touchpad periodically freezes in Ubuntu 11.10
The touchpad on my Dell 1420 Inspiron laptop has been periodically freezing since upgrading to Ubuntu 11.10. The mouse
works fine and after a restart, the touchpad works again. Thank you for any solutions to this problem.

I've seen this alot in 11.10, but only on the first start after a fresh install.
From what I have seen the touchpad freezes up and does not respond until you reboot, after that it works like a charm.
It has happened to all the machines I have installed 11.10 to, or witnessed others installing it to.

I have a similar problem on my Dell Inspiron. The relevant output in my case is as follows:

If you run:
sudo modprobe -r psmouse; sleep 2; sudo modprobe psmouse
Does it freeze again after the command

Ran actionparsnip sudo.
Didn't freeze until the next reboot.
Then it consistently freezes immediately after entering the keyring password prompt.
Got out of this by un-checking the "Disable touchpad whilst typing" box in touchpad properties.
I don't have a real mouse but ALT key combinations work when the touchpad is frozen.

ok then run:
gksudo gedit /etc/rc.local
and add the line:
modprobe -r psmouse; sleep 2; modprobe psmouse
add it ABOVE the exit 0 line, save the new file, close gedit and reboot
May help

I ran the commands suggested by actionparsnip and the touchpad unfroze. AIUI this is simply removing and restarting the mouse kernel driver. While this is a handy work around I assume there is something that is causing the driver to stop responding in the first place. What is the best way to pursue this enquiry further?

Could report a bug. Does adding the command in rc.local help any?

I did add the commands to rc.local but it seems that this runs only at power up/login. My touchpad freezes at any arbitrary time (and rarely at login) so rc.local modification won't do it for me. Looks more like a genuine bug to me :-(

I am content to leave this with the "Disable touchpad.
However, if you would like me to do anything to help with your diagnostics, I will do it.
Many thanks for your help.

I have the same problem with my MacBook 4.1
The trouble periodically happens after I suspend my laptop. After my Macbook wakes up, often my touchpad freezes.
I nerver has this issue with Ubuntu 11.04. I have this problem since my upgrade to 11.10.

I'm having the same issue on my Apple MacBook Pro 8.1 (early 2011) when running the Ubuntu 11.10 Live CD.

From reading different forums I see this problem seems to be affecting quite a few people. I can't find a bug for it though, is there one? The workaround seems to be to untick "disable touchpad while typing" - I suggest any reports that aren't fixed by this are a separate bug.
For me the problem occurs on Travelmate 5720 and is sporadic. It mainly occurs during use of Terminator - I suspect that is because that is the time when I am most heavily using the keyboard.

For the travelmate, try:
gksudo gedit /etc/modprobe.
and add the line:
option psmouse.proto=imps
Then reboot to test

dave@westy3:
option psmouse.proto=imps
(psmouse.conf is a new file)
Well it's certainly no worse with this setting - as to whether the freeze problem is fixed only time will tell, sometimes I don't see the issue for days or even weeks.

option psmouse.proto=imps does not fix it for the Travelmate.
Infact modprobe psmouse gives
WARNING: /etc/modprobe.
It's worth noting that ctrl-alt-F1 can be used to get the command line in order to get control back if you loose the pointer and can't get to a terminal window easily. Then
sudo rmmod psmouse
sudo modprobe psmouse
Then ctrl-alt-F7 to get back to the desktop.

Ok my mistake, run:
gksudo gedit /etc/modprobe.
and change:
option psmouse.proto=imps
to:
options psmouse.proto=imps
Save the new file, reboot to test

I'm sorry the previous code was wrong , thats works:
#! /usr/bin/env python
import os
import time
def unfreeze():
print 'unfreeze'
os.
while True:
time.sleep(600)
unfreeze()

in addition to synclient, it seems
xinput <id of touchpad> set-prop "Synaptics Off" 0
also restores touchpad operation. it guess this is a bug of some sort with "syndaemon":
syndaemon - a program that monitors keyboard activity and disables the
touchpad when the keyboard is being used.
for some reason, my laptop had 2 syndaemons running while this problem occured (it has happened many times before but i hadn't checked). I'll instrument the syndaemon with some logging and see if i can get definite proof that it is causing the failure.
