No mouse pointer on secondary monitor
 

I'm running KDE on Redhat 9.0 Vernal build 2.4.20-31.9. I've set up a multi head display using a Matrox Millennium G200 Quad pci card. I configured Xfree 4 to use three of the four pci addresses on the card. (eg. 02:00:00, 02:04:00, and 02:08:00). My primary and secondary are identical.

Here's my first problem:
I've got a mouse pointer on the primary display but when I move the point to the secondary or tertiary it disappears. I can drag windows from monitor to monitor without any problem I just can't always see where I'm clicking.

My second problem:
I have a black strip on the bottom of the secondary monitor. It's a sort of dead zone where no pixels are being sent. The resolution seems to be the same because the windows do not change size when moving from the primary to the secondary.

If anyone has any suggestions for either of these problems your help would be greatly appreciated.

in the device section for that head, addas for the space... dn't quite follow... is there meant to be stuff there that is not drawn, or the screen is just squashed up?

The screen is not squashed up. Everything is in correct proportion. There is just a black region taking up about 1/4 of the monitor on the bottom where nothing is drawn. I switch monitors thinking that it may have been a hardware problem with the monitor. It worked fine as the primary, so I'm certain it's something in software.

Thanks for taking the time to help me out. I just finished the above suggested configuration of the XF86Config file. Here's what it looks like:

Everything looks ok to me, but I still have no cursor on any monitor other than the primary, and an annoying black region where nothing is being drawn on the secondary.
