No Gui On Boot, But Only If Mouse Not Plugged In

Hi,

I have been using openSuSe 10.3 32-bit for about a month now, and am very impressed with it. There is one problem though - if I boot up with no mouse plugged in, the X server fails to start, and stays in text mode. This is a notebook (Dell Inspiron 1520), so it has a touchpad. The touchpad is recognised and usable within the GUI when I boot with a mouse plugged in.

I have tried starting X with startx, which first shows the nVidia splash screen, and then gives the following report (back in text mode, first few lines snipped):

(EE) PreInit returned NULL for "Mouse[1]"
(snip)
Synaptics DeviceInit called
SynapticsCtrl called.
Synaptics DeviceOn called.
No core pointer

Fatal server error:
failed to initialize core devices

waiting for X server to begin accepting connections
giving up.
xinit: Connection reset by peer (errno 104): unable to connect to X server
xinit: No such process (errno 3): Server error.



If I plug the mouse in and run startx, everything starts fine.

I am using kernel 2.6.22.17-0.1, graphics are nVidia GeForce 8600M GT, driver version 169.12


Any thoughts?

Cheers,

Keith
