I've added a set of patches to evdev that are necessary for evcalibrate/evdev to function properly with certain eGalax and 3M touchscreens. More information is avaialble at http://whilesoftware.com
Added a call to QWidget::showFullScreen() on app start. This eliminates the previous need to manually set the window to fullscreen (via wmctrl or some other tool).
The latest revisions are always available from the svn repository, https://evcalibrate.svn.sourceforge.net/svnroot/evcalibrate
