I've recently set up XFree86 on a Dell Inspiron 8200 laptop with a dual screen. The screen on the laptop is 1600x1200 and the other screen is a Dell 20" LCD screen (I'm using the analogue port, since the Inspiron 8200 has no digital output port). After some tweaking to get it working, and forcing XFree to use 70Hz on the external LCD instead of the default 60Hz, the display part works fine and looks very nice. My laptop has only one PS2 port (which can be used for either a keyboard or a mouse). In the "one screen setup", I have used this for an external mouse, and this has worked fine. In my new "two screen setup", I needed the one PS2 port for an external keyboard. This meant changing the mouse setup. The Inspiron 8200 comes with a touchpad, which works as a "primary" mouse. Usually I plugged the secondary mouse to the PS2 port, but since the external keyboard needed that port now, I had to move the mouse to one of the USB ports. Getting the mouse to work properly was not self-explanatory, and required me to make sure some kernel modules were properly loaded. Initially, everything seemed to work fine, and I had both the touchpad and external mouse being active at the same time, using a "two pointer" setup in XFree86. The internal mouse was marked as primary (using "CorePointer") and the external as secondary, using "SendCoreEvent", as illustrated below: Section "ServerLayout" Identifier "Both" Screen "ScreenLaptop" InputDevice "PadMouse" "CorePointer" InputDevice "USBMouse" "SendCoreEvent" InputDevice "Keyboard0" "CoreKeyboard" Option "AllowMouseOpenFail" "true" EndSection Before I started tweaking this setup, it seemed to work, except the external mouse seemed to mysteriously loose mouse events. For instance, double clicking with the external mouse was very hard (no "double click" events were being triggered). Double-clicking still worked fine on the built in mousepad. Further tweaking, led me to use the "usb-uhci" module, and with this and some further tweaks to the USB mouse definition, I finally managed to get the external mouse working properly. But then I can only get one of the mice working at the time. Only the mouse marked as "CorePointer" will work. The other one marked with "SendCoreEvent" will not work. If I exchange the two, the one marked as "CorePointer" will work, but the other one will not. While this is "good enough" for most of my usage, it makes it hard to unplug the laptop and keep working "detached" from my usual setup (I have to restart X with the "CorePointer" mouse setting set to the built-in mousepad). Any idea on why I am having these problems, and what I need to do to fix it? I've attached the mouse definitions I use below for reference. Any help would be appreciated.
