May be the driver has a setting to set the repetition rate ?
My one reakts with a long touch like preesing the right mouse button. So I was also forced to set that time longer to be able to hold down the touch buttons for longer.

I will look into the keyboard repeat settings to see if that changes anything, I'll have to look it up as I've only ever used windows so no idea where those settings would be but I'm sure google will let me know.
