You'd have the advantage not being forced to wait for an hour (worst case). On the other hand you must make sure, that none of the configured knocking ports are blocked in the infrastructure between you and the server. -- Cheers, Manuel Klemenz signature.asc Description: This is a digitally signed message part.

I solved weired things like this just by removing the widget and adding it again. If this still doesn't work, you could try to rename the folder ".kde4" in your home directory and re-logon. this forces kde to create a new (and clean) default profile. The drawback here is, that you'll loose all your kde related settings... hope, the first suggestion helps ;) -- Cheers, Manuel Klemenz signature.asc Description: This is a digitally signed message part.
Re: [gentoo-user] emerge media-gfx/eog-2.30.1 fails with configure: error: conditional "HAVE_LIBJPEG_80" was never defined.
