Have you tried launching them from the command line? Assuming you can get a terminal to open. Try KDE Menu > Run Command > xterm Some six months ago or so, I had something go wrong with my KDE 3.5.4 installation where I could not launch any KDE or Gnome applications. Basic XWindows apps would launch. The cursor would change to the bouncing ball, bounce for a few seconds, then nothing. There were no obvious errors either printed to std out at the terminal, or logged. I didn't want to reboot, because I had some applications already running and didn't want to risk ending up with nothing at all. Eventually I fixed it by renaming or deleting the dot-files in my home directory and letting them be recreated. I don't know which dot-file did the trick, but I think it may have been font related. Start with your .kde and .qt directories, then anything to do with fonts, and then work your way through everything else. Purely shell-related dot-files like .bashrc can be left alone. -- Steven
