Touchpad e Kernel 2.6.xx

Introduzione

Questo Howto spiega come far funzionare il Touchpad con il Kernel 2.6.xx Ho un Laptop Asus serie L3, finché avevo su il Kernel 2.4.22 il Touchpad funzionava decentemente, ora che ho messo su il Kernel 2.6 il touchpad ha cominciato a darmi delle grane, funziona si, ma ha perso la funzione del tasto a pressione ed è divenuto anche meno preciso.....

Preparazione del kernel

Ho risolto utilizzando i driver Synaptics, questa è la procedura: 1) Selezionare come Built In nel Kernel:

in device drivers
in input device support
  - event interface
     select mice
         - PS/2
         - synaptics touchpad

Compilate e installate il vostro Kernel.

I driver Synaptics

Installare i driver Synaptic, i binari dell'ultima release la trovate qui ( http://w1.894.telia.com/~u89404340/touchpad/files/synaptics-0.12.2.tar.bz2 ).

Dopo averli decompressi con tar xjvf nome file entrate nella cartella e date i soliti

# make
# make install

a questo punto vi avrà copiato il driver synaptics_drv.o nella cartella

/usr/X11R6/lib/modules/drivers/

Modifica di XF86Config

A questo punto vi rimane solamente da modificare il vostro XF86Config seguendo le istruzioni che trovate nel file INSTALL presente nella cartella synaptic. Per chiarimenti vi posto le sezioni interessate del mio file di configurazione.

# For most OSs the protocol can be omitted (it defaults to "Standard").
# When using XQUEUE (only for SVR3 and SVR4, but not Solaris),
# uncomment the following line.
# Option "Protocol" "Xqueue"
# Set the keyboard auto repeat parameters. Not all platforms implement
# this.
# Option "AutoRepeat" "500 5"
# Specifiy which keyboard LEDs can be user-controlled (eg, with xset(1)).
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a European
# keyboard, you will probably want to use one of:
#
# Option "XkbModel" "pc102"
# Option "XkbModel" "pc105"
#
# If you have a Microsoft Natural keyboard, you can use:
#
# Option "XkbModel" "microsoft"
#
# If you have a US "windows" keyboard you will want:
#
# Option "XkbModel" "pc104"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#
# Option "XkbLayout" "de"
#
# or:
#
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#
# Option "XkbOptions" "ctrl:swapcaps"
# These are the default XKB settings for XFree86
#
# Option "XkbRules" "xfree86"
# Option "XkbModel" "pc101"

P.S. io ho rimosso completamente la configurazione x il vecchio mouse lasciando solamente quella riportata nel file INSTALL. Ricordatevi di aggiungere, nella sezione moduli, la linea

Load "synaptic"

Credo che, se selezionato come Builtin, vada anche senza questa linea, ma io ce l'ho messa lo stesso.... si sa mai...... Inoltre dovrete rendere gli Identifier Uguali sia nella configurazione della sezione InputDevice che in quella dei Server Layout. controllate il mio file x capire meglio ^_^ Divertitevi....

Conclusione

Questo che ho scritto è quello che mi avrebbe fatto piacere trovare come tutorial quindi, non avendolo trovato, ve lo scrivo io, spero di poter essere utile a qualcuno ^_^
