Again with Synaptics Touchpad problem.


Sorry about dredging up issues with the Synaptics touchpad, however i've done everything suggested by the various threads (within and without LQ) and am at a point i can't seem to get past.

first the issue, then the configuration listings.

Running Slack 12.1, i have an external USB mouse and the touchpad working relatively well - the external scroll wheel scrolls, the touchpad touches. the problem is i'm trying to use syndaemon and the xorg.conf Options for defining the touchpad boundaries to no avail. i would say it isn't a big issue, however for some reason the current rigth boundary for vertical scrolling on the touchpad is about half an inch from the left edge ! which doesn't leave much room to actually USE the pad *.

the problem is believe is that the system thinks the touchpad is an Imps/2, and thus not loading the Synaptics driver. anyway, i'm not entirely sure of how to configure X to use an ImPS/2 driver.

forgot to mention:
i had followed the threads suggesting to change the protocol when loading the psmouse module - i removed the 'imps' option from the /etc/modprobe.d/psmouse, however this doesn't seem to have any effect for this problem.
additionally, i have the following line from Xorg.0.log when X starts:
Code:
(II) Synaptics touchpad driver version 0.14.6 (1406)
SynapticsTouchpad no synaptics event device found (checked 20 nodes)
(**) Option "Device" "/dev/psaux"
(**) Option "SHMConfig" "on"
...
Query no Synaptics: 6003C8
(EE) SynapticsTouchpad no synaptics touchpad detected and no repeater device
(EE) SynapticsTouchpad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "SynapticsTouchpad"
(II) UnloadModule: "synaptics"

thanks for any suggestions, if anyone is able to ...

go easy,

XPS 1530 has some touchpad problem too,

then

thanks for the reply.

i'll look into what exactly it is the suggestion of setting nomux=1 does -- if you could explain anything about it, that would be great.

also, would you mind explain what the difference with the xorg.conf file is ? i see you have added the Option of "SendCoreEvents" to the synatpics device section, however that isn't going to change the problem that the driver itself isn't being loaded. as a result, i'm not sure what this xorg.conf file is meant to achieve.

well, i did both of the suggestions, however X is still not loading the synaptics driver.

when i remove the InputDevice mouse0 entry in xorg.conf, predicatably, the touchpad and mouse both quit responding. the nomux boot parameter didn't seem to change anything.

sorry i was ofline for so long -- out of town travelling, which was loads of fun.

anyway, i have done as you asked about, rebooting the laptop doesn't cause any different behaviour -- whether the lid is left open or not.

however, as an update, i have somehow "solved" the problem. i built a new kernel and evidently have selected an option which correctly supports synaptics touchpad. i'll need many compile/build cycles to narrow it down to a particular config option, however at least it's working *.

now i'm onto the next problem with the laptop which is getting a native wlan driver to work, rather than using ndiswrapper.

thanks again, go easy,

-daniel
