I have notice today that the touchpad of my Acer Aspire 5024 wasn't recognized anymore by the x server as a synaptics one, even if the kernel says (according to dmesg) that it is a synaptics one. After investigating for a while I have noticed that the device associated to it has changed from /dev/input/event1 to /dev/input/event0 according to /proc/bus/input/devices. Since in my xorg.con I have the line
Option "Device" "/dev/input/event1" of course the server couldn't recognize it. My question is: why has it changed? (I am sure that before it was event1, I had checked it in /proc/bus/input/devices and it worked) Could it be due to the installation of a new kernel?
