No, I don't use pulse-audio. It's not too bad, when I see the CPU running,
it usually is those two processes, and just kill them. This does not seem to
harm, I hope this is true. My current strategy is to wait for 4.7 and see if
it still happens.

Although there are few system sounds I hear, so I probably wouldn't even
notice they're gone, I somehow would not like to be without any.

I'm using GStreamer, and Xine is also on the list. I think I read one is
deprecated and the other should be used, but I do not remember which was
And now that you mention phonon-vlc, I remember reading somewhere about it
and it sounded good. So I emerged it, and switched the backend. Whoops,
Amarok crashed. But it seems to work fine, let's see if the situation with
kded4/knotify4 improves. Although it didn't happen for 2-3 days now.

I once fixed some problems with this file, when the desktops had switched
their order. This happened for again a couple of times, but now I just copy
back the file from a backup. I did not dare to remove more of the cruft,
because I am not sure if it really is cruft, or if I might damage some
The last time I started with a clean .kde directory was June last year, with
KDE 4.4.4. BTW, I looked up the date by googling for a posting of mine on
the gentoo-user list where I mentioned this, in a thread about KDE4
problems. I first wanted to look this up browsing through my archive of this
list, which I thought I had moved from my IMAP server to local already.
Which is not true, but this way I found out that all of my local mails are
gone. Here's what I wrote on this list about these folders:
Still, my local mail folders were missing - the 'Local Folders' resource
points to .local/share/local-mail/, and when I change this to
.kde4/share/apps/kmail/mail, my folders there do not show up. So I created
a 'KMail-Maildir' resource, pointing to that directory. So, even if the
locations of both the 'KMail-Maildir' and the 'Local Folders' point to the
same directory, only the former displays my custom folders. Then I moved
my custom folders with KMail into the 'Local Folders', and FINALLY, things
are back as they were.
My local mails have a 'Backup' folder with sub-folders for things like
mailing list archives I do not want to have on the IMAP server because of
their size, and because I rarely need them. The 'Backup' folder is still
there, but no sub-folders.
Good thing I have my backup. So I just started rdiff-backup-fs in order to
browse through the snapshots. Right at this moment, or maybe a little
earlier, system load went up A LOT, to about 45. The cause were kded4
processes, in total I had 39 of them! Killed them. They were running as my
user, while those two pairs of kded4/knotify4 I sometimes see run as root,
at least some of them.
And there was one acroread process eating CPU time. ps -axf shows it was
started by nspluginwrapper, which was started by 'kdeinit4: konqueror
[kdeinit] --silent'. What is going on here...
I think I should rename the subject to Wonko's KDE4 live ticker... I just
answered a mail that came on another mailing list and was CCed to me. This
makes it show up in my inbox, not in the mailing list. So I did a 'Reply to
All', and cleared the 'To:' entry. The CC field automatically got cleared
and its content moved upwards into the To: field. But when sending I got a
message that the To: field is empty. I could send it after I simply copied
the text and pasted it again in the To: input field.
I like to make screenshots of such events, this way I noticed that the
PrintScreen key no longer starts KSnapshot. I wanted to take a note of this
in my KNotes KDE4 log, but the KNotes icon in the system tray does not react
to left button clicks. I had this before once. Other things in the tray
work, but the KMix icon looks different now (colored, not only white as it
used to be), and it opens the mixer when pressed, instead of showing a
volume slider. Oh, and the hidden icons (accessible by clicking the little
white arrow at the right) are all visible. Well, the next login will
probably cure this, seems it's about time.

Let's see if this will make you use Konqueror again.

Strange, it always showed them here.

Doesn't this give you lots of browser windows? Or does this open tabs in an
existing Firefox windows? That's how it is here, but when I have multiple
windows open, new tabs open in the last window I used, which often is not
the one I want to have the tab in. So I prefer the tabs to be in Akregator

Until four years ago, I used the ancient DOS software CrossPoint for this.
It did both mail and news, and I really liked that it could show discussions
in different usenet groups AND mail in the same thread display. Using the
keyboard only it was quite fast. Over time, the setup grew somewhat
complicated - I used the Linux version only to download and send messages,
and the DOS client as frontend, because in Linux I never got some keys to
work and also had other problems. And some years earlier there I even had to
use some DOS programs running in an Windows NT VM for data exchange. It was
a very big hack.
HTML became more important, attachments could be viewed in external viewers,
but they still were inside DOS, with 8.3 filenames, and I finally switched
to other mail and news clients. But I still miss some of its features.
So, this mail is done. One last weird thing: All my six desktops suddenly
show plasmoids from the last desktop only. Time to log out, and probably
copy back that plasma-desktop-appletsrc file again.
