Disable Synaptics Touchpad Tap Clicks in Linux 
7

I installed Ubuntu Linux on my HP nx9600 laptop and found that the mouse pointer sometimes jumped to another location as I was typing, making my typing continue where I didn’t intend any typing to occur. Also, sometimes sections were highlighted without my intending any highlighting to occur.
The bottom row of keys on the HP is about 4 inches from the edge of the machine, with the touchpad occupying the center of that area. My typing style as I reach across the laptop to the typing keys apparently results in touches that are interpreted by the touchpad as taps. So, the cursor jumps to wherever the mouse pointer is currently located.
I researched the Synaptics Touchpad settings and found that setting “MaxTapTime=0″ in my /etc/xorg.conf file would disable taps of the touchpad from being interpreted as mouseclicks.
I made this change and rebooted, and the problems are no long occurring.
Their comments
Where in the xorg.conf file did you place the “MaxTapTime=0”?
Thanks
