Touching the touchpad on Linux interrupts typing

I have a laptop with Linux Mint 17 installed. Whenever I am typing and the touchpad is enabled, successive keystrokes are being interrupted. For example, if I would try to type 'paragraph', it could result in 'paraph', due to three keystrokes being ignored.

This only occurs when the touchpad is enabled, and when my palm is resting on the touchpad. If I avoid touching my touchpad, this does not occur. Mouseclicks with touchpad are disabled (e.g. tapping the touchpad does not work). The interrupting occurs both with and without palm detection ('disable touchpad when typing').

Executing cat /proc/bus/input/devices detects the following touchpad:

I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
P: Phys=isa0060/serio2/input0
S: Sysfs=/devices/platform/i8042/serio2/input/input10
U: Uniq=
H: Handlers=mouse0 event5 
B: PROP=1
B: EV=b
B: KEY=6420 30000 0 0 0 0
B: ABS=260800011000003

Can anyone help me get this to work? My goal is to be able to type with an enabled touchpad, without the touchpad interfering with my typing.

Please tell me what I should do or what information I should provide. Thank you!
