Bug Description

after upgrading xserver-xorg-input-synaptics in natty the following happens:

1. login (via gdm), touchpad is working here on login screen
2. after 2-3 sec. no touchpad mouse movements possible (freeze)
3. gnome loads background image, but no panels etc.
4. restarting gdm from console makes the touchpad work again on login screen (gdm), GOTO 1.

Uninstalling xserver-xorg-input-synaptics helps to resolve this particular problem (login/gnome OK), although then most features do not work any more (e.g. two-finger, middle click simulation by pressing both "mouse" buttons).

I think the Xserver log is useful, I think there is a segfault logged after init of synaptics (cannot review logs in browser...). Some more info about the device and the regression follow:

This is normally a bug in some application using the D-Bus library.

Just seem to have resolved the issue by also installing gsynaptics (removed a few days earlier), now I am back to a fuctional touchpad in gnome. So it may be more a gnome issue (although unity showed same problem, freeze after login).

So this bug should be closed, I will see if problem reappears.

One more comment: installing xserver-xorg-input-synaptics immediately crashed the xserver, that may be the segfault seen in the log file (XorgLogOld.txt ...).

---Other tests below---

After uninstalling xserver-xorg-input-synaptics the Xserver log looks like this:

I can confirm that I was affected by this exact same issue. Installing gsynaptics solved it though. Interesting part is that it only affected one of my three laptops, all running Ubuntu 11.04 with Gnome Shell and the latest xorg ppa.

Thanks!

Curious why gsnaptics would resolve it - does it cause -synaptics to uninstall?

Anyway, since you guys could work around it, are you ok with that as a solution for natty, or would you like to see it properly fixed? If the latter, we'll need a full backtrace (the traces in Xorg.0.log aren't really that useful except just for proving it's an X crash.)

I might be imagining things but I don't think have this problem with the 2.6.35 kernel, but I do with the 2.6.38. I have a USB mouse which still works so it doesn't bother me and know I can boot the old kernel if I need it.

I had a reappearence of the issue with the touchpad, this time gnome was
fully working, when the touchpad stopped working. Again 2-3 sec. after
GDM login touchpad stopped working.

This time the solution was different, applied as described here (german
ubuntu wiki):
http://wiki.ubuntuusers.de/touchpad#GNOME

The touchpad was (for an unknown reason) disabled in GNOME and could be
reenabled:

# info
gconftool-2 --get /desktop/gnome/peripherals/touchpad/touchpad_enabled
# result: false
gconftool-2 --set --type boolean
/desktop/gnome/peripherals/touchpad/touchpad_enabled true

# logout, login, touchpad in Gnome OK

Now the settings are:
gconftool -R /desktop/gnome/peripherals/touchpad
 disable_while_typing = true
 config_migration_needed = false
 touchpad_enabled = true
 tap_to_click = true
 scroll_method = 2
 horiz_scroll_enabled = true

HTH,
Martin
