which seems to work as long as I dont start any programs to do with KDE so presumably QT is crashing X.

I was going to post the xorg log but after starting X to get on hear it seems to have wiped the log clean again, I will post it below after posting this.

This is anoying as my main desktop manager is kde and I use quite a few QT programs.

any thoughts?
