[Bug 803610] [NEW] synaptics touchpad upgrade freezes X directly after login

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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:

hwinfo --mouse
> hal.1: read hal dataprocess 9464: arguments to dbus_move_error() were incorrect, assertion "(dest) == NULL || !dbus_error_is_set ((dest))" failed in file dbus-errors.c line 280.
This is normally a bug in some application using the D-Bus library.
