[PD] HID problem in Xubuntu.

Hi  Hans,

I've been checking the archives and found only one issue that has to do with the ubuntu problem and sais to put this line:
KERNEL=="event[0-9]*",                  MODE="0666"

in /etc/udev/rules.d/40-permissions.rules file.

The problem is that xubuntu 9.04 (jaunty) doesn't have this file 
any more and permissions.rules, i think, are given in other archives... 
i'm looking in ubuntu forums to see what can i do... If someone 
knows something about...

I have already tried to create the archive but it didn't work 

thanks again,

Chances are that the trackpad is an USB device, but just internal.  But I don't think that's the issue.  I think in recent versions of Ubuntu, the X server or related process grabs the keyboard and mice using exclusive access.  You have to tell the X server to not use the mice that you want to use with [hid].  Check the archives, there is quite a bit of discussion about it.  It would be great to have a wiki page about this...

Hi Simon,

Thanks for the fast response. No, it isn't. It's the standard  synaptic touchpad that comes with many laptops.

is your touchpad a USB HID device?
