Synaptics Touchpad problem 220.127.116.11
A while ago, I compiled my own custom kernel based on the 18.104.22.168 vanilla, which all went fine. When I started up my Ubuntu 7.1 system with the new kernel (NEC Versa P520 laptop), my synaptics touchpad did not work anymore. With the standard 2.6.22-16 kernel it works fine! I don't believe that there is a problem with the supplied driver or even with the kernel. I guess there is a problem with Xorg or Ubuntu, but I have no idea what it is.
Here's my dmesg (shortened):
PNP: PS/2 Controller [PNP0303:KBC0] at 0x60,0x64 irq 1 PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp serio: i8042 KBD port at 0x60,0x64 irq 1 mice: PS/2 mouse device common for all mice

Synaptics Touchpad no synaptics event device found (checked 15 nodes) Query no Synaptics: 6003C8 [...] no touchpad detected and no repeater device unable to query/initialize Synaptics hardware
Somehow there are no /dev/input/event* entries, which are normally found according to my working Xorg log: "Synaptics Touchpad auto-dev sets device to /dev/input/event*" etc.
I don't know why my system does not recognize my touchpad with the new kernel. Any thoughts? I have tried using a linux-source (downloaded with aptitude) but that one has the same problem, even if I use my old configuration.
Actually, I had the same problem with the live cd of 8.1, which is why I am still with 7.1.
Anyone have a solution or idea what's wrong/missing? I have asked the question on the ubuntu forums, but no one there has an idea. I hoped some kernel guys here might know what I am missing... Is there a module that controls /dev/input/mouse and I am not aware of it?!
The following, which was suggested to me, did not work:
sudo dpkg-reconfigure xserver-xorg
Any help much appreciated.
