Yes, that's because of the UID change. You can run the following (as root) while running F15 to change your F15 UID/GID to the F16 values and you won't have this problem: groupmod -g1000 tim usermod -u1000 -g1000 tim chown -R tim.tim /home/tim This assumes that your UID and GID on the F16 system is 1000 (and that 1000 isn't taken on the F15 system, which is unlikely). Make sure to run "echo $UID" or check /etc/passwd on your F16 system to ensure that is the case. Note that changing the UID/GID on the F16 system to match the F15 value is inadvisable because system daemons most likely have already been assigned UIDs between 500-1000. -T.C. _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
