ADDITIONAL INFORMATION
After login, I ran the commands below to try to get more information and it is
complaining first about a parse error in kwin.upd and then that an update
script does not terminate (for kwin.upd). It hangs 30s, not 60s as shown in the
output below. I think this is causing the slow login because I can see that
when kconf_update terminates, the mouse cursor comes back.
