After you select which version of XFree86 you want to use and setting up the monitor and resolution you have an option to test the X configuration. When the test screen appears there is a dialog box that asks you to press the Yes button if you can read the text and resolution is OK. Also the timer is runing and after a few seconds it runs out. I think that the timer should be set higher so that there is more time left for monitors to warm up (so that you can actually read the message) after resolution change and for user to slowly read the message in the dialog box.
