Experimenting with switchdesk, I changed to the XFce desktop which went fine. But, I can't go back to Gnome, or to KDE, or to TWM. Switching back to the "default" desktop didn't work either. Switchdesk suggested deleting the .Xauthority file which I did but that caused an endless list of error messages. GNOME now issues messages about not being able to start the "Settings Daemon", or the Gnome-clock-applet, or loading OFIID, or Bonobo - Warnings, or the GdkPixbuf assertion 'filename != NULL' failed, and Warning: destroyed file still being monitored. X windows, for root at least, is now almost useless. I can only open one terminal window within the GUI. For the record, This is a pure test/learning machine and no data will be lost. I guess that I can copy the configuration files from another account or do a reinstall, but I'd like to know if this is a bug or something I did wrong. Thank you. Dwaine
