I've seen this pop up in the forums repeatedly with no real resolution.
I'm running Lubuntu 11.10 on a Dell Latitude D510. I hate the tapping feature of the touchpad but haven't found a way to permanently disable it.
Currently, I start Lubuntu then open a terminal screen and run:
The terminal window shows: "An X error occurred. The error was BadAtom (invalid Atom parameter)" and the Gpointing window opens.
I click on the AlpsPS/2 Alps button then the "Tapping" tab and see that the "Disable Tapping" button is already checked.
I have to uncheck, then recheck the button to actually disable tapping. I then close the windows and tapping is disabled for that session only. Every time I restart the computer I have to do the same thing.
How can I make this change permanent and why am i getting the X error? Thanks.
