In kernel 2.6.11 detection of the Alps touchpad is already correct, only the initialization of the driver is disabling the double tap hardware detection, as you can see literally in the dmesg, Alps touchpad detected and double tap hardware detection disabled. In kernel 2.6.12 it is supposed to change this double tap hardfware detection disabling, as software double tap handling is not reliable (at least this was the tone in several mail exchange in kernel lists some weeks ago when I was searching about the problem - see more below. Some people managed the Synaptics driver in XFree86/Xorg, using information available in synaptics driver home page (already referenced in this thread) and in a specific Alps readme file in the driver package. By changing the config values using a command line utility, synclient, if I remember well, you can make double tap to work. The big difference of using the 2.6.11 alps/synaptics driver is that you can have some advanced gestures like scrolling vertically/horizontally by sliding the finger in the right/lower edge, tapping with 2 or 3 fingers simultaneosly and getting the touchpad detect this as 2 or 3 mouse button press, etc. By chnaging the timings I sometimes can get a double tap detected even in 2.6.11. Also in the driver there is another utility to disable touchpad when you start typing for avoiding change of cursor position. Finally, a quick search on kernel list showed this: http://seclists.org/lists/linux-kernel/2005/Mar/2703.html Hi Linus! Now that 2.6.11 was released, I've got these nice 128 patches pending for 2.6.12. They include many fixes, several new drivers (mainly for touchscreens, and less common architecture keyboards), refactoring of gameport core to fix possible races, race fixes in serio. The patches all have been in -mm for a while, some longer, some shorter, and got testing in the SuSE kernel as well. I'm pretty confident they fix a lot, and don't break much. .... [EMAIL PROTECTED], 2005-02-04 20:04:21+01:00, [EMAIL PROTECTED] input: When hardware tapping is disabled on an ALPS touchpad, the touchpad generates exactly the same data for a single tap and a fast double tap. The effect is that the second tap in the double tap sequence is lost. To fix this problem, this patch enables hardware tapping and converts the resulting tap and gesture bits to standard finger pressure values (z), which is what mousedev.c and the userspace X driver expects.
