Nothing to do with KDE's wallet; that's for unlocking passwords within KDE apps -- it's not used by GTK apps like Symantic. > I wouldn't have been able find the missing package in a million years. There's no way to know now what the cause of the issue was, but as I said I dont't think it was related to a /missing/ package; dependencies take care of that. Regardless it's fixed now, and that's what matters most. > The way you get Mate from an added repository rather than from a CD or > setting out to get it doesn't help. > > But it's like a homecoming to see the old gnome 2 desktop back.

It's only the Nepomuk/Strigi parts of KDE that do this, but it doesn't store files in memory -- it caches them in a Virtuoso database. Nepomuk is the feature that searches this database and manages this, Strigi is the file indexer that searches your system periodically with many simultaneous background I/O processes (which is what brings your computer down to "slideshow" speed) and then adds both files and metadata to the Virtuoso database. Where this becomes a memory problem is when Nepomuk has to search a Virtuoso database that is huge -- which it quickly will be if you let Strigi fill it and you have lots of files in your home directory. > > Mark > > On 12-11-12 02:38 PM, Chris Knadle wrote: > > On Monday, November 12, 2012 12:43:01, Mark Wallace wrote: > >> Synaptic Package Manager does not boot up in Mate.
