Bug Description

By default, the Apple Magic Trackpad has way more horizontal sensitivity than vertical sensitivity, leading to weird results on wide screens and multiple monitor setups. This means that while you can span 1920 pixels with one horizontal swipe, you can't pan 1/3 of the 1080 pixels with one vertical swipe.

The attached patch sets the horizontal and vertical resolution to be the same so that when you draw a circle on the track pad, you see a similar shape drawn by the mouse. Patch should either go into /usr/share/X11/xorg.conf.d/ or into /etc/X11/xorg.conf.d/. You must restart X in order to see changes with the touchpad. I'm preparing a similar patch for the Apple MacBook Pro built-in touch pad.

I think it's better to get the patch applied upstream, in Ubuntu, so that the fix reaches a greater number of people.

Thanks a lot for the fix!

I found a fix for another really annoying misconfiguration when using two-finger click. Often, when right-clicking something, you'll automatically click the first right-click menu item instantly, due to there not being a sufficient timeout between the two-finger click and the release.

I was able to patch this by adding Option "EmulateMidButtonTime" "100" to my patch, which I'm going to include here. Better by the day :)
