X freeze, its second time it happend. On previous versions of ubuntu everything was ok - but - I wasnt using touchpad (synaptic touchpad didnt work for me), under 12.04 synaptic touchpad finaly worked for me.
Freeze happens when I work with Libre Office writer, When Im writeing something fast, possibly with my hands on touchpad.
Why i suspect touchpad?
