Bug Description
***** Bug Description *****
I upgraded from jaunty to karmic yesterday (10/30). The touchpad on my sony vaio SR220J stopped working. No response to any movement, no cursor, unless I add an external USB/bluetooth mouse.
This is what I found from dmesg:
dmesg | grep mouse
[ 1.051678] input: Macintosh mouse button emulation as /devices/
[ 1.162601] mice: PS/2 mouse device common for all mice
[ 13.603905] psmouse: Unknown parameter `synaptics_

***** Diagnosis *****
Because of this mesg in the logs:
psmouse: Unknown parameter `synaptics_
the psmouse module was not loaded - I checked using 'lsmod'.
***** Workaround *****
The file /etc/modprobe.
options psmouse synaptics_
This seems to be a temporary fix to load the psmouse module with this parameter (most probably required in Jaunty). Maybe this parameter does not exist in the module version in karmic. Anyways, I commented out this line and rebooted.
the 'psmouse' kernel module is loaded and my touchpad is recognized now. Yay!
***** Possible Fix *****
I think the file '/etc/modprobe.

Update: I found the reason and a possible fix for this bug.
Because of this mesg in the logs: resume_ reset'
psmouse: Unknown parameter `synaptics_
the psmouse module was not loaded - I checked using 'lsmod'.
I searched for "synaptics_ resume_ reset" and came across the file /etc/modprobe. d/psmouse. conf which had this line: resume_ reset=N
options psmouse synaptics_
This seems to be a temporary fix to load the psmouse module with this parameter (most probably required in Jaunty). Maybe this parameter does not exist in the module version in karmic. Anyways, I commented out this line and rebooted.
the 'psmouse' kernel module is loaded and my touchpad is recognized now. Yay!
I think the file '/etc/modprobe. d/psmouse. conf' should be deleted on upgrading to karmic.
