]   };
    key  <END> {    [  End                          ]   };
    key <PGDN> {    [  XF86AudioRaiseVolume ]   };

Poi bisogna cancellare i file xkm in /var/lib/xkb/ quindi sudo rm /var/lib/xkb/*.xkm e effettuare logout e login per attuare le modifiche.
