xresponse ==== 'xresponse' is a simple tool for meassuring UI response times to a full mouse click event. It requires the Xtest, to 'fake' the mouse event, and XDamage, to report areas of the display that have changed. Building ==== Its recommended you have the freedesktop.org autotooled xlibs installed with pkg-config (.pc ) files for xlibs, xext, xtst and xdamage.
