twinview: windows maximize across both monitors

[purecharger]

Binary package hint: xorg

After upgrading to 10.04 from 9.10, the window manager (compiz) does not treat my 2 displays as it did with 9.10. Now windows maximize across both screens, they do not snap to the screen boundary, my lower task bar (where apps get minimized to) extends across both monitors without appearing: by that I mean I dont see it on the 2nd monitor, but I can not resize a window into the area that it would take up on the 2nd monitor.

The alt+tab switcher and all windows that launch in the center of the screen are split across the monitors.

I have my 2 screens in both nvidia-xconfig and CCSM defined as: 0,0+0+0 and 0,1920+0+0

I have solved this by ensuring that my window manager, Compiz, now starts up properly when I log in to my session.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
