2.6.0-test1: Synaptics driver makes touchpad unusable

2.6.0-test1: Synaptics driver makes touchpad unusable

[Ricardo Galli]

The new synaptics driver doesn't work with Dell Latitude Touchpad, it doesn't 
work any /dev/input/event?|mouse? and /dev/psaux neither (altough the same 
configuration worked at least until 2.5.70).

I tried with gpm and the X's synaptics driver from 
http://w1.894.telia.com/~u89404340/touchpad/index.html (as indicated in the 
kernel documentation) and none worked, although "cat < /dev/input/event0" 
showed garbage every time I touched the touchpad (no pun intended) iff evdev 
was loaded.

You probably need this patch.

Tried it, but still doesn't work. X server says cannot query/intialize de 
device as before:

I can replicate this problem with 2.6.0-test1 on a Dell Inspiron 4150
laptop as well.

This doesn't look like the same problem. There is no "reset failed"
message. Are you using the correct XFree86 driver:

        http://w1.894.telia.com/~u89404340/touchpad/index.html

Also, note that the driver doesn't work with gpm yet.

Does it help to make the timeout even longer? (15 seconds for example)
Does it help to disable the reset sequence altogether, like this?

No, it didn't help. With the above patch, the x server gives the following 
errors:
Query no Synaptics: 0000C8
(EE) TouchPad no synaptics  touchpad detected and no repeater device
(EE) TouchPad Unable to query/initialize Synaptics hardware.

Looks like the wrong protocol is specified in the X driver
configuration. You must set "Device" to "/dev/input/eventX" and
"Protocol" to "event", where X is probably 0 in your case.
