Relief from the Tapping HorrorRelief from the Tapping HorrorThe biggest problem I've had running Linux on a Sony z505r is that the touchpad has "tapping" on by default, that is, if you tap on the surfaceof the pad, and you tap hard enough, that counts as a click. While I type, my thumbs tend to do this, leading to an annoying repositioning of the cursor, often in the middle of a phrase.
Fortunately, Bruce Kall modified his tpconfig program to work on this touchpad, in addition to Synaptics and others. His main distribution page is http://www.compass.com/synaptics/.
I repackaged version 3.0 as "tppkg.zip", which you can download here. You can decompress it again this way:
% unzip tppkg.zip
Then, read the file readme.html for more information.
