Touchpad stopped functioning

[Greens]

Running: Fedora 8
Laptop: Toshiba Satellite 1115-S103
ETC: 256MB RAM, 1.5GHz Celeron
will provide other details if necessary

I'm not sure how or why it happened. I can't recall modifying anything that had anything to do with the touchpad, but it recently stopped responding all together. Where would be the best place to start troubleshooting?

I thought it might be something in xorg.conf.. but I can't really tell. I've attached in in case there's something I can do with it to make it work.

Any help would be greatly appreciated,

That's a pretty elaborate looking Input Device section. May I suggest reverting to the original for test purposes, or did the touch pad not work originally?

[Greens]

The touchpad had been working since I installed Fedora on my laptop; it just stopped working yesterday. Where might I find what the original settings would've been? I'm actually fairly certain that all of those have been there since install(apart from SHMConfig, which is the only one I added myself -- didn't have any negative effects when I did).

I cut out everything that didn't seem absolutely necessary, but to no avail. It reads as follows now:

Section "InputDevice"
	Identifier  "Synaptics"
	Driver      "synaptics"
	Option	    "Device" "/dev/input/mice"
	Option	    "Protocol" "auto-dev"
	Option	    "SHMConfig" "true"
EndSection

Thanks for the help. Any other suggestions?

I assumed that you may have done some tweaking to the settings since that section in your xorg.conf was twice as long as the settings in my xorg.conf. It actually looks quite elaborate. Had you made the changes yourself there would have been a backup of the original file that you could have reverted to. Here's mine:

Section "InputDevice"
        Identifier  "Synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "Emulate3Buttons" "yes"
        Option      "Touchpad Off" "1"
        Option      "SHMConfig" "true" 
EndSection

The last 2 lines are part of my efforts to turn off the touchpad completely.

[Greens]

Hmm.. well your setup is essentially mine now too, minus the "Touchpad Off"/"Emulate 3 Buttons" Options, but my Touchpad isn't working. So I think the problem would have to be elsewhere on my system. Any other leads?

[glennzo]

No. Do you also run Windows or another OS where the touchpad works?

[Greens]

Presently no, though the laptop used to run on Windows XP and the touchpad worked fine(it's never been an issue whatsoever up 'til now). I suppose it's possibly a hardware failure(the laptop's very much in bad shape), but it just stopped working all together: not even with partial functionality.

Hi just a thought. but most laptops have shortcut keys to turn the touchpad off, are you sure you havent done that accidently.

[Greens]

*sigh*

..you know what, Dangermouse, that was the issue. x_x I feel so stupid now. I swear I thought I'd tried that already though. Thank's for suggesting it.

glennzo, thanks very much for your help; sorry for wasting your time. >_<

FIN,

Hey. You're not wasting my time. I enjoy this forum immensely. Love trying to help others with their Linux problems. Sometimes I'm even right
