[Bug 1404332] [NEW] Touchpad cursor loses precision after VGA monitor plugged in

 

Public bug reported:

I just plug in the VGA cable. The external monitor is detected acc.to dmesg. A USB mouse works OK.
The problem lies somewhere with synaptic driver.
If I simply put down a finger on the touchpad and hold it still, the cursor still fidgets in random directions by a couple millimeter increments.
