Comment 17 for bug 337351

I liked your idea of trying SSH, I didn't think of that myself.
Its nice to know the computer isn't completly dead just the user interface / display updating is messed up.
Not that I know much about how X works but I'm guessing there are events which are sent to each window telling it to update and those event signals are not being sent anymore, hence they don't update when your mouse hovers over them etc. As the mouse still works and X isn't using 100% CPU then it appears there is something stopping the update event signals but that could be many things... :(
Never the less, we've clearly identified a critical problem which seems to be KDE related that is breaking X. As I've not seen this issue on Ubunutu 9.04 then I'de say its definatly a Kubuntu or KDE problem. I'm trying to think what would have the power to stop applications from within X from updating and I can only guess something pretty fundamental is happening, I doubt its a user space program thats stopping X from asking the applications to update :/
