Synaptics Touchpad troubles again!!

ken · 2012-05-03 01:20:23

G'day there One & All,

I have a HP Pavilion g6 laptop with Statler installed. I used unetbootin to install, and the live version worked fine. I then installed, and found that my touchpad no longer works. Well actually it did but it threw the cursor all over the place whenever I typed. I looked up various solutions (thankyou Mr Google) none of which seemed to apply. Somewhere amongst my searching through the filesystem I've done something but dunno what. I don't recall editing or deleting anything, but my touchpad no longer works at all. A usb mouse is fine, but the touchpad is dead. I've searched through the forum, but can't find what I need to do. I did learn that xorg.conf is deprecated, but that doesn't really help me.

Can someone please point me to where I can find the settings files or some sort of clue to how to get it working?

ken@epona:~$ dmesg | grep -i mouse
[    2.385017] mice: PS/2 mouse device common for all mice
[    3.612096] generic-usb 0003:1241:1166.0001: input,hidraw0: USB HID v1.10 Mouse [HID 1241:1166] on usb-0000:00:1a.0-1.1/input0
[    6.703303] psmouse: Unknown parameter `proto-imps'
ken@epona:~$ dmesg | grep -i touch

lsmod can find neither "touch" nor "syn", so I'm guessing there's something missing but I don't even know where to look.

A search of filenames in /etc finds nothing, a search of /usr brings up a few header files and nothing else. It's got me stumped, so any help or a pointer to where I can find somethign will be gratefully appreciated. (The synaptics site had nothing I could see; the site, whose name I forget, that used to hold a community derived driver is no longer operating).

I just woke up, so this may not be the best thought out advice, but:

A quick google of "synaptics touchpad debian" led me to http://wiki.debian.org/SynapticsTouchpad which shows that packages.debian.org/xserver-xorg-input-synaptics is something you need -- can you check if you've accidentally deleted it?

I get the jumping around mouse thing too (I have a Thinkpad X220), I think it's because my palm brushes against the touchpad. Disabling tap to click with gpointing-device-settings (if I recall correctly) makes it less annoying when I do it, but if you find a better fix, I'd be interested.

Could it not be an ALPS touchpad?

xinput --list and cat /proc/bus/input/devices
will give you more info about the touchpad.

See http://wiki.debian.org/XStrikeForce/InputHotplugGuide

I found that page before, and tried the recommendations without success sad

However, it's always possible that I've stuffed it up. I've just reinstalled the package to make sure, but I'm pretty sure it was there anyway.

I couldn't find them before, because I didn't know where to look, but I've now found the 50-synaptics.conf file.

It says:

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "On"
EndSection

...which I think is correct.

I get the jumping around mouse thing too (I have a Thinkpad X220), I think it's because my palm brushes against the touchpad. Disabling tap to click with gpointing-device-settings (if I recall correctly) makes it less annoying when I do it, but if you find a better fix, I'd be interested.

Most certainly if I find something other than a complete reinstall I'lllet you know smile

Thanks for your help,
Ken

The problem is similar, though the 50-synaptics.conf looks a bit different. Maybe you want to backup your file and use the one posted there (try also changing the Identifier back to "touchpad catchall"). Check the mentioned ev-dev file, too.

Sigh... tried what was posted there, with & without the ev-dev modifications. All I did was to stop the Xserver from loading sad

Still working on it, so those with a clue, please continue to post!!

Thanking all of you for your help

Can you show

ls /etc/modprobe.d

?

Edit: You'll probably have a file inside there named touchpad.conf or so. Probably this file will have the entry

options psmouse proto-imps

As root, open the file and change the content to

options psmouse proto=imps

Reboot or apply the sexy double

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps

Here 'tis:

libpisock9.conf
linux-sound-base_noOSS.conf

Applied those commands and the result is:

FATAL: Module proto=imps not found.

-----[ DISREGARD!!!!! ]-----

I put a "-r" in the second modprobe by mistake. I reran it, and I'm back where I started with the touchpad working, but the cursor jumping all over the place.

Syndaemon - i 2 now gives:

Unable to find a synaptics device.

So it's an improvement, but a problem still.

Still willing to try any ideas you may have smile

Thank you very much for your assistance.
Ken
