Comment 4 for bug 944415

Disabling geis support from unity with the attached patch fixes this, is the problem higher up in the stack than x-x-i-synaptics? Given that the highest unity uptime I've had today since switching to precise X is 40 minutes and I've been stable with unity with this patch for 5 hours it seems safe to think that. I built utouch-geis from the latest upstream source i could find (https://code.launchpad.net/~bregma/utouch-geis/lp-937021) but no luck getting more info from it or averting the crashes.
