full support for touchpad: remove/insert psmouse module
 
Hi,

I have Fujitsu-Siemens Lifebook S6120 with ALPS touchpad, and debian 5.0. While booting the system, the touchpad somewhat works but more advanced stuff like scrolling is missing. /proc/bus/input/devices shows not touchpad whatsoever. However, when I remove and insert 'psmouse' module, I get full support:

Code:
marit:~# rmmod psmouse
marit:~# modprobe psmouse


Now I have toucpad in input devices:
Code:
marit:~# cat /proc/bus/input/devices

...

I: Bus=0011 Vendor=0002 Product=0008 Version=7322
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio4/input0
S: Sysfs=/class/input/input8
U: Uniq=
H: Handlers=mouse1 event7
B: EV=f
B: KEY=420 0 670000 0 0 0 0 0 0 0 0
B: REL=3
B: ABS=1000003
I have experimented adding 'psmouse' to /etc/modules, I have also tried different protocols. So long with no success.

Can I somehow make this stuff automatic, or, even better, to fix the stuff without any need for fiddling with modules?

Try using the Synaptics touchpad package.

otoomet 03-25-2009 01:41 PM
How can synaptics package help if kernel does not see the touchpad?

I tried to insert "rmmod psmous/modprobe psmouse" to /etc/rc.local. Seems not to work. How can I send a message to system log from rc.local to debug?

otoomet 03-28-2009 03:02 AM
rc.local does not seem to help. The file is executed, it waits 5 seconds betweeen removing and inserting the module but it does not help. However, if helped to log into the single-user (no X) mode, remove/insert the module manually, and switch to the full mode thereafter.

Any idea how could I remove/reload a module automatically, either at boot or while logging in?
