Same issue here. Xinerama / KDE / Nividia 8800GT. The "workaround" doesn't appear to work under KDE; however, trying the workaround _causes_ the bug to happen.
Haven't yet tried the downgrade of X, but will attempt. Please fix this soon, this is killing my productivity. ** Changed in: ubuntu Sourcepackagename: nvidia-graphics-drivers-177 => None -- X.org will stop responding to mouse clicks on Ibex with Xinerama.
