Wow! I'd say that probably has something to do with it, for sure! But
it's totally out of the blue, for me. I've never seen or heard anything
Two possibilities and if those (and sdowdy's suggestions) don't pan out,
hit bugzilla and see if there's anything close. I'd say file a bug if
you don't find anything like it, but what they're working on now is one
and a half to two years of development beyond the 4.6 you're running, so
it's probably not worth even thinking about at this point, if there's
nothing already there about it. Once the new Slackware's out and you're
on 4.8.x, however, if the bug's still there, I'd file it.
There are only two possibilities I can think of that would be anywhere
/close/ to that.
1) Check to be sure, you're running kwin as the window manager, correct?
Obviously if it somehow got replaced by compiz or the like, there'd be
some dramatic loss of window manager configurability within kde, but I've
never tried it, so I'm not sure what the symptoms would look like.
Probably the easiest way to be sure kwin's your window manager is to run
kwin --replace, from krunner or the like. You might also try from konsole
or the like, and see if it spits out any useful information as errors,
but if it's like most kde apps, devs apparently don't expect users to be
watching STDOUT/STDERR at all, so they print out all kinds of alarming
looking stuff even when things are working, for all one can tell. As a
result, that output tends to be useless for troubleshooting unless you
have another similarly configured system that's working to try it on as
well, and can do a diff to eliminate all the "normal noise".
You can also check top or kde's task list (from krunner or "the app
formerly known as ksysguard", aka the impossibly generic system monitor),
etc, and see if kwin is listed there as a running application and if
killing it kills your window manager. Do something like the following,
to be sure you're not left without a window manager for more than the 5
killall kwin; sleep 5; kwin
2) Perhaps some kwin related files are missing. I don't know how slack
breaks down its packages, but see what package contains the kwin
executable, and try reinstalling it. Also check /usr/share/kde4/services
(or the appropriate analogous dir for slack if different) for a kwin
subdir with a whole bunch of *.desktop files, and a bunch of
kwin*.desktop desktop files in the services dir itself. Here, these are
part of the kwin package too, but it's possible they're in a different
Hmm... I see one library with a very interesting name given your
hardware, too. /usr/lib(64)/libkwinnvidiahack.so.4 as a symlink to
liblkwinnvidiahack.so.4.9.1 (or whatever your kde version is, 4.6.5 IIRC
in your case), in the same dir. I'm not even sure there is such a thing
in 4.6.5 or what it actually does presumably with nvidia hardware/drivers
only, but if there's supposed to be and it's missing or corrupted, that
could throw a monkey wrench in who knows what. Again, here at least,
it's part of the kwin package. (You may not have the symlink, just the
actual library, on a binary distro that splits its libs into separate
runtime and -dev packages. That'd be more trouble than it's worth on
gentoo, since there /everything/ is generally built from source, so
keeping the dev bits in the same package is simply easier and less
Hopefully it's one of those two items, as that's about all I can think of
that would leave you with an empty effects list! That was a TOTAL
surprise here -- I didn't see THAT coming AT ALL!
