Bug Description

Hey everybody
I have an acer laptop model acer as3810t
The problem I'm experiencing has been present since ubuntu 11.04 up to 12.04 beta2
the thing is that sometimes - out of nowhere (completely random. seems not related to anything) the trackpad stops responding and requires a reboot
sometimes it stops responding a minute after I login
and sometimes days can pass without me experiencing the problem.
I have no idea what causes it. I haven't seen other similar bug reports.
I believe that it is an ubuntu issue since I'm also an arch linux user. the problem didn't appear on arch.

thanks!

I'll happily send further info.

WORKAROUND:
1) switch to the console session (e.g., press <Ctrl>+<Alt>+<F1> and input your login & password as prompted);
2) reload the PS/2 kernel module:
sudo modprobe -r psmouse && sudo modprobe psmouse
3) try to exit the console session and switch to the graphic terminal (e.g., press <Alt>+<F7> or <Alt>+<F8> if VT7 is black).

I experience the same on my laptop. But I think it's related to suspend. Can usually suspend without problems, but then after one or several suspends, it stops working.

When it stops working, buttons still work.

I can add that this happens on one of my laptops, but never on the other (netbook). So I'm guessing it's hardware spesific.

hey julenissen. which model of acer do you have?
my model (3810t) can not suspend on ubuntu for years.
it's a bug that hadn't been fixed for many versions.
if I suspend my computer it suspends but it doesn't resume out of suspend.
my computer shuts down instead of quitting suspend.

In my case, touchpad hangup occurs in Precise more often than in Oneiric, Natty etc.
Interestingly, it unfreezes after suspend & resume.
---
ohad-basan, there has been a suspend/resume workaround for a quite long time: https://help.ubuntu.com/community/AspireTimeline/Fixes#Suspend_to_RAM -- just add a "i8042.reset=1" kernel option into /etc/default/grub

mouse pointer (of my Acer's AS3810T Synaptics touchpad) freezes every time I do the following things:
1) select "Switch from user..." (in GNOME fallback session, from the session menu);
2) at the LightDM screen I log in another user (e. g. Guest);
mouse cursor works in that another user session, but after switching back to the 1st user I discover the frozen pointer;
to "unfreeze" it, I need to log out from the user session (using keyboard only: <Ctrl>+<Alt>+<Del> and select "Log Out") and log in again (sometimes, but not every time, suspend & resume helps, so I don't need to log out).
---
Do you have any ideas how I can help? Should I look at some logs?

my theory is that it is related to syndaemon disabling the touchpad, because:
1. touchpad operation can be resumed by synclient and xinput cli tools
2. rmmod psmouse && modprobe psmouse also works, but likely because that reloads the synaptics driver
3. gpm driver continues to work in a console while touchpad is disabled in X
4. people have reporded that removing the "disable touchpad while typing" option from mouse settings is a workaround for this

The touchpad began to work decently.
With multiple X sessions opened, after switching from one to another, the pointer becomes responsive in less than 5 seconds.

I think it's fixed as for now; reopen the bug if you still experience a problematic touchpad behaviour.
