[opensuse] A New-Old KDE question

Hello folks! Does anyone know where KDE stores the current position & size of objects on the desktop, particularly icons? I have a large number of icons on my desktop organized into functional groups. After an X crash and recovery, the desktop icon layout is messed up. ( A typical scenario is X or KDE or the keyboard and mouse freezing up. The the only way out of it, is to telnet in from another system on the network, su and init 3. If that fails, you can force a reboot.) It would be nice to force KDE to write back this stuff on demand or every n minutes. Daniel
