Default X: multiple xscreens + mouse + touchpad = strange problem

Hello,

I'm just running sidux and I really like it, it's nice and fast and does the job :-D But, I have a problem I didn't have before.

I'm running sidux on my laptop, so I have a touchpad, all previous distributions I've tried configured it right, but sidux didn't, it worked, but there was no scrolling, so I edited xorg.conf and now I have scrolling

I also use a xinerama setup with two screens and a separate keyboard and mouse when I'm at home. But after editing xorg.conf for my touchpad it didn't support my separate mouse anymore , so I added an extra input device for my mouse and now they both work (kinda).

So, the problem is, I can move my cursor from one screen to another, with the external mouse, but it gets trapped on one screen using the touchpad. It's the same cursor, but the touchpad seems to be limited to one screen. When I move the cursor to the other screen I can move it around there using the touchpad, but when I go back to the first one it still is impossible to return.

Does anybody have any idea on what's wrong, I think it's a wrong setting in my xorg.conf

Did you ever solve this? I ask because I'm getting the same exact problem. I can move the cursor between screens with the external mouse, but not with my synaptics touchpad.

Halp?
