It gave a number of errors but sort of worked, i.e. the glitches went away and I can now switch back and forth between the two VTs, however: * Window borders in the first VT (i.e. the starting point) are now missing. * The task switcher is present but greyed out, though it still works, including the multiple desktops. * The Launcher (K menu) has gone. The second (test) VT, from which I ran the command you suggested, keeps logging errors from kwin_core related to desktops on the first VT. I can do all this again and try to log the output properly if it would help. poc _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
