I have recently installed Linux mint 13 Xfce and have run into a problem I've experienced with several other mint and non-mint Linux distros. Almost every few minutes my mouse pointer(using a touchpad) will freeze and/or become extremely erratic(zoom all over the desktop selecting things at will).(My usb mouse works fine though and this occurs with it connected and unconnected). This is always accompanied by the following output from dmesg:
Code: Select all

I've tried changing the sensitivity of the touchpad using the 'Mouse and Touchpad' application and I've also tried fiddling with gpointing-device-settings but to no avail. (gpointing-device-settings has recently started crashing on execution with a segmentation fault). I've also tried the following workaround:

rmmod psmouse
modprobe psmouse
