I don't know if anyone else has had this problem but I couldn't get the
screen savers to unlock with this version of the KDE 2.1 RPMs. So I went
into my KDE 2.1 Beta 1 source tree and recompiled kcheckpass with PAM
support. Installed this version of kcheckpass and things appear to be
working. I can't confirm that this alone was the cause but it did correct
the problem. I also compiled in shadow support so it could have been
either one of these missing components that caused the problem with the
screensavers.
Other than that, the new CVS RPMS seem to be working well for me. And I
love the fact that they put back the lock and logout icons on the task
bar. This is something I have been sorely missing.
