touch-fix.patch

I have partial (full?) success (on the Lenovo Thinkpad Twist, an Intel-based convertible, see also https://launchpad.net/bugs/1068994 and https://launchpad.net/bugs/1015183):

I have rebuilt the current Ubuntu Raring package of xorg-server (1.13.3-0ubuntu5) with the following two patches:

1. http://cgit.freedesktop.org/~whot/xserver/commit/?h=touch-grab-race-condition-56578-v2&id=0498a4f0e0b90a850df7022a3356f10adabff855

(found via comment #17)

2. http://lists.x.org/archives/xorg-devel/2013-April/035878.html

and after that clicking via touch screen on the Lenovo Thinkpad Twist works reliably. Only remaining (minor) problems are (but the touch click ability does not get lost by them):

a. In Chromium when you create a new tab, the new tab contains icons for web apps (at least the app store and perhaps some examples). These icons cannot be clicked by touch, only with a mouse. All the rest in Chromium is clickable by touch.

b. Touch clicks do not work in XBMC, but after using and leaving XBMC with an external mouse on the normal desktop touch-clicking works again.

These are probably separate bugs which got revealed by the now working touch click.

Complete patch for xorg-server is attached.
